General Background
Pursuant to Rule 5h. of the Instream Flow and Natural Lake Level Rules ("ISF Rules"),
the attached stream segment is being recommended to the Board for Final Action.
This stream segment has been noticed pursuant to the ISF Rules and the public was
afforded an opportunity to comment pursuant to Rule 5g. at the July 2007, CWCB
meeting. This stream segment is located in Water Division 6 in Moffat County and listed on the
attached instream flow tabulations.

Technical Investigations
The Board was provided detailed information regarding all field data, studies and
analyses for the stream segment at the July 11-12, 2007 Board meeting. At that
meeting the Board declared its intent to appropriate the specific instream flow water
rights.

Natural Environment Studies
The USDI Bureau of Land Management (BLM) has conducted field surveys on these streams
and found a natural environment which can be preserved. To quantify the resources and to
evaluate instream flow requirements, BLM staff collected biologic and hydraulic data, and the
CWCB staff reviewed and analyzed these data. Based on the results of these reviews/analyses,
the CWCB staff prepared recommendations for the amount of water necessary to preserve the
natural environment to a reasonable degree for the stream displayed on the attached tabulation of
instream flow recommendations.

Water A vailabilitv Studies
The CWCB Staff has conducted an evaluation of water availability for this stream. To
determine the amount of water physically available for the Board's appropriations, staff
