Over the 1986 through 1989 <br /> �. period, while the drou ht had be� P � g gun, water supplies remained near normal. It wasn't until ' <br /> after 1989 that significant reduction in water supply occurred. There was a decline in the <br /> groundwater table during the 1990 to 1993 period; however, in 1993 there was recovery <br /> due to the wet 1993 year. Generally, in the project area the groundwater levels increased <br /> by about 20 feet over the 1986 to 1989 period. Over the 1989 to 1993 period, the levels I <br /> dropped to near the 1986 levels. In 1993, levels rebounded on the order of 20 to 25 feet. i <br /> Individual well hydrographs are presented in Figure 3 for the project area. The <br /> ' well locations are,shown on Figure 1. These hydrographs demonstrate the sustainability I <br /> of the groundwater through the 1987-1992 drought period. Such sustainability <br /> demonstrates a long-term average surplus of supply as compared to existing demand. j <br /> STODDARD&ASSOCIATES Assessment of Water Supply Impacts AUGUST 1995 �PAGE 4 } <br />
