<br />Table 1. Recommended mean monthly flows for the top of the 15-mile reach in
<br />cubic feet per second. Rate is the percent of years that the recommended
<br />flows should be provided based on winter snowpack levels. For example, in the
<br />wettest 25 percent of years, flows in June should average at least 15,660 cfs;
<br />stated another way, this recommendation should be met in five of every
<br />20 years. During low-water years, June flows should average no less than
<br />6,850 cfs, and such a minimum should occur at a rate of no more than 4 in
<br />20 years (20 percent).
