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.
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.
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.
Within an 11-county area in southeastern Minnesota, two Nutrient Management Specialists will work directly with producers to reduce nitrogen, phosphorus, and fecal coliform runoff into surface and ground water in the region and the Mississippi River. The specialists will help producers create or revise nutrient management plans, implement Best Management Practices for manure and fertilizer use, and set up on-farm demonstration projects to support farmer-to-farmer learning.
The purpose of this project is to provide a new shared position in southeast Minnesota which will accelerate the adoption of soil health practices by leveraging the existing efforts of the National Resources Conservation Service and other organizations.
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 lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these small communities will receive technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly to the environment, surfacing sewage, or have sewage contaminating groundwater.
