commonly classified as hydrologic soil group B. The topography of the watershed ranges from 800 to 1,000 ft above sea level with rolling plains having slopes ranging from 0 to 30 percent. This, in combination with the soil groups, provides a wide variety of drainage from poorly to very well drained landscape. Hydrology Hydrology is the study of water and the circulation of water on the surface of the land, in the soil and underlying rocks, and in the atmosphere. Understanding how hydrologic components respond to land use changes and site development is the basis for developing successful watershed and storm water management programs. Traditional development practices tend to cause a sharp increase in the total volume, peak flow rate and frequency of rainwater reaching the rivers and lakes. In addition, channels experience more bankful flood events each year and are exposed to critical erosive velocities for longer intervals. Since impervious cover prevents rainfall from infiltrating into the soil, less flow is available to recharge ground water. Consequently, during extended periods without rainfall, baseflow levels are often reduced in urban streams. Figure 2-8 illustrates the relationship between impervious cover and surface runoff.

Figure 2-9 provides a summary of USGS stream gauging data from 1944 to 2003 for station 04114498 - Looking Glass River at the Tallman Road bridge near Eagle, Michigan (USGS, 2005). The presented information is the monthly mean streamflows in cubic feet per second (cfs). The vertical bar above each month illustrates the range of flow recorded and the horizontal tick mark on each vertical bar is the monthly mean stream flow. Stream flow has varied from a low of 14 cfs in July 1965 to a high of 1131 cfs in April 1947.

These include the SCCUMA Waste Water Treatment Plant (WWTP) in DeWitt Township and four other sites (three in Watertown Township, one in DeWitt Township). These are identified in Figure 2-10.
