2. The future use of the gravity-fed water intake system,

3. Location, size and capacity of raw water storage reservoir(s) and supply pipelines,

4. Water treatment plant(s) capacity and location,

5. Pressure zone limits and associated approximate storage tank locations, and

6. Recommended service area limits.

Several events have occurred, or will soon occur, which have prompted preparation of a Master
Plan at this time. Previous master plans for the Town have emphasized the need for Morrison
to construct more raw water storage to meet peak municipal water demands during dry periods
and to accommodate growth. Morrison's decreed augmentation plan requires it to make a
permanent election by the year 2000 whether to store or directly use water from 3'/. shares of the
Warrior Ditch. Morrison has entered in an agreement with Cooley to develop 500 acre-feet of
raw water storage by July 1, 2000. Cooley's gravel pit, located two miles south of Morrison, is
proposed for conversion into a water storage reservoir for use by Morrison, Cooley, and others
needing water. This reservoir is referred in this report as the "Cooley Reservoir." This master
plan assumes the inclusion of the proposed Cooley Reservoir into the Morrison water system,
and builds upon the previous master plan reports prepared by McLaughlin Water Engineers in
May 1983(9), and Wright-McLaughlin Engineers in July 1971(') and November 1978(').

BACKGROUND

In the early 1970's, Morrison's water system represented an overall disastrous situation, being
essentially deficient in all facets, i.e.:

. The Town's water rights would support only limited legal diversions during dry summer

months;

. There was no raw water storage;

. The treatment plant was an old steel pressure filter which, at best, strained the Bear
Creek raw water;
