What's next for One Lake?

6/10/2019

 
Picture

​One Lake project's Feasibility Study/Environmental Impact Statement (FS/EIS) and other required documents may be sent to the Army Corps of Engineers as early as this September, a spokesperson for the Pearl River River Vision Foundation reported at the Rankin Hinds Pearl River Flood and Drainage Control District (Levee Board) meeting  this morning.  Here's a partial list of all of the potential hurdles required of the Levee Board before and after the FS/EIS report is sent to the Corps. 

Before sending the FS/EIS to the Corps, the project sponsors must:
  • Incorporate and address all Draft EIS public comments submitted during the most recent public comment period
  • Incorporate and address all Army Corps of Engineers Draft Agency Technical Review comments to Draft EIS 
  • Obtain required Independent External Peer Review
  • Obtain required Biological Opinion from United States Fish and Wildlife Service (USFWS)
  • Obtain required Fish and Wildlife Coordination Act Report from USFWS
  • Obtain required comment letters from all pertinent Federally Recognized Indian Tribes and conduct additional cultural resource studies/examinations, per Section 106, National Historic Preservation Act
  • Schedule, pay for and obtain Final Agency Technical Review from Army Corps of Engineers

Once complete, send FS/EIS and other required documents to the Assistant Secretary of the Army for Civil Works ((ASA(CW)).  Upon receipt of the FS/EIS, the ASA(CW) will refer the study to the Chief of Engineers for review and comments.  The ASA(CW) will review for compliance with law, policy and procedures.  ASA (CW) will submit to the Committee on the Environment and Public Works of the Senate and the Committee on Transportation and Infrastructure of the House of Representatives a report that describes whether the project if feasible and any recommendations or conditions.  Office of Water Project Review (OWPR) will prepare comments. OWPR will dispatch letters transmitting information regarding the project proposal, draft environmental compliance documents and related documents to State and Federal agencies for comment.

Once the FS/EIS is deemed acceptable to the ASA (CW), the project sponsors must:
  • Publish the FS/EIS to the Federal Register for comments
  • Facilitate another public comment period
  • Incorporate and address public and agency comments into the FS/EIS
  • Transmit Final FS/EIS to ASA(CW)

ASA(CW) will prepare a Finding of No Significant Impact or Record of Decision.  ASA(CW) will submit its recommendation to the Office of Management and Budget and then to Congress.

If ASA (CW) issues positive Record of Decision, the project sponsors must then:​
  • Raise money to pay for project design
  • Conduct pre-construction engineering and design 
  • Develop required Adaptive Management Plans for habitat loss replacement and reconstruction
  • Complete purchase of mitigation properties necessary for Adaptive Management Plans
  • Conduct engineering, technical and environmental studies of identified Hazardous Toxic and Radiological Waste (HTRW) locations in the project area to include several unregulated, unlined landfills and a creosote slough (Map of HTRW locations)
  • Develop HTRW mitigation plans and obtain approval from EPA and Mississippi Department of Environmental Quality (MDEQ)
  • Pay for removal and/or mitigation of project-area HTRW sites
  • Obtain Mississippi Department of Transportation (MDOT) approval for bridge engineering solutions (One Lake Project could lead to bridge failures, MDOT says)
  • Facilitate creation of a multi-city development master plan (Jackson, Flowood, Pearl and Richland will be responsible for developing, maintaining, and policing new properties)
  • Establish covenants to control land use and development along the riverfront
  • Obtain necessary EPA/MDEQ permits including ACE wetlands permits, ACE rivers/harbors permit, endangered species and marine mammals takings permits, coastal consistency review, Section 401, 402 and 404 permits, Federal Clean Water Act Letters of Permission, MDEQ minimum flow requirements and National Pollutant Discharge Elimination System permits
  • Conduct public comment periods associated with EPA/MDEQ permits
  • Receive authorization from Congress to create a structure that impedes the navigable capacity of   waters of the United States (Rivers and Harbors Act)
  • Outline legal arrangement between Pearl River Valley Water Supply District (Ross Barnett Reservoir management) and the Rankin-Hinds Pearl River Flood and Drainage Control District (Levee Board)
  •  Conduct voluntary buy-outs of any properties in the project area
  • Expand the Levee District to encompass any residences or properties in the One Lake project area that will directly or indirectly benefit from the project
  •  Levy special improvement assessment taxes on properties in the new Levee District
  •  Obtain state bonds to pay for the local cost share of the project
  •  Lobby Congress for funding appropriation of the federal cost share
  •  Receive funding appropriation from Congress
  •  Conduct project construction 
  • Obtain new Federal Emergency Management Agency (FEMA) mapping of the flood plain
  •  Sell property along newly constructed lake
  •  Pay annual maintenance and debt service costs estimated at $600,000 per year

