Recent efforts by Carver County Water Management Organization Staff have centered on removing point sources of bacteria in both Bevens and Carver Creeks. These efforts have shown improvement in water quality; however the creeks are still above the state standard for E. coli. Early results from field surveys have pinpointed areas where livestock have uncontrolled access to streams. Five sites over a twenty mile stretch of Bevens Creek have shown evidence of livestock access to streams and associated damage to streambanks.
In 2002 and 2004, the Minnesota Pollution Control Agency listed Bluff Creek for turbidity and biological integrity. A Total Maximum Daily Load report and implementation plan were finalized and approved in 2013. This project was identified as a high priority site for culvert restoration and bank repairs.
The Burandt Lake Stormwater Reuse System (BLSRS) project will install a water reuse system to capture untreated storm water and reduce pollutants entering Burandt Lake. This collaborative project with Carver County, Carver County Soil and Water Conservation District (SWCD), City of Waconia and Independent School District 110 will retain and reuse an estimated 48% of the annual storm water runoff (1.25 million gallons) currently generated from eight acres of adjacent residential neighborhoods.
This project will increase the ability of the Carver County Water Management Organization (CCWMO) to approach local community partners and fund projects that treat stormwater runoff at the source instead of treating stormwater downstream at a regional pond or through other large scale best management practices (BMPs).
The Carver County Planning and Water Management Department (PWM) has an active well sealing cost share program. Following the adoption of the updated County Groundwater Plan in February of 2016, the Carver County Board of Commissioners moved to accelerate the program to encourage landowners to seal abandoned wells. Carver County is looking to supplement existing funds, as demand is expected to increase. With this additional funding, it is the goal of Carver County PWM to seal an additional 15 wells county wide.
The purpose of this project is to install prioritized and targeted best management practices on the Carver County Ditch #6 drainage system that drains directly into Bevens Creek. Bevens Creek does not meet state water quality standards for sediment. The goal of the project is to install 6 grade stabilization structures, 5 grassed waterways, and 2 water and sediment control basins that have been identified through GIS LIDAR applications and field verified along with landowner support.
Carver County has identified water quality improvement of Carver, Bevens and Silver Creek as a water management priority. This project will identify storage or wetland restoration sites that are highly effective at reducing pollutant loading to downstream impaired waters using high-resolution Light Detection and Ranging (LiDAR) data and Geographic Information System (GIS) processes. The watershed landscape has been highly modified for agricultural production land development; less than 50 percent of pre-settlement wetland acres remain in Carver County.
The downtown Chanhassen stormwater best management practice (BMP) retrofit assessment project will reduce watershed phosphorus loads to Rice Marsh Lake and improve the water quality in downstream Lake Riley, impaired for excess nutrients. This project will identify innovative BMP retrofit opportunities that target soluble phosphorus and promote infiltration and groundwater recharge within this highly-developed area. The downtown Chanhassen BMP retrofit assessment project will be performed in partnership with the City of Chanhassen.
The purpose of this project is to identify effective irrigation and nutrient management best management practices and technologies and the barriers that prevent irrigators, producers, and other agricultural partners from adopting them in Otter Tail County. The primary goal is to reduce nitrate in areas where groundwater is susceptible to contamination as mapped by The Minnesota Department of Health by identifying effective BMPs and addressing the barriers to their adoption.
This is a joint grant application from the Riley-Purgatory-Bluff Creek Watershed District (RPBCWD) and the City of Chanhassen. In 2010, the Minnesota Pollution Control Agency listed Lake Susan as a shallow lake impaired for excess nutrients. A 2013 report recommended a project located at the park pond immediately northwest of Lake Susan as the most cost-effective watershed implementation project. The project calls for an outlet control structure at a higher elevation that will provide increased dead pool storage and the installation of a Minnesota Filter to treat dissolved phosphorus.
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.
