Data supports drawdown

Recent research reflects concepts in understanding lake phosphorus and changes in their 'state'. 

Vitense, K., M.A. Hanson, B.R. Herwig, K.D. Zimmer, and J. Fieberg. 2019.

Predicting total phosphorus levels as indicators for shallow lake management. Ecological Indicators 96:278-287. This recent study suggests that phosphorus levels can determine the potential success of shallow lake management such as drawdowns. Little Rock Lake total phosphorus (TP) levels were once as high as 600 parts per billion (ppb) in 2006. Thanks to aggressive efforts by both Morrison and Benton county Soil, Water Conservation Districts, working with cooperative agricultural producers, that level is now down to less than 130 ppb in 2017. The study used classifications of TP of less than 50 ppb and greater than 50 ppb. Some lakes higher than 350 ppb were found to have a permanent turbid state, while lakes with less than 50 ppb were in a permanently clear state. Little Rock Lake sits at the lower end of the spectrum of what is known as a "bi-stable state". As suggested in the study " These estimates provide valuable information to managers becausea lake’s TP level in relation to the tipping points has implications for identifying effective management actions. Clear lakes with TP levels consistently below the lower tipping point are highly resilient, and management efforts for these lakes should typically focus on watershed and shoreline protection. Highly dynamic lakes with TP levels frequently in the bistable region are those for which active in-lake management, such as water level drawdowns or fish removal, is most sensible."  

Other drawdowns happening around Minnesota

 Another common question was asked during the process of planning: Has a drawdown like this been done before anywhere? Quite a few have been done around Minnesota, however, each system and situation is unique. In the early 2000's, the Mississippi River near the Iowa state line had a few pools that were drawn down to improve waterfowl and fish habitat. Lake Orono (near Elk River) had a winter drawdown done to help an excavation project and minimize curly leaf pondweed. Lakes Freeborn, Fulda and Long in southern Minneosta have had drawdowns for various purposes with impressive results. Major water clarity improvements were observed, with increases in valuable emergent plant growth as well. Lakes Ocheda and High Island, also in southern Minnesota, are in the process of planning drawdowns in the near future. Interestingly, many well known lakes north central Minnesota, are currently experiencing a drought cycle. This lower water level has allowed plants like wild rice, bulrush and cattail to expand in the shallow flats. This validates the presumption that a drawdown is intended to simulate a drought cycle.

New Board of Director and Membership Meeting Schedule

Board of Director and Membership meetings will resume in April of 2019 for the summer (second Saturday of each month). There will be no BOD or Membership meetings this winter. As always, stay tuned and watch the news section of the web site, the newsletter and facebook for updates.    

Community Meeting Regarding Delayed Drawdown: Friday, August 3, 2018 @ 7:00 PM. Lake View Center.

The community is invited to a meeting regarding the drawdown delay. A presentation and Q / A will follow. 

2018: Drawdown Delayed

The Little Rock Lake Association a volunteer non-profit organization dedicated to restore and maintain the Little Rock Lake Watershed was advised by the Minnesota Department of Natural Resources that the planned drawdown for August 1st, 2018 will be delayed. 

The drawdown of Little Rock Lake and the Mississippi River north of Sartell will be postponed for a year due to a need for a further review to satisfy federal requirements, according to the Minnesota DNR. Because the Sartell dam that would be opened to allow the drawdown is a hydropower dam overseen by the Federal Energy Regulatory Commission (FERC), a thorough review of potential impacts to cultural and historical resources is required before the project can proceed. Due to miscommunications, the historical-cultural review that was done did not meet strict federal requirements. 

Large projects always have many moving parts in them. Federal review of projects (Due to FERC) becomes even more complicated. The Sartell Dam is a FERC regulated dam. As such, any changes in operational procedure require extensive Cultural resource review. The State Historical Preservation Office (SHPO) needed unanticipated, additional consultation from several cultural resources, for the project to go forward. While all approvals were met for a normal state run project, the federal process is lengthier and some levels of miscommunication were also present. As a result, the drawdown for 2018 has been postponed until the same time frame (August 1-September 15) in 2019. This will allow FERC, Eagle Creek, MNDNR, SHPO Little Rock Lake Association and Benton SWCD to obtain adequate review of this project for 2019. 

“For a couple years now, a lot of agencies and people have been working toward the goals of better water quality and habitat that this drawdown would bring about, so this delay is certainly disappointing,” said Eric Altena, the DNR fisheries supervisor who has spearheaded the project. “It’s only a temporary setback, though. We’ll be back next summer with everything in order and set to go for the same timeframe.”There are efforts being made to still try and accomplish some portions of the project. However, plans have not been solidified. We will do our best to keep residents and users informed. 

Your volunteer Little Rock Lake Association Board of Directors remain committed to better watershed health and will continue to be involved in the drawdown and advocate for Little Rock Lake. Please watch the Little Rock Lake Association web site and Facebook for continued updates.

Results of the Drawdown hearing  

We had a great turnout for the drawdown hearing March 28th, More than 150 people showed up to learn the latest information and ask pertinent questions about the process, funding, plant growth and fish concerns, among several others. A summary of the most common questions and concerns can be found on the drawdown website www.mndnr.gov/sartell-drawdown Video clips from the meeting are available here on the Little Rock Lake Association Facebook Page.The cooperative project with Benton County Soil, Water and Conservation district (SWCD), Little Rock Lake Association, Eagle Creek Energy and MNDNR has been described in the news several times and will take place August 1-September 15 - 2018. Please feel free to contact Eric Altena using the information below if you have further questions.

2018 Drawdown

Little Rock Lake-Sartell Pool Drawdown Project Information

A proposal to consider a summer drawdown at Sartell Dam 2018 

Original Article

Recent meetings with Eagle Creek Energy suggested we may need to consider some alternatives to a system-wide longer term drawdown. Maintenance requirements, loss of significant revenue and complexities with FERC licensing made it worthwhile looking at other options. One of which may be operation of the dam at a lower level (IE 2ft below full pool instead of 3ft). Another potential option may be a temporary coffer that would isolate the lake using water inflatable tube dam. Several manufacturers make the products. A potential option may include the use of a temporary dam and pumping after a short (4-5 day) drawdown for a longer term drawdown, within Little Rock Lake and the channel area. In either case, options are available and funding can be acquired to make the project happen. We will be working closely with Little Rock Lake Association and Benton SWCD to put a grant proposal in for the project timeline of Summer 2018.
