Non-irrigation rights (and multiple-us� .rights which may
include irrigation) adjudicated since 1942 total 71.24 cfs. The
consuml�tive use of those rights may vary widely, depending on the
use. Table 4 shows the estimated flows in the Slate River at full
develo�ment at 15% (10.7 cfs) and 500 (35.6 cfs) depletion. These
should be considered as worst case scenarios since they assume
tull utilization of all water rights.
