The purpose of this program is to engage community groups for the installation of community accessible rain gardens and other water quality best management practices in Ramsey County. The goal is to install 6-12 storm water best management projects that will help protect and improve water quality of surrounding lakes. The installed practices will reduce an estimated 10 acre-feet of storm water runoff, 9 pounds of phosphorous, and 3 tons of sediment annually. Significant measurable outputs, with development of long-term partnerships, are primary objectives for this program.
Little Lake Johanna is not meeting state water quality standards due to excessive phosphorus. The Rice Creek Watershed District, in partnership with the City of Roseville, will improve the water quality of stormwater runoff into Little Lake Johanna through installation of an iron-enhanced sand filter. The Oasis Pond Iron-Enhanced Sand Filter Project will annually remove approximately 34 pounds of phosphorus from runoff to Little Lake Johanna annually. This is equal to nearly 20% of the needed load reduction as established by the Southwest Urban Lakes Total Maximum Daily Load Study.
Ramsey County, the most densely populated county in Minnesota, generates high levels of contaminated runoff from its impervious surfaces. When contaminants drain into abandoned and unused wells, it threatens the health of Ramsey County citizens who depend on groundwater as their main potable water source.
Ramsey County, the most densely populated county in Minnesota, generates high levels of contaminated runoff from its impervious surfaces, which can have damaging effects on both surface water and groundwater. Concerns arise when these contaminants drain into abandoned and unused wells, threatening the quality of groundwater, especially in drinking water supply areas, wellhead protection areas, or groundwater recharge zones.
The Ramsey Conservation District is partnering with the Vadnais Lake Area Water Management Organization, St. Paul Regional Water Service, and Ramsey County Parks and Recreation to restore and stabilize approximately 550 linear feet of streambank along the Sucker Lake Channel in northeastern Ramsey County with a cost effective critical area planting, replacing the existing mix of turf grass and asphalt streambank with a native vegetation planting.
