Bear Creek Watershed, a nationally recognized project by the USDA in Story County, Iowa, has 20 years of research under its belt. The research done there involves riparian buffers, and how they benefit the surrounding land and water. Hear from Iowa State researcher Dick Schultz and Iowa Department of Natural Resources researcher Keith Schilling about what they hope to learn from two new projects at the site in part III/III of our Bear Creek series, "Farming for Untroubled Waters." Filmed November 2010.
