The Hawk Creek Watershed Project (HCWP) is trying to achieve a reduction in total suspended solids (TSS) and phosphorus, improve the altered hydrology, and increase water storage capacity in the Fort Ridgely Creek subwatershed by implementing suites of projects that include two grade stabilizations with retention ponds, four water and sediment control structures (WASCOBs), and two grass waterways for an estimated pollutant reduction of 280 tons of sediment/yr and 380 pounds of phosphorus/yr.
This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
The goals for this project were to: protect 1,200 acres native prairie/wetland/savanna; restore 250 acres prairie/wetland; enhance 6,000 acres grassland/savanna with fire, invasive species removal, and grazing; and continue a new prairie conservation model. This phase resulted in a total of 1,425 acres protected, 22,298 acres enhanced, and 110 acres restored. When combined with phases 1 and 2 of the Prairie Recovery Program we have cumulatively protected 4,070 acres, enhanced 58,134 acres and restored 314 acres using OHF funds.
This project targets sediment and TSS reduction in the Lake Emily subwatershed. Funded Best Management Practices will address non-point source pollution from agricultural lands, specifically those on steep, erodible slopes and ravines (root cause) that are delivering sediment and phosphorus to the Chippewa River and Lake Emily, an important local resource as it passes through several highly recreated and populated lakes within Pope County along with highly productive agricultural and wildlife lands. These lands have been converted to row crop production.