Sewage Overflows Continue

5/8/2019

 
Picture
23.6 million gallons of raw sewage and billions of gallons of minimally treated sewage to the Pearl River and its tributaries in the first quarter of 2019.  From Jan-March 2019, 65 separate Sanitary Sewer Overflow (SSO) discharges to "Waters of the State" occurred from the collection system sewer lines associated with the Savanna Street Wastewater Treatment Plant (WWTP).  In the first quarter  2019, raw sewage released from the West Bank Interceptor line totaled 23 million gallons, 4 times the total amount of raw sewage released during the entire year of 2018.  Untreated sewage has flowed into most of the Jackson creeks that lead to the Pearl River, including Town, Eubanks, Belhaven, Lynch, Hanging Moss, Eastover and others.

Read the 2019 Quarterly Report
What is a a Sanitary Sewer Overflow?
A Sanitary Sewer Overflow (SSO) is an event in which untreated sewage is discharged from the sewage collection system into the environment prior to reaching the sewage treatment facilities.  These discharges endanger human health, cause property damage, and degrade our local water quality. ​
  • Health impacts: Sewage spills contain bacteria, viruses, and a host of other pathogens.  Health hazards range from mild gastrointestinal discomfort to more serious illnesses such as Hepatitis and Dysentery. 
  • Environmental impacts: Spills degrade water quality by increasing the concentration of pollutants and nutrient levels which in turn decreases the amount of  dissolved oxygen in the water.  Low dissolved oxygen can cause fish kills and is harmful to all aquatic species.  Since 1996, the entire "Jackson Segment" of the Pearl River has been listed by MDEQ as "impaired" for nutrients/organic enrichment and low dissolved oxygen.  The "Jackson Segment" is not meeting even the lowest MDEQ water quality standards for aquatic life support or contact recreation.  The City of Jackson is rendering this entire section of the river unusable. 
What causes SSO events? 
The SSO events experienced by the City of Jackson collection system were caused by excessive flow,  collapsed pipes, grease/fat buildup, and blockages from roots and solids. Higher than average rainfall in the first quarter of 2019 overwhelmed the system.  In addition, the City of Jackson's aging sewer lines are crumbling and collapsing in many areas.  
EPA Consent Decree
In November 2012, the Jackson City Council entered into a consent decree with the EPA and MDEQ regarding operations at the Savanna Street Wastewater Treatment Plant.  The consent decree required the City to pay a civil penalty of $437,916, execute a $875,000 environmental project, and overhaul its wastewater treatment plant and collection systems.  The City was given 18 years to fully comply, with the vast majority of the work to be completed within the next 11 years (by 2023).  The City of Jackson was required to develop prioritization work plans, rehabilitation plans, preventative maintenance programs and supplemental environmental program timelines.  The City is required to submit quarterly, semi-annual and annual reports to the EPA and must publish these on their website.

