Midwest streams flow through intensive row cropping

In the Corn Belt states of the Midwestern U.S., intensive row-cropping surrounds small streams, effectively eliminating riparian cover and habitat. Agricultural activities can have profound effects on the chemical and physical characteristics of small streams. In 2013, the USGS Regional Stream Quality Assessment (RSQA)
