Photographs showing land types that are representative of those found in the Onondaga Lake basin, New York, including a steep boulder-covered channel in a forested basin (2007), a low-gradient channel in a wetland area (2005), an agricultural area overlooking Otisco Lake (2008), and commercial and transportation land uses in an urban setting (2008). All photos were taken by William F. Coon. Water-Quality Characterization of Surface Water in the Onondaga Lake Basin, Onondaga County, New York, 2005–08 By William F. Coon, Brett A.
