thus California has been in substantial compliance with the ISG through 2005. Tracking of use in 2006
is shown below through October I, with forecasted uses at the end of2006 of approximately 3.709
MAF. Although the forecasted uses for 2006 are currently higher than the 2006 target of 3.640 MAF, the
Colorado River Board of California is aware of the issue and adjustments will be made.

Lake PoweD Pipeline: Utah Governor Huntsman signed into law the Lake Powell Pipeline Bill on May
3, 2006. The Bill marks the beginning of project feasibility studies, environmental impact studies, and
the initiation of various permitting processes. Water demands in and around the S1. George area
(Washington County) expected to be 174,000 AF annually by 2039 and perhaps more, which is an
increase of approximately 45,000 AF over current supplies. Studies are expected to run through 20 10 and
the pipeline completed and delivering water by 2020. The pipeline would extend approximately 120
miles and deliver approximately 100,000 AF annually from Lake Powell to the S1. George area. It is
estimated the pipeline would cost $370 million with an option of extending it to the Cedar City for an
additional $120 million.

Bosley Wash Detention Design Update: The CWCB continues to work with Olsson Associates and the
Grand Junction Drainage District to design a detention pond north of 1-70 in Mesa County to alleviate
ongoing flooding problems in the Bosley Wash watershed, between Palisade and Grand Junction.

This watershed experienced extreme flooding in separate events in 1999, leading to the creation of the
"Bosley Wash Drainage Master Plan," prepared by HDR Engineering and sponsored by the CWCB. In
addition to a small demonstration project already implemented, the primary recommendation from the
study included the construction of a large detention facility located north of the Interstate in order to
attenuate flows in the lower watershed.

Design is anticipated to be completed by January 2007, at which point local officials will determine how
to proceed with funding and construction. This project took on additional significance this past summer
when a Utah motorist died while driving through the flooded Interstate on August I, 2006. The design of
