. USGS QUAD(s):
BASIS FOR INSTREAM FLOW RECOMMENDATION

Granite.

. The DOW documented that a natural environment is present in the form of a brook and rainbow trout
fishery. __
. Based on the DOW's biological recommendation, flows of3 cfs, summer, and 1.5 cfs, winter, are
necessary to preserve the natural environment to a reasonable degree, However, the winter instream
flow recommendation was reduced to 1.0 cfs (12/1-4/30) based on the water availability analyis. The
DOW believes the lower flow recommendation will still preserve the natural environment.
. CWCB staffhas conducted a water availability analysis and determined these amounts are available for
the Board's appropriation.
. CWCB staffhas 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.
