2015 Year in Review • Average precipitation was similar to 2014 – BUT… – Snowmelt runoff was very small – Rainfall in 2015 was more evenly distributed – Annual precipitation is not necessarily a good indicator of runoff, P loading • ~25,000 lb. P delivered to Lake Mendota among the 4 major tributaries. • Trophic Index (P) for Lake Mendota was above desirable level. • P Loads at Fulton were ~ 110,000 lb.

Adaptive Management Cost Model Kyle Minks and Dave Taylor
YAHARA WINs ADAPTIVE MANAGEMENT STRATEGIC PLANNING WORKGROUP MEETING SEPTEMBER 10 TH 2015 Dane County Land & Water Resources Department Kyle Minks Land and Water Resources Scientist
IMPLEMENTATION MODEL Inputs Outputs • Practice phosphorus • Yearly costs reductions and lifespans • Yearly estimated • Staff time and costs revenue & cost share • Practice costs • Yearly total phosphorus reductions • Practice distributions • Yearly staff hours • Ramp up time
PHOSPHORUS REDUCTIONS • Identify practices that reduce phosphorus • Averages based on model runs • Lifespans • Based on design standards • Contract lengths
STAFF TIME AND COSTS • Time to plan, design, construct, and verify project completion • Large range in times • Applied a $60.00/hr rate for costs
PRACTICE COSTS • Estimated using • Dane County average costs • Adjusted NRCS cost share rates
PRACTICE DISTRIBUTION • Distribution by reach and year • Based on 2008 to 2012 data • Shift towards more structural practices
RAMP UP • Total overall phosphorus reductions • Rate at which each reach achieves its phosphorus goal • Yearly targeted phosphorus reduction
MODEL RESULTS
Intergovernmental Agreement (IGA) 2 Reviews by potential participants Final version to go out in mid-December Execution by end of 1 st quarter-2016 Frequently asked questions “hand out” to accompany the IGA District staff is available to attend meetings if requested
Some changes in the final version of the IGA Annual payments in two equal increments (Feb 28 th and June 30 th ) Updated modeling needed by September 1 st in order to be applied to subsequent years Credit if a municipality overpays in initial year(s) Unused funds returned at the end of the project Continuation language regarding 2016 project funding Executive committee has two additional “advisory” positions that are non-voting
Recovering Costs From IGA Participants
Adaptive Management Plan One plan for the watershed DNR review of draft plan Draft plan will be placed in WINS portion of MMSD website under “resources” Hope to receive conditional approval in 1 st quarter of 2016