Recent City of Jackson actions
  • In 2016, the City borrowed nearly $70 million from the MDEQ Water Pollution Control (Clean Water) Revolving Loan Fund (WPCRLF) to upgrade Trahan-Big Creek POTW and to rehabilitate the West Bank Interceptor.  ​According to the most recent semi-annual report, 37% of the West Bank Interceptor has been fully rehabilitated with plans in place to rehabilitate a total of 50% by 2022, as funding is available. The Consent Decree required 20% rehabilitation by 2022.
  • In March 2018, the City approved $1.6 million in various emergency contracts for repairs to water lines and consent decree improvements. The money came from the water/sewer fund which would later be replenished with money from the 1-percent tax.  ​
  • ​In April 2018, the Jackson City Council approved taking out a $31 million loan through the MDEQ Water Pollution Control (Clean Water) Revolving Loan Fund (WPCRLF) Program to pay for improvements at the Savanna Street WWTP.  In June 2018, the Jackson City Council voted unanimously to approve $10 million in contracts for water and sewer repairs.  In June 2018, the City of Jackson submitted a Request for Proposal (RFP) from "qualified engineering firms to complete the design and assist with bidding and construction of the Savanna Wastewater Treatment Plant (WWTP) Phase 1 improvements.  The project is intended to restore operational capability and capacity of existing unit processes and systems."  In August 2018, Neel-Schaffer Engineers were selected as the design consultant.  The firm is now under contract with the city and expect to have Phase 1 improvements advertised for construction bids by August 2019.  ​
Consent Decree Renegotiation
​The City of Jackson has requested that the EPA review the Consent Decree for potential renegotiation citing lack of funding to complete the necessary requirements of the original decree.  The EPA is currently working through that process.  If there is a "major modification" to the Consent Decree, then the amended decree will go to public notice with an associated public comment period.  Pearl Riverkeeper will keep you updated if this occurs. 
Savanna Street Wastewater Treatment Plant
According to the 2019 first quarterly report, there has been an ongoing "Prohibited Bypass" at the Savanna Street Wastewater Treatment Plant since Dec 9, 2018.  A "Prohibited Bypass" occurs when the plant is overwhelmed with excessive flow, usually due to high rain events, and bypasses must occur.  "All bypassed volume is chlorinated, de-chlorinated and required samples taken prior to blending with the mechanical plant effluent and subsequently discharged to the Pearl River".  As of the end of the first quarter reporting period, 2.47 billion gallons of minimally treated sewage has been discharged to the Pearl River.  
EPA Database, Savannah Street Facility Report
Is public notification required during an SSO event?
  • According to City of Jackson Sewer Overflow Response Plan, City of Jackson will issue a news release and place temporary signs in the area of the overflow whenever an overflow creates a "significant health hazard" or "significant volume has reached waters of the US and/or State".  Additional notification will be considered in conjunction with MDEQ and HCHD.  
  • In the first quarter of 2019, there were 7 SSO events that released more than 10,000 gallons of raw sewage to Jackson neighborhoods and tributaries.  4 events that released more than 100,000 gallons.  And 2 events that released more than 1 million gallons of raw sewage (408 S Jefferson St).
  • In 2017, 2018 and 2019, zero SSO-related water contact advisories were issued for the Pearl River or its Jackson-area tributaries.   In fact, the last MDEQ-issued Water Contact Advisory for the Pearl River was issued on Oct 29, 2013.  
  • Pearl Riverkeeper finds this lack of reporting unacceptable and is working with City of Jackson Public Works to review and make changes to the current notification process.  Public notification is required to protect the health of the citizens of Jackson and those who use the river.

What's in our Water?

4/8/2019

 
According to EPA's most recent Toxic Release inventory (TRI) National Analysis, over 4 million pounds of toxic chemicals were dumped into the Pearl River in 2017.  The vast majority of this toxic waste came in the form of nitrates from 3 poultry processing companies, Tyson Foods, Sanderson Farms and Peco Foods.  
Picture
Nitrate pollution has numerous "external costs" to the environment which are not paid for by the companies discharging this toxic waste.   These external costs, borne by the taxpayer and the public in general, include:
  • Loss of tourism and recreation revenue
  • Decline in property values
  • Algae blooms, eutrophication (reduction in dissolved oxygen) and fish kills
  • Dead zones in the Gulf of Mexico
  • Commercial fishing: reduction in harvest and increased processing costs associated with elevated shellfish poisoning risk
  • Human health: heavy metals and pathogenic microbes in nitrate waste can cause harm and disease through direct contact with skin, consumption of drinking water or contaminated shellfish
  • Increased drinking water treatment costs
  • Restoration: costs associated with restoring impaired waterbodies and developing Total Maximum Daily Load (TMDL) and other watershed plans

