Bevens and Carver Creeks Exclusion and Streambank Restoration Grant
Projects and Practices 2014
Exclusion activities for landowners will reduce the amount of uncontrolled access points for livestock to enter the stream. This project will install fencing for ten individual properties, resulting in an estimated reduction of 13 percent of available fecal coliform bacteria
by excluding approximately 100-150 head of livestock.
Concurrent with the exclusion fencing projects, stream bank restoration will reverse the negative impacts of livestock grazing and trampling areas next to the water's edge. These activities will include bank stabilization, replanting of native vegetation and establishing native buffers. These activities are estimated to reduce the amount of sediment reaching the stream by 50 tons.
LOCAL LEVERAGED FUNDS
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. With a total of roughly 75 miles of stream length between Bevens, Silver and Carver Creeks, it is reasonable to expect that at least fifteen sites will have evidence of livestock access.
This project will construct exclusion fencing for livestock to remove uncontrolled access to the streams. Included in constructing exclusion fencing will be the restoration of stream banks that have been damaged due to excessive grazing and trampling. The reduction in erosion from these targeted areas will also help reduce turbidity, which is a goal set forth in the Bevens and Carver Creek Turbidity Total Maximum Daily Load study that was approved last year.
