19 The Wisconsin River Basin (WRB) Water Quality Improvement Project

20 Project Framework = Total Maximum Daily Load TMDL A TMDL answers the following questions: How much is the existing pollutant load? What is the contribution from each source? How much does pollution need to be reduced in order for waterways to achieve water quality standards? The Framework for Wisconsin River Basin Water Quality Improvement Project How will the pollutant load reductions be achieved?

21 Why develop a TMDL? Baseline Pollutant Load Does not meet water quality standards Total Maximum Daily Load Meets water quality standards

22 Developing a TMDL Baseline Pollutant Load? TMDL Load What is the magnitude of the Total Maximum Daily Load?

23 Developing a TMDL Baseline Pollutant Load??? How will the load be apportioned among sources?

24 WRB Total Maximum Daily Load (TMDL) Each subwatershed is assessed for: Background Load Naturally occurring from wetlands, forests Load Allocation Runoff from the landscape Load Allocation TMDL Waste Load Allocation + + Margin of Safety Waste Load Allocation Municipal Wastewater Industrial Wastewater Permitted Municipal Storm Sewer Systems CAFO Production Areas

25 WRB Water Quality Improvement Project Past, Present and Future Unsuccessful Funding Proposals 2008 First Pontoons and Politics State Legislature appropriates $235,000 (FY 2015) Water Quality Data Assessment Watershed & Reservoir Modeling Draft/Final TMDL Petenwell Castle Rock Comprehensive Management Planning State Legislature appropriates $750,000 over 5 years Comprehensive Basin Monitoring Basinwide Land Use & Land Management Mapping TMDL Implementation Allocation Development

27 WRB Water Quality Improvement Project How do we get to clean water. and who is responsible?

30 TMDL Implementation Wasteload Allocations How?. TMDL waste load allocations are incorporated into permits Municipal and Industrial Wastewater Permitted Municipal Storm Sewer Systems CAFO Production Areas (zero allowable discharge) Who? DNR sets limits based on allocations Permitted facilities implement limits

31 TMDL Implementation Nonpoint Source How? Establish partnerships to implement best management practices on the landscape Fair Share Everyone does what they reasonably can Targeting Use available resources to put extra effort towards high loading watersheds/areas Who? County Staff Agricultural producers Agricultural organizations Conservation Organizations Crop Consultants Citizens/Groups DNR/DATCP NRCS

32 What Can Citizens Do? Get Involved in Land and Water Resource Planning Get a copy of your county plan and see what it says about issues important to you! Become a planning committee member Get involved in local lake planning and management Encourage your county to apply for grants TRM Lake Protection River Protection Join your local Lake or Watershed group Get involved in volunteer citizen monitoring Ask yourself, what is my fair share? What can I do personally?
