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.
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 (District) has determined that large impervious sites (like churches, commercial sites, and schools) are more economical for stormwater management retrofit projects than distributed small projects along roadways. The District began assessing church sites for retrofit opportunities in 2013 and will continue this effort in 2014. Church congregations have been receptive to partnering with the watershed district.
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).
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.
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.
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.
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.
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.
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.
The Rice Creek Watershed District (RCWD) will create a web-based, mobile-compatible public drainage system inspection and maintenance database. This database system will enable District staff to create and track maintenance requests and inspections from the field, including Geo-referencing locations requiring repair via a mobile device. The system will greatly reduce the time required to identify and log each maintenance request, enabling staff to inventory more miles of public drainage system yearly thereby identifying erosion problems more efficiently and thoroughly.
The Ramsey-Washington Metro Watershed District (District) has determined that large impervious sites (like churches, commercial sites, and schools) are more economical for stormwater management retrofit projects than distributed small projects along roadways. Analysis of the watershed land use indicates that large impervious sites are typically commercial properties (primarily retail), churches, and schools. The District began assessing church sites for retrofit opportunities in 2013 and will continue this effort in 2014.
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.
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.
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.
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.
To be able to manage resources in the Blue Earth and Le Sueur Watersheds into the future and have a positive effect on water quality, resource managers need high quality accurate data to support decision making of best management practice (BMP) implementation. Digital elevation data is a valuable resource for modeling water flow, however in its current state it cannot represent water conveyance through features such as roadways. These flow barriers limit the accurate use of data for recently developed targeting tools identifying BMP suitability and effectiveness down to the field scale.
At almost 4,000 acres, Trout Brook is the largest subwatershed in the Capitol Region Watershed District and the City of Saint Paul. The restored stream is part of the 42 acre Trout Brook Nature Sanctuary project, whose goal is to return the area back to some resemblance of its pre-industrialized valley of stream floodplain and wetlands. Monitoring results within the corridor show that phosphorus, sediments, bacteria, lead and copper are the pollutants of most concern.
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.
