In the Corn Belt states of the Midwest, intensive agriculture extends up to stream banks, eliminating trees and other riparian vegegation.  In 2013, the USGS Regional Stream Quality Assessment (RSQA) investigated the effects of land use, stream quality, and other stressors on the ecological health of 100 streams i