In addition to the nitrate compounds dumped by the poultry processing industry, Georgia-Pacific and International Paper together contributed 335,159 pounds of toxic discharges to our watershed, including manganese compounds, methanol, nitrate compounds, ammonia, barium compounds and acetaldehyde. Georgia-Pacific paper mill in Monticello, MS released 13,864.62 pounds of carcinogenic acetaldehyde to the Pearl River. 

This Pearl River Basin chemical discharge data was compiled from the EPA's 2017 Toxic Release Inventory (TRI) National Analysis Report of chemical discharges to air, land and water.  "The TRI tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. Certain industrial facilities in the US must report annually how much of each chemical is recycled, combusted for energy recovery, treated for destruction, and disposed of or otherwise released on- and off-site." The  discharge of these chemicals is legally authorized by each state through the National Pollution Discharge Elimination System.  Mississippi and Louisiana Departments of Environmental Quality test their waterways, designate the waterway sections as "attaining their designated use" or as "impaired" and make Total Maximum Daily Load (TMDL) discharge determinations.  The TMDL is then used as the basis for discharge permit authorizations.  


​"Since the creation of the TRI Program, the information collected and presented has provided a way for citizens to better understand possible sources of pollution in their communities.  This better understanding can be the basis for actions, such as communications with facilities releasing chemicals to the environment and with regulatory authorities that have oversight responsibilities.  This concept of citizen empowerment is summed up by the slogan, 'A Right to Know, A Basis to Act'."  EPA.gov.


Louisiana ranks 4 out of 56 states/territories nationwide based on total releases per square mile (rank 1 = highest releases). Mississippi ranks 11 out of 56.  The TRI is easily searchable by state, county, city or zip code: https://www.epa.gov/trinationalanalysis/where-you-live.

Task Force

1/24/2019

 
Fascinating video of the One Lake project discussion at the Lower Pearl River Basin Task Force meeting, Louisiana State Senate. Particularly interesting discussion at the 1 hour 11 minute mark about serious impacts to water quality in Louisiana. Probably not good if a discussion of your DEIS includes comments like "they have some explaining to do", "that blows my mind; I can't believe what I am hearing", "pretty scary" and "do it first, hope for the best". Definitely worth the watch.

Sanitary Sewer Overflows

12/12/2018

 
Picture
Over 4.5 million gallons of raw sewage has been discharged into the City of Jackson urban creeks during the first three quarters of 2018.  From Jan-Sept 2018, 120 separate Sanitary Sewer Overflow (SSO) discharges to "Waters of the State" have occurred from the collection system sewer lines associated with the Savannah Street Sewage Treatment Plant.  Untreated sewage has flowed into most of the Jackson creeks that lead to the Pearl River, including Town, Eubanks, Belhaven, Lynch, Hanging Moss, Eastover and others. 
What is a a Sanitary Sewer Overflow?
A Sanitary Sewer Overflow (SSO) is an event in which untreated sewage is discharged from the sewage collection system into the environment prior to reaching the sewage treatment facilities.  These discharges endanger human health, cause property damage, and degrade our local water quality. 
  • Health impacts: Sewage spills contain bacteria, viruses, and a host of other pathogens.  Health hazards range from mild gastrointestinal discomfort to more serious illnesses such as Hepatitis and Dysentery. 
  • Environmental impacts: Spills degrade water quality by increasing the concentration of pollutants and nutrient levels which in turn decreases the amount of  dissolved oxygen in the water.  Low dissolved oxygen can cause fish kills and is harmful to all aquatic species. 

