I I I I I I I I I I I II I I I I I I I Volumes oftransferable water during wet months were estimated for the following conditions: Transferable Water Based on Senior Decreed Water Ri2hts Water rights analyses indicated that decreed water rights senior to the GMWCD were estimated at 355 cfs. Leroux Creek flows exceeded this value in only 9 days in 1948 with a total transferable flow of 1885 acre-feet during 1948. However, this decreed water right was exceeded only in one day during 1949 with a transferable runoff of 18 acre-feet. Therefore, based on senior decreed water rights and daily flows of Leroux Creek, the volume of water available for storage is very small. Transferable Water Based on Senior Decreed Water Ri2hts and Additional Cow Creek Flows As discussed earlier Cow Creek also contributes to the flow of Leroux Creek. This contribution was estimated to be about 8 percent of Leroux Creek flow based on the basin area and difference in elevation of Cow Creek as compared with the basin of Leroux Creek. Therefore, total daily flows at Leroux Creek were increased by 8 percent to account for Cow Creek flows. The 355 cfs decreed water rights were subtracted from the resulting total flow to estimate the amount of daily transferable water. Transferable water was assumed to be zero if total flow was less than the decreed water rights of 355 cfs. In addition, the maximum allowable amount of transferable water was limited to the conditional water right of 260 cfs held by the GMWCD. Table 11 shows the amounts of transferable water estimated based on these assumptions. Table 11 also shows that transferable water was estimated at 2,543 acre-feet and 196 acre-feet during 1948 and 1949, respectively. -20-
