The Cannon River Watershed is a diverse watershed from the standpoint of topography, land use, and land cover, but a central issue of concern is increased sedimentation and turbidity within the river. One of the best ways to keep sediment from entering the Cannon River is to install vegetative buffers on the smaller tributaries in the upper reaches of the watershed. This project is important as it aims to help identify strategic locations where buffers are needed and to assist landowners to install buffers that will directly help reduce sedimentation within the watershed.
As the City of Wadena is being re-built after an EF4 tornado, it has become evident that more needs to be done to reduce runoff by retaining or diverting stormwater. The purpose of this project is to provide subgrants to citizens to install various conservation practices on their properties including grassed waterways, rain gardens and tree plantings. Through this subgrant program the citizens of Wadena will have a greater understanding of the importance of stormwater management.
Lake Bronson State Park is one of only a handful of state parks in the Northwest corner of Minnesota. The Friends of the Lake Bronson State Park met with Watershed District staff to explore how to improve the water quality of the lake. The lake is subject to sediment and nutrient loading from several upstream ditches. A significant algae bloom during July of each year, at the height of the seasonal use of the lake, is most likely due to the current inflow conditions.
The Straight River runs through Owatonna and is considered a priority water resource for the city. Untreated stormwater from city roofs, streets and parking lots are jeopardizing the water quality of river. Through this project, the city will install four rain gardens in city parks that will capture and rapidly absorb stormwater runoff from streets and driveways. The implentation of these rain gardens throughout the city will reduce the volume of stormwater entering the Straight River.
The 400-mile stretch of the Mississippi River from its headwaters at Lake Itasca to Morrison County near Little Falls is the focus of this project. Working in cooperation with the eight member counties, this project will develop implementation plans and strategies geared specifically for the Mississippi River and incorporate them into the individual County Comprehensive Local Water Plans. These recommendations will be for specific strategies, often crossing county boundaries for implementation.
This project is a partnership with Kittson County, the Joe River Watershed District and the Two Rivers Watershed District to install vegetative filters, buffers and erosion control practices along the Red River of the North and several major tributaries within the county.
This project will provide land and water managers in the Red River Basin with data and online tools to prioritize actions on the landscape that achieve water quality objectives identified in local and state plans. This will help identify strategically important locations for implementing erosion control and water management practices. Standardized watershed-based data products will be integrated into a web-based planning tool which will be added to the Red River Basin Decision Information Network (RRBDIN) being developed as part of the Red River Watershed Feasibility Study.
A large portion of Wadena County has been identified as having a high or moderate probability of elevated nitrate concentrations. With almost all of the residents in Wadnea County getting there drinking water from groundwater sources, this issue is a top priority to the county. Through this project, nitrates and other water soluble contaminants leacing into sensitive sand plain aquifers will be reduced by providing cost-share incentives to encourage irrigation producers to convert high or medium pressure irrigation systems to low pressure systems.
The Greater Blue Earth River Basin is a large area within the Watonwan, Le Sueur, and Blue Earth River watersheds. Recent research by University of Minnesota, the National Center for Earth Dynamics, and others has found this basin to be the largest contributor of sediment to Lake Pepin.
The Greater Blue Earth River Basin Alliance (GBERBA), a nine County/SWCD JPO has identified buffers as a basin priority. This initiative will work towards the goal of identifying all DNR protected shoreland in the GBERBA counties without a 50 foot vegetative buffer. Buffer strips protect surface and groundwater from a multitude of pollutants. During stormwater run off events buffers can remove between 50 and 100 percent of nutrients, pesticides, pathogens, and sediment. The estimated sediment reduction for this project is 756 tons per year prevented from entering our waters.
This project aims to significantly reduce the amount of sediment transfer from eroding bluff areas to Seven Mile Creek during spring snowmelt and rain events throughout the year. This will be accomplished by installing and maintaining drop structures and reinforcing the existing spalsh pool at the outlet pipe without destabilizing the surrounding bluffs. When applied in tandem, this project will reduce the peak flow rate to ravine areas while shielding and protecting the bluff itself from eroding.
