Battle Creek Watershed 
Safe, abundant source of drinking water is often taken for granted in this country. As interest in Iowa's water quality grows, the need for preserving valuable drinking water resources becomes more evident. The Battle Creek Watershed Project helps protect and improve these water resources impacted by agricultural non point source pollutants.

FRENCH CREEK DEFENSE PROJECT - SUMMARY
In the fall of 1998 a large "Murphy Farms" confined animal feeding operation went into production on the ridge that drains directly into French Creek, the best wild-trout stream in Iowa. The geology of the area consists of a thin layer of glacial till covering fractured limestone; a direct conduit to the aquifer and the springs that constitute French Creek.
