BASIS FOR INSTREAM FLOW RECOMMENDATION

· The DOW documented that a natural environment is present in the form of a brook, rainbow and brown
trout fishery.
· Based on the DOW's biological recommendation, flows of7.25 cfs, summer, and 2.5 cfs, winter, are
necessary to preserve the natural environment to a reasonable degree. However, the winter instream
flow recommendation was reduced to 1.5 cfs (11/15-3/31) based on water availability analysis. The
DOW believes the lower flow recommendation will still preserve the natural environment.
· CWCB staff'has conducted a water availability analysis and determined these amounts are available for
the Board's appropriation.
· CWCB staff' has determined that adequate water supplies exist such that the natural environment may be
preserved without limiting or foreclosing the exercise of valid existing water rights.
