The Pope County Water Plan has identified surface water quality and erosion control as top priority resource concerns. These two priorities account for 33% of the phosphorus loading to Lake Emily. The Lake Emily Watershed Best Management Practices (BMP) Prioritization Project will provide GIS-based water quality analysis to assist the Pope Soil and Water Conservation District in determining effective locations for BMP implementation and will prioritize the areas from high to low for phosphorus, nitrogen, and sediment delivery from contributing runoff during rainfall events.
Pope Soil and Water Conservation District, partnered with Natural Resources Conservation Service staff and landowners, will install 22 targeted water and sediment control structures in two priority subwatersheds (Trappers Run and Minnewaska). These structures have the potential to reduce sediment load by 514 tons per year, and phosphorus by 440 pounds per year.
The City of Glenwood Water Quality Assessment & Best Management Practice Prioritization Project will include an assessment and analysis of approximately 1,796 acres affecting water quality and contributing runoff to Lake Minnewaska. By implementing this water quality analysis and assessment of the City of Glenwood and sub watersheds, a reducing pollutants by 1,287 pounds per year of phosphorus and 203 tons per year of sediment.
The Lake Emily Watershed BMP Targeted Implementation Project will provide funding for 48 water and sediment control projects and potential shoreline and riparian restoration. This work would address surface water quality sources identified in the water plan (Section 2-pg 11) including direct drainage from the Lake Emily sub-watersheds (070200050304, 070200050303, 070200050203, 070200050201, 070200050202) the Little Chippewa, and from upstream discharge between Lake Emily and Lake Minnewaska.
Pope SWCD has 9 motivated landowners with 21 WASCOBs, 1 lined waterway, and 1 shoreline restoration in two priority sub watersheds (Trappers Run and Minnewaska). Based on averages calculated from recently constructed WASCOBs in the West Central Area II these projects have the potential to reduce TSS by 518 T/year, and 446 lbs./year of TP. This project will provide a secondary benefit to improve downstream water quality to Lake Emily. The project will result in meeting 99% of the Lake Emily TP lbs/yr.
Lake Emily is a high priority recreational lake in Pope County and is currently not meeting state water quality standards due to high phosphorus levels. This project will provide funding for 26 water and sediment control projects with potential shoreline and riparian restoration projects. This work will address surface water quality sources including both direct drainage and upstream discharge. Collectively, these projects have the potential to annually reduce sediment and phosphorus leaving the field which will directly address 15% of Lake Emily's phosphorus reduction goal.
