be a dry runoff year (1 year in 10 or greater), the BWCO will initiate a streamflow
monitoring program of the Roaring Fork River at a location within the critical
reach.

Beginning on or about July 15, during these defined dry years, streamflows will
be measured weekly and results reported to the ~ivision Engineer and CWCB.
The measurement will be taken near Basalt just upstream of the Highway 82
bridge crossing.

3. If streamflow measurements within the critical reach drop to 62 cfs (7 cfs above
CWCB minimums), the BWCO will:

A. Coordinate with the ~ivision Engineer to ensure that all junior diversions are
curtailed'.

B. Send letters to all Contractees located in the upper Roaring Fork River
directing them to implement water conservation measures as described in
the BWCO's water conservation handbook. Preparation and distribution of a
Water Conservation Handbook is part of the offered mitigation.

4. If streamflow measurements within the critical reach drop to 58 cfs (3 cfs above
CWCB minimums), the BWCO will issue a directive to all of its contractees in the
upper Roaring Fork basin to curtail all outdoor lawn, garden, and open space
irrigation and aesthetic/piscatorial pond filling.

5. Should a continuous recording streamflow gage be installed in the critical reach,
the BWCO will become a cooperating agency and assist in the annual
maintenance of the gage. The BWCO will contribute up to $2,500 annually for the
effort. With installation of a gage, the BWCO's snow pack monitoring efforts as
described in Mitigation NO.2 above would cease.

I During dry year conditions it is most probable that the entire basin will be under administration after
July 15~ due to the downstream Cameo call. Therefore. it is important that all junior diversions are curtailed.
