Figure 9. Mean daily flow (cfs) and shape of the hydrograph for five moderate-
water years (1969, 1973, 1975, 1982, and 1992) compared to 1992, a
low, moderate-water year from 1 May to 31 October in the 2.3-mile
reach of the lower Gunnison River between the Redlands Diversion Dam
and the confluence with the Colorado River. The bottom figure
represents the mean daily flow for 1 May through 31 October for the
2.3-mile reach by 10- and 11-day step increments, e.g., May 1-10,
May 11-20, May 21-31, etc. Solid line in the bottom figure
represents the recommended 300 cfs minimum flow in the 2.3-mile
reach.
