This Amended Feasibility Report supersedes the November 12, 1982

Feasibility Report. Since the November 12, 1982 report was issued,
the following have occurred:

o Broomfield has acquired additional water rights which require
a 12,000 acre-foot reservoir to maximize the yield from City
water rights.

o Cost of land acquisition has been revised to reflect present
estimated costs based on preliminary appraisals and recent
land purchase negotiations.

o Probable maximum precipitation estimates have recently been
updated by the National Weather Service and the United States
Bureau of Reclamation.

o Broomfield growth, water demand, and water revenue estimates
have been revised based on recent statistics and annexations.

o Extensive site geotechnical

The November 12, 1982 Feasibility Report was prepared to specifi-

cally address the issue of inadequate spillway capacity identified in
the Phase I National Dam Safety Report and was therefore 1 imited in
scope. The results of the study indicated that an increase in reser-

voir storage combined with the necessary increase in spillway capacity
was more economically attractive than only increasing spillway capa-
city. Various reservoir sizes were evaluated. A project for enlarge-

ment to 9,000 acre-feet was proposed and 1 ater approved by the CWCB.
