Figure 17. Maximum daily CPUE (larval fish caught per 100 mJ water sampled) for speckled
dace vs. maximum discharge in cfs (A), number of days discharge was greater than 8,000 cfs
(B), greater than 10.000 cfs (C) and less than 1,000 cfs (0) at Four Corners for 1991-1997
(n = 5 for each analysis, as daily CPUE values were not available for 1991 and 1994).
