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…
Our influence on the Turkey River
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
Turkey River and Us
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
The flood that shook the culture of conservation…

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 $202,426.31 invested thru BMP placement
Additional 1097 t/y sediment reduction

Targeted BMP’s have been positioned to ensure longevity and function of lake to be a hub of recreation and educational learning
142 Active CSP contracts, 29 completed since 2005
13 Active EQIP contracts, 42 completed since 1996
Strongest BMP’s include: Terraces, Grade Sta-bilizations, Nutrient Management, Sediment Basins, Contour Buffers, Riparian Buffers
More Conservation…
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)
Urban Conservation
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
NICC Urban Conservation Project: Your
Neighborhood
$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
Ongoing watershed work
Expanding into the watershed…
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
