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).
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
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.
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.
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.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
The lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Ten of these small communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly into the environment, surfacing sewage, or have sewage contaminating groundwater.

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.
The Cannon River is a designated Wild and Scenic River that originates in Rice County and joins the Mississippi River 120 miles downstream near Red Wing. The Upper Cannon, which encompasses 29% of the entire watershed, has been identified as a priority subwatershed.
