Table 2-1 compares the 1999 land use for both the watershed and the springshed. Large (ca 140 percent) increases in urban land use have occurred during this period at the expense of rangeland and forest. Figure 2-4 illustrates the development of the canal system present within the watershed in 1974. Figure 2-5 depicts the extent of urbanization in1999 overlain on a 1972 aerial photograph. ____________________________________________________________________________________________ Proposed Minimum Flows and Levels for Weeki Wachee River Page 16 of 164 Watershed Characteristics
