The South Clear Creek hydrograph was synthetically derived utilizing the methods
outlined in the USGS Water Resources Investigations Report 85-4086. Based on water
availability, the winter instream flow recommendation was reduced to 0.7 cfs.

SUMMARY

*

*

*

*

The DOW has documented that a natural environment is present in the form of
a .rainbow and brook trout fishery.

The DOW has recommended that a flow of 1.5 cfs in the summer and a flow of
0.7 cfs in the winter are necessary to preserve the natural environment to a
reasonable degree. '

The CWCB staff has conducted a water availability analysis and determined these
amounts are available for the Board's appropriation.

The 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.
