This project will provide an important framework for civic and citizen engagement and communication in the International Rainy River-Lake of the Woods Watershed, which will contribute to long-term public participation in surface water protection and restoration activities.
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.
The goal of this project is to continue best management implementation according to the Redwood River Phase II Implementation Plan (1999) and install phosphorus and total suspended solids (TSS) reducing conservation practices that will help achieve the Lower Minnesota River dissolved oxygen Total Maximum Daily Load (TMDL), and the Minnesota River Turbidity TMDL. The proposed implementation of conservation practices include: water and sediment control basins, grassed waterways, grade stabilizations and streambank stabilizations.
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 Clean Water Fund (CWF) and Outdoor Heritage Fund (OHF) were used together to secure easements on buffer areas. 25 easements have been recorded for a total of 672.1 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 1,152.4 acres. Only the OHF acres are being reported in this final report to be consistent with the approved accomplishment plan.
The Reinvest in Minnesota (RIM) Wetlands Partnership Phase V protected and restored 2,041 acres of previously drained wetlands and adjacent native grasslands on 23 conservation easements. All easements have been recorded. $35,000 of funds from other sources were also used.
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.
