Capitol Region Watershed District and the City of St. Paul seek to improve the water quality of stormwater runoff to Como Lake in St. Paul and reuse stormwater to displace potable water use at the McMurray Fields complex within Como Regional Park. The project partners propose the construction of a stormwater reuse and infiltration system that will treat the stormwater volume equivalent of 1.1 inches over the impervious surface of the subwatershed, or 4.9 acre-feet. The drainage area to the proposed system is 130 acres, with 54 acres of impervious surfaces.
Project funding is requested to complete the second phase of an on-the-ground implementation project to restore function to the partially drained Rice Lake wetland, which will reduce the largest phosphorous tributary loading source to downstream Detroit Lake, a high value recreational lake. This wetland restoration nutrient reduction project was broken up into two (2) construction phases due to cost constraints, with the Phase 1- Upper Pool Restoration Area completed in November 2021 using a Clean Water Fund Grant (C21-4482).
The goal of the project is the reduction of nitrates in the groundwater by promoting and implementing best management practices and alternative management tools in the priority areas of Sherburne County. Practices included in the application are: Cover crops, irrigation water management , and nutrient management. Additional incentives included are for the Conservation Reserve Program. District Staff will also plant at least one acre of demonstration plots which will be highlighted at an annual field day.
This project strives to make further, substantial steps towards the sediment and nutrient reduction goals for Buffalo River Watershed District's (BRRWD) Mainstem and Lakes Planning Region and the objectives of the Buffalo-Red River Comprehensive Watershed Management Plan adopted in 2021.
This project will continue to protect and improve Valley Creek, a world-class trout stream located in the Valley Branch Watershed District. Stabilizing Ravine 2E, which conveys runoff from a 150-acre watershed directly into the main stem of Valley Creek, will prevent 7 tons of sediment from depositing in the creek and silting over trout spawning sites on an annual basis. It will also reduce the annual total phosphorus load to Valley Creek and the nutrient-impaired Lake St. Croix by 51 pounds per year.
West Indian Creek (WIC) watershed has been specifically mentioned in multiple plans as a location to target for protection and restoration. It is recognized for its' high conservation value forests, biodiversity , and rare species. WIC is one of 18 cold water trout streams in Wabasha County and approximately 3 stream miles have been restored by Trout Unlimited. WIC is currently listed as impaired for E. coli and mercury. However, the focus of our application is on sediment and nitrates.
