15. Availabilitv of the Acauired Water for Subseauent Use Downstream

Acquisition of the Hat Creek Ditch water right will leave up to 21 acre-feet of water in stream that
was previously lost to the system through consumptive uses. That water could be available for
subsequent use on Brush Creek and the Eagle River, as long as existing instream flow water
rights are not injured.

16. Costs to complete the transaction. or other associated costs

There are various costs associated with completing this water right acquisition. Helton &
Williamsen, P.C. prepared an engineering report evaluating the Hat Creek Ditch water right's
historical uses. Potential costs to the Board include costs associated with analysis of the water
right acquisition proposal, including updating or expanding the Helton & Williamsen report, and
any costs associated with preparing, filing and prosecuting a change of water right application
for the instream flow use. Since the Board already holds and protects existing instream flow
water rights on Hat Creek and East Brush Creek, staff does not expect to incur significant
additional costs to protect the acquired rights.

Staff Recommendation

Pursuant to ISF Rule 6b, the Board's consideration of this proposal at this meeting will initiate
the 120-day period for Board review. No formal action is required at this time. Staff believes
that this proposed acquisition will benefit the ISF Program. The initial presentation of this
proposal provides an opportunity to the Board and the public to identify questions or concerns
that staff or the CWT will address at this or a subsequent meeting.
