We will characterize environmental drivers contributing to the decline of wild rice using lake sediment cores to reconstruct historical wild rice abundance in relation to lake and watershed stressors.
In 2017 and 2018, Redwood-Cottonwood Rivers Control Area (RCRCA) will collect water chemistry samples from the 10 lakes and 24 stream sites identified in the Redwood and Cottonwood River watersheds. Six samples will be collected at 10 lakes from May through September in 2017; five samples will be collected at 5 lakes in 2018 from May through September. Eleven samples will be collected at each of the 24 stream sites following the Basic Regime in 2017. Sixteen samples at each stream site will be collected in 2017 and 2018 following the E.coli monitoring regime.
The Redwood and Cottonwood River Watersheds have been assessed and many reaches have been impaired for turbidity, bacteria, and low dissolved oxygen. This project will accelerate conservation efforts to reduce overland runoff sediment, bacteria, and nutrient loadings contributing to water quality impairments in targeted subwatersheds.
The Redwood River and Cottonwood River watersheds encompass approximately 2,020 square miles of southwestern Minnesota in the Minnesota River Basin. Land use in these watersheds is mostly agricultural and area geology makes them prone to erosion. Surface water issues within the two watersheds are a concern of local leaders. The counties and Soil and Water Conservation District leaders formed the Redwood Cottonwood Rivers Control Area (RCRCA) Joint Powers Board in 1983 to address sedimentation, water quality and quantity, and erosion issues.
The RIM-WRP program will expand past efforts and provide important benefits to the citizens of Minnesota by restoring and permanently protecting priority wetlands and associated upland native grassland wildlife habitat via perpetual conservation easements. This funding will leverage $12.6 million of federal WRP funds for the State of Minnesota and is expected to create and sustain 343 jobs and income to local landowners, businesses and others in the state based on USDA economic estimates.
Under the CREP partnership with USDA, 38 easements were recorded on a total of 2,732 acres to restore previously drained wetlands and adjacent uplands. One easement is a flowage easement that was required to complete wetland restoration work on an adjacent
The Clean Water Fund (CWF) and Outdoor Heritage Fund (OHF) were used together to secure easements on buffer areas. 84 easements have been recorded for a total of 1,441 acres and are reported in the output tables for the final report (acre total does not include Clean Water Fund acres). The total acreage from both CWF and OHF sources for recorded easements is 2,793.2 acres. Only the OHF acres are being reported in this final report to be consistent with the approved accomplishment plan.
This continuation of the Reinvest in Minnesota (RIM) Reserve buffers program will protect and restore riparian areas, permanently protecting approximately 600 acres on 17 easements. This program will continue utilizing a science-based ranking and selection process and be implemented locally, working with Soil and Water Conservation District (SWCD) staff in targeted areas in the state. Historically, buffer funding was used to expand basic water quality buffers into larger buffers.
This program is a part of a comprehensive clean water strategy to prevent sediment and nutrients from entering our lakes, rivers, and streams; enhance fish and wildlife habitat; protect groundwater and wetlands. Specifically the Riparian Buffer Easement Program targets creating buffers on riparian lands adjacent to public waters, except wetlands. Through the Reinvest in Minnesota Program (RIM) and in partnership with Soil and Water Conservation Districts and private landowners, permanent conservation easements are purchased and buffers established.
We propose identifying hot spots of groundwater chloride pollution of surface waters due to excessive road salt use, which is a long term source increasing chloride impairment of surface waters.
