In four of the IS years, 1985 to 1999, minimum flows were below 93 cfs in <br /> <br />August. During September minimum flows were below 93 cfs in 6 years at the Maybell gage <br /> <br />and five years upstream of the Maybell canal. In September the minimum flow at Maybell <br /> <br />averaged 38 cfs less than the combined flow of Craig and William Fork gages. <br /> <br />~ Minimum -o-10-d low flow I <br /> <br />J!? <br />u <br /> <br />500 <br />450 <br />400 <br />350 <br />300 <br />250 <br />200 <br />150 <br />100 <br />50 <br />o <br />1980 <br /> <br /> <br />Median - minimum = 128 <br />Median- 10-dlow=153 <br /> <br />1982 1984 <br /> <br />1986 1988 1990 1992 1994 1996 1998 <br />Year <br /> <br />Figure 3.
