1 Marinette County Lower Peshtigo River Watershed Management Plan MARINETTE COUNTY S EXPERIENCES CREATING A NINE KEY ELEMENT PLAN

2 Plan Goals Learn more about the biota, environmental health, and human health risks in the watershed Reduce NPS pollution impacts on human health Deal with other environmental stressors in the watershed Minimize the risk of acute manure and runoff events and the amount of Phosphorus reaching Green Bay Provide information in support of plan goals; make the connection between land use and environmental quality Improve communication with and between producers; publicize progress and increase acceptance; improve BMP operation and maintenance

13 Spreadsheet Tool for Estimating Pollutant Load (STEPL) tool calculates nutrient and sediment loads from different land uses and load reductions resulting from implementation of various BMPs. It computes watershed surface runoff; nutrient loads, including nitrogen, phosphorus, and 5-day biological oxygen demand; and sediment delivery based on various land uses and management practices. The annual sediment load (sheet and rill erosion only) is based on the Universal Soil Loss Equation and the sediment delivery ratio. Sediment and pollutant load reductions are computed using known BMP efficiencies.

This equates to Phosphorus loads of approximately 2.34 pounds of per acre. For sediment, the same Pre-Project acres will generate a load of 0.23 Tons per acre. Upon project completion, the total cropland and feedlot phosphorus load will be reduced by 20,440.1 pounds, equating to an estimated 1.6 pounds per acre. For sediment, the estimated Post-Project load per acre is 0.15 Tons per acre.

15 Figure Planned Activities and Schedule (Plan Element 6 and 7) Goal Activity LWCD Partners and/or Funding Sources Milestone(s) Time Frame Prevention, control and eradication of Exotic Invasive Species WDNR, WRISC, NRCS, Local Gov ts One aquatic, and one terrestrial project per year 2016 to 2026 Deal with other environmental stressors in the watershed Prevent and/or repair fish passage problems Proper Culvert Installations Repair blockages USFWS, Local Gov ts Installation Workshop One per year 2019, 2023 As resources are obtained Restore wetland habitat, especially Northern Pike spawning and nursery areas WDNR, NRCS, USFWS, GLRI One project per year As willing landowners and funding are found

16 What I learned Get with the plan approval folks earlier than I did Look at approved NKE plans from similar counties, but not too closely Know what you don t know Don t be afraid to ask for help Models are only as good as the data you have put into them

17 Any questions?

18 Plan requirements 1. Identification of impairment causes and pollutant sources. 2. Estimate of the load reductions expected from management measures. 3. Critical area descriptions and the management measures needed to achieve element 2 load reductions. 4. Technical and financial assistance needed, costs and/or sources, and authorities relied upon. 5. Information and education component to enhance public understanding of the plan and encourage participation.. 6. A reasonably expeditious implementation schedule for management measures identified in this plan. 7. A description of measurable milestones for determining whether management measures are being implemented. 8. Criteria to determine loading reductions are being achieved and substantial progress is being made. 9. Component to evaluate the implementation effectiveness, measured against element 8 criteria.