What causes SSO events? 
The majority of the SSO events experienced by the City of Jackson collection system were caused by either grease buildup or collapsed pipes.  Other causes include excessive flow and blockages from roots  and solids. The City of Jackson's aging sewer lines are crumbling and collapsing in many areas.  View this City of Jackson video to learn more about how you can help reduce buildup of fats, oils and grease in the sewer system collection lines.

​How can SSOs be reduced or eliminated?
  • Consistent investment and maintenance of sewer collection systems is necessary to decrease the frequency and severity of sewer overflows to the Pearl River. The aging sewer lines and pipes must be upgraded to accommodate current needs and future growth.  ​
  • Sewer system cleaning and maintenance must receive adequate staffing and funding.
  • Residents can help by limiting fats, oils and grease (FOG) released to the sewer system.
The sewer collection system of a large municipality is an asset worth billions of dollars.  Properly funding ongoing maintenance and rehabilitation adds value to the original investment by maintaining the system's capacity and extending its life. 

Is public notification required during an SSO event?
Currently, neither the City of Jackson, MDEQ or the MS Department of Health is required to notify you if an SSO occurred in your neighborhood.  In the event of an "overflow creating significant health hazard or significant volume has reached waters of the US and/or State", "(City of Jackson) will issue a news release and place temporary signs in the area of the overflow.  Additional notification will be considered in conjunction with MDEQ and HCHD."

Tire-less Pearl

11/5/2018

 
Picture
     Norman Sisson and his Pearl River Clean Sweep team were the first to report the massive tire dumps on the Pearl River between the Old Brandon Rd bridge and Highway 80 in Jackson.  The tires had likely been marring the landscape of the river for decades; hundreds of them imprinted with dates from the 1960's to early 2000's.  This forgotten wasteland could be seen every time travelers passed over the Highway 80 bridge on their way to and from Jackson.  The dump was located less than 2 miles from MDEQ headquarters yet it remained in place, leaching contaminants into the water and soil, providing a haven for mosquito populations and contributing to the blight that plagues our capital city.   
Picture
     The local news reported on the issue here and here.  Pearl Riverkeeper escorted members of the City of Jackson and MDEQ to the location on two separate occasions.  Plans were initiated by MDEQ to remove the tires.  Yet, one year later, when Norman Sisson again led his crew of boaters and kayakers down river to clean up this section of river, the tire dump remained.  That is, until 2 Mississippi natives and local fishermen decided enough was enough.  Concerned that the tires were being swept downriver after each high rain event, John Breland mobilized some friends for a Saturday morning cleanup event that exceeded all expectations.  Over the course of several hours, John, Berry Blanton and 8 other dedicated volunteers removed 204 tires from the west side sandbar, leaving the area completely free of all trash, debris and tires. 
     Shout out to organizer and leader, John Breland, heavy equipment operator, Berry Blanton, and all of the other hard-working volunteers for leaving this area better that the way they found out.  You can thank them for contributing to a cleaner swimmable, fishable, drinkable Pearl River.

2018 Swim Guide Summary

9/26/2018

 
Picture
     This summer, Pearl Riverkeeper volunteers conducted weekly E.coli testing at four Ross Barnett Reservoir locations in order to provide you with information about whether it was safe to swim! 
     Neither the MS Department of Environmental Quality nor the MS Department of Public Health conducts this type of weekly E.coli testing on our freshwater rivers and reservoirs.   We think that's a shame, so our volunteers spent Wednesdays in the summer testing your favorite Ross Barnett Reservoir locations to keep you informed!
     E. coli, a bacteria found in the intestines of warm-blooded animals, can enter our waterways through agricultural runoff, wildlife, and leaking septic/sewer systems.  Human risk of getting sick from recreating in open water increases as E. coli concentration increases and young people and people with a compromised immune system are at greater risk.  E.coli itself can cause illnesses such as "swimmer's ear", upset stomach, and diarrhea, and E.coli can also indicate the presence of other more harmful bacteria such as Salmonella, Shigella and Giardia.
     Pearl Riverkeeper volunteers conducted 56 E.coli tests during 14 weeks in May through August at Natchez Trace Overlook, Old Trace Park, Lakeshore Park and Pelahatchie Bay Fishing Pier.  Results were posted each Friday on the Pearl Riverkeeper website, Swim Guide and through text alerts.  A location was marked Green if the test met EPA water quality standards or marked Red if the test exceeded the standard.  We issued 9 "high E.coli" alerts over the 14 weeks of summer.  Read the full results.

