Silver Creek Watershed Project

Silver Creek is located in Howard and Winneshiek Counties in northeast Iowa. The land use in the watershed consists of row crops, grassland, timber and the city of Cresco (pop. 3,868). The land area is 22,410 acres (13,104 acres in Howard County and 9,306 acres in Winneshiek County) and empties into the Upper Iowa River. Silver Creek is on the Iowa Department of Natural Resources' (DNR) 303(d) "Impaired Waters List" due to high bacteria levels. The Howard Soil and Water Conservation District (SWCD) in cooperation with the Winneshiek SWCD has been awarded an Iowa DNR Section 319 project grant to improve the water quality of Silver Creek.

 

Several funding sources with cost-share up to 75% are available for the following practices in the watershed. Contact the Howard SWCD, located at 311 7th St SW #2, Cresco IA 52136, to plan your future project! Neil Shaffer, Project Coordinator, may be contacted at 563-547-3040 x3 or neil.shaffer@ia.nacdnet.net. More information may also be found online at www.howardswcd.org and on Facebook.
