This feasibility study will produce strategies for wetland restoration and ditch hydrology changes to reduce the amount of phosphorus and solids that drain into Typo and Martin Lakes, the Sunrise River and St. Croix River. Total Maximum Daily Loads and other plans have identified this area as key for pollutant reduction, and the study will determine scope and effects of potential projects, allowing the district to prioritize those that will have the great impact on water quality.
This project will install nearly 800 linear feet of restored lakeshore with an emphasis on bioengineering techniques, native plants and locating buffers/swales at points of concentrated overland flow into Green Lake. By targeting properties that are eroding and/or with concentrated overland flow to the lake we will reduce suspended solids discharge by 16,697 lbs/yr and phosphorus by 1.3 lbs/yr.
This project will result in the installation of give water quality practices totaling 350 linear feet of restored lakeshore and 6,000 square feet of native plant stormwater management. By targeting properties that are eroding and/or with concentrated overland flow to the lake, pollutant discharge to the lake will be reduced.
Golden Lake does not meet state water quality standards due to high phosphorus levels. The proposed iron enhanced sand filter basin was identified in the Golden Lake Subwatershed Stormwater Retrofit Analysis to be one of the most cost effective remaining practices for reducing external phosphorus loads to Golden Lake. This project, paired with two previously installed upstream Best Management Practices, will achieve on average, 84% of the phosphorus reduction goal for the watershed.
Under the CREP partnership with USDA, 71 easements were recorded on a total of 4,365 acres to restore previously drained wetlands and adjacent uplands. The easements were accomplished with local implementation done by SWCD, NRCS and FSA staff within the 54 county CREP area and leveraged federal funds for both landowner payments and cost share for conservation practice installation.
The Clean Water Fund (CWF) and Outdoor Heritage Fund (OHF) were used together to secure easements on buffer areas. 84 easements have been recorded for a total of 1,441 acres and are reported in the output tables for the final report (acre total does not include Clean Water Fund acres). The total acreage from both CWF and OHF sources for recorded easements is 2,793.2 acres. Only the OHF acres are being reported in this final report to be consistent with the approved accomplishment plan.
The Mississippi River is currently listed as impaired for turbidity. Eroding riverbanks are one of the causes of this impairment. An inventory was completed in 2016 of riverbank condition along 5.8-miles of the Mississippi River that is within the City of Ramsey. In this inventory, ten severe to very severe eroding stretches spanning 27 private properties and 6,550 linear feet were identified. Cumulatively, these sites contribute 5,148 tons of sediment per year to the river.
