Figure 5-2 R-B Index at Eagle (USGS 04114498) 0.2 0.15 R-B Index 0.1 0.05 0 1944 1954 1964 1974 1984 1994 2004 An illustration of the watershed depicting the estimated percent imperviousness is provided in Figure 5-3. Tabulated in Table 5-4 is a summary of the percent imperviousness by subwatershed. For the purposes of these computations open water such as rivers, lakes and streams were assumed to have zero impervious area. As indicated in the Relevance of Impervious Cover section (Section 3), watersheds with an impervious cover less than 10 percent are considered sensitive, watersheds between 10 and 25 percent are considered impacted, between 25 and 60 percent the watershed is considered non-supporting and greater than 60 percent the watershed is effectively just urban-drainage (Schueler, 1994). A watershed wide average percent impervious for the Looking Glass River watershed was computed to be 9.2 percent which places the watershed in the sensitive category. However when considering smaller units within the watershed impacted, non-supporting and urban drainage categories are identified. Table 5-4 also shows the percentage of area within each subwatershed in each of the four categories. Refer to Figure 2-1 for reference to the subwatershed locations. 5-12 Looking Glass River Watershed April 2007
