4 PLANNING MEETING LAKE MANAGEMENT PLAN FOR PIGEON LAKE January 23, 2014 PREPARED BY: Mark Kordus Dale Buser James Scharl

5 LAKE MANAGEMENT PLAN FOR PIGEON LAKE EXISTING PLAN HOW DO WE DO THIS? WHY ARE WE DOING THIS? LAKE ECOLOGY MANAGEMENT OPTIONS & TRIGGERS WHAT WILL THE REPORT COVER?

6 EXISTING LAKE MANAGEMENT PLAN Current plan adopted in 2006 Recommended focus on AIS management 2,4-d treatments for Eurasian water-milfoil and/or endothall for curlyleaf pondweed with no goals for AIS reduction Limited mechanical harvesting Potential water-level manipulation Dredging WI DNR recommends APM plan updates every 5 years Captures new data and updates current condition of plant community Needs to be updated to allow for large scale management permit (greater than 10 acres) Plan must be current and reviewed by WDNR technical team to be grant eligible

7 WHY ARE WE DOING THIS? Better overall management strategy for Pigeon Lake Prevent the spread of Aquatic Invasive Species Develop baseline and review previous data to determine the effects of the chosen management options Evaluate effects over time both natural or man-made To have a systematic approach in place, with measurable outcomes Bring awareness to the public of the benefits and problems associated with Pigeon Lake, as well as possible solutions Put the District in the best possible position through a well written plan with specific action items and measurable outcomes to be able to obtain grant funding

8 HOW DO WE DO THIS? Research Existing Data WDNR files, past projects, lake group data Baseline Data Why are we doing it and what will it tell us? Document changes since last survey/plan Document health of the lake through survey metrics Look at the history of what's happened on the lake Public Opinion Survey Gauge public s perception of Pigeon Lake Find out where we want to go from here What are the issues of concern on Pigeon Lake? Explore potential lake management alternatives Water quality Collect existing data to determine Trophic Status Gauge of a lake s productivity over time Look for historic changes in water quality

9 Watershed Analyses Watershed Includes all land surface area draining into the lake Land use within the watershed affects water quality Nutrient input from runoff & storm sewers Increased nutrient input can lead to increased eutrophication or lake aging Modeling available based on land use WiLMS Wisconsin Integrated Lake Management Suite LEAP Lake Eutrophication Analysis Procedure Both allow for nutrient modeling based on current & predicted future land use Phosphorus the main nutrient for watershed impact Allow for a what if? analysis and comparison

10 What s in the Plan? Prepare Comprehensive Lake Management (CLM) Plan Summarize lake data (watershed and water quality) Evaluate available lake management techniques Past successes and failures in WI, University Research, Neighboring States, Federal Agencies Triggers for management options & goals Provide the public an opportunity to give input Select CLM options specific to a lake s needs and public desires Assemble a public opinion survey to gauge lake user issues and concerns Data from surveys and public meetings complied and used in creation and guidance of plan document

11 CURRENT WATER LEVEL ISSUES Operational Water Levels at the Dam Threshold Water Elevations Water Quality and Sediment Transport ---The Affect of Outlet Design Management Goals and Outlet Design/Operation are Linked Water Balance Life-Cycle Critical Habitat Support, Ingress and Egress Symbiotic Opportunity? Decrease Phosphorus Flux, Reduce Plant Available Nutrients in Lake, Increase Volume of Water Tangibly Contributing to Fishery, Enhance Downstream Water Quality and Fishery?

12 CURRENT SEDIMENTATION ISSUES Sedimentation Challenges and Potential Solutions Prioritized Goals with Clearly Defined Expectations Group Discussion to Help Provide Focus Different Areas, Different Goals/Expectations Sediment Sources and Transport Mass Balance Approach Sediment Thickness, Volumes, Properties Sustainability --- e.g., Cost and Effective Life of Remedy

13 Brady & Fairway Lakes Possible sediment control basins Current ecological significance of Brady and Fairway Lakes Identify desires, goals, expectations group discussion Increasing water depth (targeted dredging) and lessening sediment delivery to Fairway Lake potential for unique habitat conditions? Brady Lake open forum

14 CURRENT AQUATIC PLANT ISSUES Aquatic Plant Levels Currently dense and growing at nuisance levels Hampering recreation and enjoyment of the lake Enhanced by nutrient inputs from watershed Limited management options Increasing costs to keep in check

15 CURRENT FISHERIES CONCERNS WDNR is Putting Finishing Touches on a Fishereis Report Review When It Becomes Available Secondary Effects of Sediment and Dam Management Activities Review Full Life Cycle Habitat Needs for Target Species Lake is Particularly Vulnerable to Invasives Many Boat Launches, Dam is First Barrier

16 WHY ARE AQUATIC PLANTS GOOD? Benefits of Aquatic Plants Fish & Wildlife habitat, food Erosion Control Nutrient uptake prevents algae blooms

17 INVASIVE AQUATIC PLANTS Aquatic Invasive Species (AIS) Introduced from other regions Lack of natural controls Grows earlier/longer than native species Can out-compete native aquatic species & grow to nuisance levels

18 AQUATIC PLANT ECOLOGY - AIS Eurasian Watermilfoil(EWM) AIS that is Native to Europe & Asia Spread by boats / trailers coming from infested waters First found in Wisconsin in 1960s Hybrids are becoming bigger issue Confirmed in Pigeon Lake in 1993

19 AQUATIC PLANT ECOLOGY - AIS Curly-leaf Pondweed (CLP) AIS that is Native to Europe & Asia Spread by boats / trailers coming from infested waters First found in Wisconsin in 1960s Confirmed in Pigeon Lake in 2012

20 PLANT MANAGEMENT OPTIONS Aquatic Plant Management Options Mechanical harvesting Immediate relieve, much like cutting your grass Can be used for navigational access only Non-selective & depth limited typically > 4 Can spread certain undesirable species Permitting required Water level drawdown Done over winter to freeze root stock of EWM -weather dependent Not selective, affects all plants, some positive some negative Some species more susceptible. Can offer good control of EWM Requires public hearings and permit and potentially lost revenue Herbicide AIS management If done properly, can be selective, many times lowest cost option Use depends on desired management goals Permitting required

21 PLANT ISSUES OTHER OPTIONS Bottom Barriers Work well to control plant growth Difficult to permit Dredging Removes native and invasive plants temporarily Very expensive Difficult to permit Biocontrols Milfoil Weevils & Grass Carp Milfoil weevils Can offer good EWM control They are expensive & no longer commercially available Grass Carp offer good aquatic plant control Not permitable in Wisconsin by WDNR

23 WHAT WILL THE REPORT COVER? Executive Summary Watershed Aquatic Plants Water Quality Sedimentation / Dredging Changes Over Time Conclusions and Management Options Recommended Action Plan & Triggers

24 NEXT STEPS? Preparation of a public opinion survey Will be available February 4, 2014 for 30 days Hard copy s available through Lake District Or on-line at Survey Must be completed or returned prior to March 6, 2014 Survey results will be incorporated into plan guidance Watershed Evaluation & Modeling February 2014 Water Quality Sampling summer of 2014 Aquatic Plant Point Intercept Survey July/August 2014 Draft Plan available for review/comments Oct./Nov Final Plan Presentation to WDNR Dec./January