     What the data shows on the whole is that, in general, these Ross Barnett Reservoir locations are quite safe to swim.  Heavy rains in the area had great impact on local water quality.  Please use caution immediately after rainstorms as sewer overflows, failing septic and stormwater runoff can contain high levels of bacteria.  
Picture
What's next?  Pearl Riverkeeper is expanding its citizen science water quality monitoring program and will begin conducting bacteriological monitoring at locations on the main stem of the Pearl River above and below the Ross Barnett Reservoir.  In addition to bacteriological monitoring, volunteers will be conducting Water Chemistry Monitoring which involves testing pH, dissolved oxygen, turbidity, hardness, alkalinity and temperature. 
The state of Mississippi has over 26,000 miles of perennial streams and rivers. For the state's 2016 Water Quality Assessment, MDEQ assessed only 11% of our waterways and stated that the status of water quality on the remaining 89% (23,568 miles) is unknown. Citizen science from our certified water quality monitors can help fill in the gaps and provide early detection of water quality issues in areas not actively monitored.

HOW CAN YOU GET INVOLVED?
  • Volunteer for our Clean Water Team
  • Text "PRKSWIMGUIDE" to 844-83 to receive water quality alerts by text message
  • Support our work financially by becoming a member  

Thank you to all of our volunteers, supporters, Swim Guide, MDEQ and Global Water Watch for making this inaugural year of Swim Guide a huge success!

Wetlands Value

7/9/2018

 
Picture
The proposed One Lake project would destroy 1,500 acres of Jackson-area wetlands that we will never get back. Wetlands are among the most valuable ecosystems on the plant. According to a recent study, the economic value of the ecological services provided by wetlands is $5,582/acre/year. 
-A bottomland hardwood swamp can remove the same amount of pollutants as a $5 million water treatment plant. 
-Wetlands function like natural sponges, storing water and slowly releasing it, reducing flood heights, allowing for groundwater recharge, and slowing the water's erosive potential. Maintaining only 15% of a watershed in wetlands can reduce flood peaks as much as 60%. Wetlands can reduce flood damage by $8,000/acre/year by absorbing stormwater. An acre of wetlands can store 1-1.5 million gallons of floodwater.  
-Two thirds of all fish consumed worldwide are dependent on wetlands at some stage in their cycle.
-The cost saving for removal of carbon from the atmosphere is $2 of damage prevention annually per ton of carbon removed. Wetlands are estimated to store between 81 and 216 metric tons of carbon per acre. 
-Wetlands are home to 31% of our plant species.
-Wetlands are some of the most biologically productive natural ecosystems in the world, comparable to rain forests. and coral reefs in their productivity and diversity of species.
-Up to 50% of North American bird species nest or feed in wetlands.

These wetlands belong to all of us and to our future generations, not to the One Lake developers.

Threatened turtles of the Pearl River and the One Lake project

6/29/2018

 
by Will Selman

​​The Pearl River system hosts two unique turtle species: the Ringed Sawback (Graptemys oculifera) and the Pearl Map Turtle (Graptemys pearlensis).  Neither of these species can be found anywhere else in the world… only the Pearl River system of Mississippi and Louisiana!  The Ringed Sawback was designated as federally threatened in 1986, while the Pearl Map Turtle was petitioned in 2011 to be listed under the Endangered Species Act.  Both turtle species are of conservation concern for a number of reasons mainly associated with alterations to their river habitat.  Alterations include construction of dams, channelization of rivers, and excess river sedimentation.  

