Re: Agenda Item No. 20, November 13-15,2006 Board Meeting: S.G. Company (Case No.
5-04CW238) -- Injury with Mitigation Proposal

This agenda item addresses a proposed pretrial resolution under ISF Rule 8i. (3) (Injury Accepted
with Mitigation). Rule 8i.(3) requires the Board to consider an injury with mitigation proposal using
a two meeting process. This is the second meeting of the process. At its July 2006 meeting, the
Board made the preliminary determination that the natural environment of the Blue River could be
preserved to a reasonable degree with the proposed injury to the Board's Blue River instream flow
water right if S.G. Company provides the proposed mitigation.

Backeround
S.G. Company's application seeks conditional surface and storage rights, changes of water rights,
and a plan for augmentation including exchange. The application is in connection with S.G.
Company's Oxbow /Floodplain Fish Habitat Improvements ("Improvements") located on the Mt.
Powell Ranch on a 3.5 mile reach of the Blue River north of Silverthorne in Summit County,
Colorado. The Improvements include the Oxbow fishery channel and a restored historic floodplain
channel, together with associated open channels, fill ditches and return facilities to the Blue River.
The Board filed a statement of opposition to this application because the exercise of the proposed
rights could adversely impact the Board's instream flow ("ISF") water rights listed below.
