8 Communities rest within the watershed, 6 public water supplies, 4 municipal waste systems, Turkey River considered high quality water resource 129,545 acres (11.96% of the total) watershed lay in portions of Winneshiek County: 14 HUC 12 designated watersheds Hummocks, trout, CCOMM, dairy cows, bluffs and kayaks…
Historically this diverse watershed has had strong participation in programs, though few designated watershed projects have been deployed within it The forgotten watershed… “when is it our turn…” Many family farms that have been passed on for generations, very close to the land Our NRCS/District office has 12 individuals working on conservation practices
369 Producers received $1,229,264 to rehabilitate croplands in Winn. Co. Almost 5 years later, some lands are still showing the effects of the floods Enrollment in conservation practices saw steep rise, now there seems to be a wane in some programs
Watershed project started with the inception of the lake 1998 Lake listed on 303(d) List, TMDL completed in 2005; sediments / nutrients 37 acres 33 acres; over ½ of acre feet silted in … with nutrient loading leads to hypertrophic conditions Over 40 years of watershed project BMP’s – 75% cost-share 1590 acres watershed, 73% watershed working lands, 9% urban 12 Landowners of Ag Land, operated by 8 individuals 2.6 of 3.5 miles of feeder streams have protected buffers / filters Since FY2008 $202, invested thru BMP placement Additional 1097 t/y sediment reduction Conservation PracticesAmount Installed Continuous CRP (Filter Strips)64.3 Acres Manure Storage Systems3 Units Terraces35,876 Feet Grade Stabilization Structure6 Units Sediment & Water Control Basins5 Units Grassed Waterways4,606 Feet Stormwater Interceptors(Bio-Swales)3 Units Stormwater Wetlands2 Units

30 acres of hard runoff from Calmar increases runoff problem; literally millions of gallons of water are sent running down streets, 20% of runoff is impermeable surfaces City passed ordinance to exclude grass clippings and other “hurtful” substances from being deposited into the storm sewer system Completed Vision Iowa process that included many urban BMP’s (rain gardens, pervious paving, curb cuttings/runoff boxes, etc…) that would mutually benefit community and watersheds School District has went to no phosphorus lawn fertilizer on their sports complex (14 acres)
Over 423,0000 gals of runoff – 15.6 Acres of impervious surfaces 1.0 ac shelterbelt 2.2 ac short/tall grass native prairie reestablishment Pollinator Garden 3.3 ac Oak Savanna Rain gardens, bio-swales, soil amending, turf grass mitigation The district is making a determined effort to educate the public that urban areas also impact our local waterbodies
$85,098 was secured through a Iowa Fish Habitat Grant to construct a Rock Chute Wetland Strain 788 t/y of sediment and 1024 lbs of phosphorus WIRB grant was applied for to assist Further installation of urban conservation practices and I&E is ongoing
4 watershed have been recognized by the district for additional focus: Bohemian, Brockamp, Wonder and Burr Oak Farmer participation, concerns from water sampling findings, ecological significance, greatest opportunity to have impact within watershed
