	South Fork South Fork is a tributary of the Iowa River in north-central Iowa. It is a 215,000-acre watershed in Iowa’s 'prairie pothole' region. Fifty-four percent of the watershed is productive but poorly-drained, so significant tile drainage provides a direct conduit from fields to surface waters. Eighty-five percent of the land is in a continuous row crop rotation and the watershed is home to a large number of CAFOs, which drives significant corn-corn rotation, and provide abundant manure nutrient resources.

I went to hear about what they had to say and decided to get involved. I’ve learned that a watershed is a complex system that you can't assume anything — everything has to be proven.”