Millsaps College students and I have been conducting surveys for the Ringed Sawback and Pearl Map Turtle over the last couple of summers in the Jackson area.  Our surveys are inclusive of the One Lake Project Area (i.e., where the lake will be constructed), and our surveys also include both upstream and downstream segments of the Project Area.  The data we have collected over the last couple of summers are in contradiction to many of the statements recently published in the Integrated Draft Feasibility & Environmental Impact Statement (hereafter, draft EIS) by the Rankin-Hinds Pearl River Flood Drainage and Control District. Below I highlight a few of our findings and compare them to the draft EIS.

Finding 1: The draft EIS states that “survey efforts have been limited and the extent of the [Ringed Sawback] population within the Project Area is not known at this time.” Contrary to this statement, our surveys have found that the Ringed Sawback can occur in great numbers upstream, downstream, and within the Project Areato be impounded by One Lake.  Based on our population surveys in this stretch, we have observed between 56 – 280 Ringed Sawbacks basking per river mile within the Project Area.  When we survey, we only count turtles basking on logs, and this count is not inclusive of the many turtles that may be underwater and unobservable during our surveys. Therefore, if we account for those that are unobservable, we estimate that the total Ringed Sawback population in the Project Area is likely ~1,200 – 2,500 individuals (including adults and juveniles).  

Finding 2: The draft EIS states that previous flood control projects in Jackson have “degraded habitat for Ringed Sawbacks and nesting habitat is almost non-existent.”  Indeed, the channelization and desnagging of the Pearl River has negatively impacted portions of the riverine habitat in the Project Area (mostly between Lefleur’s Bluff State Park and south of I-20).  But as mentioned above, our research indicates that a healthy Ringed Sawback population occurs where the One Lake Project is proposed.  Further, a recently published study indicates that the population north of Lakeland Drive is the most stable of five sites studied for the last 30 years, and the Lakeland population has increased in size since 2000; three of the other four study populations were declining (Jones 2017).
Contrary to the draft EIS, we also have observed direct evidence of significant nesting and successful reproduction of Ringed Sawbacks in the Project Area.  We have observed Ringed Sawback females nesting on sandbars in the Project area, seen many tracks on sandbars by nesting females, and nests destroyed by predators; all of these are indicative of suitable nesting habitat and a reproductively viable population.  During a survey this year, we observed that 27% of the basking turtles were hatchlings or juveniles, and this is indicative of exceptional recruitment in this stretch over the last couple of years.  It is unknown why reproduction has been so successful in this urban stretch of river, and it seems somewhat counterintuitive.    

Finding 3: The draft EIS states that the impacts to the Ringed Sawback population will be “minor in intensity and long-term in duration.”  For both turtle species that specialize in flowing Pearl River habitats, if a dam turns a flowing river into a stagnant lake, these riverine turtles will likely be lost over time.  I would consider such a change “habitat alteration”, a primary threat to the species outlined in the U.S. Fish and Wildlife Ringed Sawback Recovery Plan.  Impounding a river to form a lake is equivalent of taking a hardwood forest, cutting it down, and planting a row crop like corn; the habitat will be completely altered to something dissimilar to its current state.  We have observed in Crystal Lake and Mayes Lakes (old channels of the Pearl that are now lakes) that there are only a few Ringed Sawbacks compared to turtles that prefer non-flowing water, like Red-eared Sliders.  Similarly, if the One Lake Project is constructed, I suspect that some Ringed Sawbacks will likely “hold on” in the lake.  But over time, common turtles that are better adapted to the non-flowing water will replace Ringed Sawbacks.  Thus, turtles will still occur in the lake, but the rare species like the Ringed Sawback and Pearl Map Turtle will disappear over time, and the area will be colonized by cosmopolitan species.  Therefore, I would suggest that the impacts to this population will not be “minor in intensity.”  I suggest that it will be major in intensity and long-term in duration.

The draft EIS makes many assumptions about the Ringed Sawback, but it does not have any data to support these assumptions.  However, our survey data indicates that Ringed Sawbacks can occur in great abundance along the Project Area and recruitment/reproduction are better in this stretch than what has been observed in most Ringed Sawback populations.  Thus, if completed, the One Lake Project will be a major blow to this population and negatively impact the recovery of the species.
