LoeuPreeipitation I <br /> <br />Figure 6 <br /> <br />The estimated local inflows for 1991 through 1994 are generally consistent in the August <br />through October period with values that range from 150 cfs to 450 cfs even though river <br />inflows were much greater in 1993. A significant difference between the local inflows <br />experienced in 1991 and 1993 versus 1992 occurs during November. In 1991, 1993 and <br />1994 a significant drop in local return flows was calculated around mid November, but <br />not in 1992. It's our general belief the drops are the result of other events that result in <br />low or zero calculations of local inflow, and that local inflows are relatively consistent. <br />After the irrigation season the 1991, updated 1993, and provisional 1994 data indicate <br />that local inflows in December may be on the order of 100 cfs. The following is a <br />summary of what we attribute to cause the major drops in calculated local inflow. <br />
