RASIS FOR INSTREAM FLOW RECOMMENDATION

e

· The BLM documented that a natural environment is present in the form of a rainbow and brown trout
fishery.
· Based on the BLM's biological recommendation, flows of 2.5 cfs, summer, and 0.85 cfs, winter., are
necessary to preserve the natural environment to a reasonable degree. However, the summer and winter
instream flow recommendations were reduCed to 1.2 cfs (8/1 - 10/31) and 0.7 cfs (11/1-4/14) based on
water availability analysis. The BLM believes ~e lower flow recommendationwill still preserve the
natural environment.

· CWCB staffhas 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 environmentmay be
preserved without limiting or foreclosing the exercise of valid existing water rights.
