BOARD00907

• Board Meeting Date: 7/13/1998
• Description: ISF Section - New Appropriations - Phase III Report - Notice to Appropriate Instream Flow Water Rights in Water Division 5
• Board Meetings - Doc Type: Memo

instream flow requirements, the CDOW and CRWCD collected biologic and hydraulic data which .
were analyzed by the CDOW and Board staffs. Based on the results of these analyses, the CDOW
prepared a recommendation of the amount of water necessary to preserve the natural environment
to a reasonable degree for this stream (see attached list of Instream Flow Recommendations).

Water Availabilitv Studies

The CWCB staff has conducted an evaluation of water availability for these streams. To determine
the amount of water physically available for the Board's appropriations, the staff analyzed available
USGS gage records, available streamflow models, and/or utilized appropriate standard methods to
develop a hydrograph of mean monthly flows for each recommendation. The staff also relied upon
the flow measurements made as part of the field survey as an indicator of the amount of water
physically available in this stream and analyzed the water rights tabulation for this stream and will
consult with the Division Engineer's Office to identify any potential water availability problems.
Based upon its analysis, the staff concludes that water is available for appropriation on each stream
to preserve the natural environment to a reasonable degree without limiting or foreclosing the
exercise of valid existing rights.

STAFF RECOMMENDATION

For each stream listed in the attached List ofISF Recommendations, the staff recommends that the
Board:

.

. Form its intent to appropriate instream flow water rights for the stream segments identified
on the attached List ofISF Recommendlltions;

. Direct the staff to Officially Notice the Board's intent to appropriate, as outlined in the
Procedures for New Appropriations adopted by the CWCB in 1997.

This action by the Board will start the Public Review and Comment and Board Action Phase (phase
III), as per the Procedures for New Instream Flow Appropriations, as adopted by the Board at its
May 1997 meeting (attached). Final decision by the Board on these recommendations will occur no
earlier than 120 days following the public notice.
