Ramsey-Washington Metro Watershed District (RWMWD) will improve water quality in Casey Lake and ultimately Kohlman Lake through the installation of approximately 25 rain gardens on priority properties identified as part of the Casey Lake Urban Stormwater Retrofit Assessment completed by Ramsey Conservation District (RCD) in 2011.
The Ramsey-Washington Metro Watershed District (RWMWD) is responsible for the protection and restoration of the water quality of 20 lakes and 5 creeks within its boundary. Permit and voluntary cost share programs serve to slowly redevelop the watershed to the benefit of these water bodies. However, additional projects are needed- not only to implement green infrastructure in areas that need extra restoration and protection, but also to foster new relationships between citizens and the RWMWD to rally together in a common goal to the benefit of their water resources.
This project will install an iron enhanced sand filter (IESF) to restore water quality in Golden Lake. Golden Lake is within a fully developed area of the Twin Cities, surrounded by residential land use, and the focal point of a city park. The IESF will achieve 11% of the phosphorus reduction (21 lbs/yr) required for Golden Lake to meet State water quality standards, as identified in the approved Total Maximum Daily Load (TMDL).
Lake George is the premier recreational lake in Anoka County with above average water quality, a vibrant fishery, and a large regional park and beach that is among the most utilized in the county. Located in northwestern Anoka County within the Upper Rum River Watershed Management Organization (URRWMO), the Lake George Improvement District (LGID) was formed to tend to the lake's diminishing water quality and problematic invasive species.
Past and current monitoring data has shown Ramsey County's Lambert Creek has high levels of total phosphorus (TP), anywhere from 0.14 mg/L to 0.30 mg/L, which is above the proposed State standard of 0.10 mg/L for streams in the Central Region.
This Oak Glen Creek stormwater pond expansion and enhancement using an iron enhanced sand filter (IESF) is a partnership between the Anoka Conservation District (ACD) and a private company to protect a downstream corridor stabilization and improve the quality of stormwater discharged to the Mississippi River. Very little stormwater infrastructure currently exists in the 573 acre Oak Glen Creek subwatershed, and it discharges 147,519 pounds of sediment and 353 pounds of phosphorus to the Mississippi River annually.
Ramsey County has 3,500+ acres tied to 358 faith organizations and 304 schools. On average, these properties contribute 1 billion gallons of stormwater runoff, 3,000 lbs of phosphorus, and 1,000 tons of sediment to our local water bodies. The Ramsey Conservation District (RCD), working with community partners and Watershed Districts/Water Management Organizations, will install 6-12 stormwater best management projects that will help protect and improve water quality of surrounding lakes.
The purpose of this program is to provide cost share funding to community groups for the installation of community accessible rain gardens and other water quality projects in Ramsey County. The Ramsey Conservation District (RCD) in partnership with local property owners and Watershed Districts/Water Management Organizations will install 6-12 stormwater best management projects that will help protect and improve water quality of surrounding lakes, streams, rivers, and wetlands.
Capitol Region Watershed District (CRWD), in partnership with the City of Roseville, will construct a volume reduction/capture-reuse irrigation facility below the Upper Villa Park Softball field in the City of Roseville. This project will protect Lake McCarrons and the Villa Park Wetland System (VPWS) by reducing runoff volumes and the pollutants associated with urban stormwater such as Total Phosphorus (TP), Total Suspended Solids (TSS), heavy metals, and petroleum products among others.
Capitol Region Watershed District is partnering with St. Paul Public Schools to implement a variety of highly visible Best Management Practices at Central High School that will improve the quality of stormwater discharged to the Mississippi River. A tremendous amount of sediment is discharged from the school annually due to the large impervious areas and lack of vegetation. Implementing the projects will reduce sediment by 86% and phosphorus by 90% over the target area annually.
Wakefield Lake is in the Ramsey-Washington Metro Watershed District (RWMWD) and is impaired for excess phosphorus. Through the Wakefield Lake TMDL process, implementation activities have been identified which include partnerships with the City of Maplewood to install BMPs in the watershed to directly benefit Wakefield Lake. RWMWD has researched, monitored and field tested the use of spent lime for stormwater quality treatment.
Capitol Region Watershed District will partner with local organizations and private landowners to implement a variety of cost-effective Best Management Practices in the East Kittsondale subwatershed. The urbanized condition of the 1,860 acre subwatershed results in an estimated 1,500 pounds of phosphorus, over 470,000 pounds of sediment, and significant concentrations of bacteria associated with that sediment being sent untreated to the Mississippi River each year. Those pollutants have contributed to several impairments within the river.
This project will continue collaboration with faith organizations in priority areas to implement stormwater volume reduction retrofit projects. Priority areas are defined as areas with limited to no stormwater treatment before reaching a water body and/or areas that drain to an impaired or at risk water.
Ramsey County is the smallest, most densely populated county in the state of Minnesota consisting of primarily urbanized land use. Ramsey County's water resources provide the industrial base, drinking water, and recreational opportunities for over one-half million people on a daily basis. The major environmental problems that Ramsey County lakes and streams face can be traced to the effects that urbanized land use has on these natural resources.
