1. Facilities for diverting up to 30 cfs of raw water from the North Fork of
Kannah Creek to Juniata Reservoir.

2. Enlargement of Reeder Reservoir, establishing relative costs for various
storage volumes up to approximately 700 acre-feet.

3. Prov i ding an interconnect i on permit t i ng Reeder Reservo i r to discharge to
the proposed new Kannah Creek Flow Line. This component, in conjunction
with number 2 above would allow additional storage of raw water for
municipal use.

2.3 EXISTING CONDITIONS

The existing capacities of the various principal components of the City water
supply system as defined by the City Water Department are summarized in Table
2-2. Contrasted with these in Table 2-3 are the annual water demands according
to City records for the twelve year period from 1973 - 1984. An evaluation of
the adequacy of these system capacities is not within the scope of this report.
However, to provide some means of determining the relevancy of the data, it can
be said that the raw water flow line and the water treatment plant should be
capable of delivering the maximum day demand, which is typically estimated at
approximately 3.0 times the average day demand for cities comparable to Grand
Junction. Thus, for 1984 (maximum day demand=15.6 MGD) it is apparent that
treatment capacity was adequate while flow line capacity was exceeded,
necessitating a draw on plant raw water storage. In the drought year of 1976,
however, the maximum day demand was in excess of 20 MGD, thus depleting
finished water storage as well as plant raw water storage. In fact, the
average maximum day demand for the twelve year period, 18 MGD, is indicative of
