Water Quality in the Western Lake Michigan Drainages, Wisconsin and Michigan, 1992-95

Major Issues and Findings, Environmental Setting and Land Use Influence Aquatic Life Figures


Benchmark Stream Locations
Twenty benchmark streams in a predominantly agricultural part of the study area were selected for detailed ecological studies (Rheaume, Stewart, and Lenz, 1996). These studies were also done at the eight Indicator Fixed Sites (Sullivan and others, 1995). The ecological studies conducted at the 28 sites were designed to study the effects of environmental setting on aquatic life. The studies conducted at the 20 benchmark stream sites were also designed to define aquatic life conditions in less-degraded watersheds located in primarily agricultural areas.
