THE PARTNERSHIP ROADMAP <br />To develop the Roadmap, MCWD led a subwatershed <br />assessment, funded by a grant from the Board of Water <br />and Soil Resources, to integrate resource needs and land <br />use plans for a regional understanding of the issues, their <br />drivers, and potential strategies to restore the system. <br />The Roadmap identifies capital project opportunities to <br />generate significant water resource benefits for the region. <br />WATER QUALITY BENEFITS <br />The partners identified 34 project opportunities that would provide measurable water quality <br />improvements. These projects are estimated to achieve the nutrient load reductions required to <br />remove Wolsfeld Lake, Long Lake, and Tanager Lake from the state’s impaired waters list. Holy <br />Name Lake and School Lake may require additional biological management to meet state standards. <br />THREE-TIERED STRATEGY <br />Retrofit three stormwater <br />ponds and create additional <br />treatment of stormwater <br />upstream of Nelson Lakeside <br />Park in Long Lake to enhance <br />the system’s effectiveness. <br />Implement 19 landscape <br />projects to reduce external <br />nutrient loading, including <br />stormwater management, <br />streambank stabilization, <br />and wetland restoration. <br />Administer alum treatment <br />and biological management <br />to address internal nutrient <br />sources within the system, <br />following the reduction of <br />external nutrient sources. <br />The projects are organized into three implementation categories. Regional treatment projects <br />are prioritized in the near term to cost-effectively address external nutrient sources and treat large <br />drainage areas in the subwatershed. Localized landscape projects and in-lake management will <br />complement regional treatment as funding and partnership opportunities emerge over time. <br />REGIONAL TREATMENT LANDSCAPE PROJECTS IN-LAKE MANAGEMENT <br />Holy Name <br />School <br />Wolsfeld <br />Tanager <br />Long <br />Required Nutrient Reducation (lbs.)Estimated Nutrient Reduction (lbs.) <br />Explore the full Roadmap on MCWD’s website: <br />minnehahacreek.org/long-lake-creek-roadmap <br />INITIAL ROADMAP IMPLEMENTATION <br />MCWD and the City of <br />Long Lake have secured <br />grant funding to conduct <br />feasibility and design work <br />for a regional stormwater <br />treatment project at this <br />city park to reduce runoff <br />volume and approximately <br />47 pounds of nutrients to <br />Long Lake annually. <br />HOLY NAME WETLAND BANK <br />This partnership between the City of Medina, private <br />landowners, and MCWD aims to restore 19 acres of wetland <br />and buffer as part of a residential development. The project <br />will increase flood storage, reduce nutrients to Holy Name Lake, <br />improve wildlife habitat, and generate wetland bank credits. <br />COUNTY ROAD 6 <br />POND RETROFIT <br />Retrofitting this MCWD- <br />owned stormwater pond <br />in the City of Orono will <br />improve water quality in <br />Long Lake by reducing <br />an estimated 67 pounds <br />of nutrients to the lake <br />annually. Construction is <br />planned for early 2025. <br />HOLBROOK PARK <br />STORMWATER TREATMENT <br />Partners are already advancing three projects from the Roadmap, one in each of the three cities. <br />These include two regional treatment projects that provide the greatest nutrient reductions and <br />one landscape project that will be implemented as part of a private development opportunity. <br />157
