include Louisville Reservoir and Marshall Lake. Louisville Reservoir's capacity
is rated at 171 acre-feet, however, its decree provides for refill which allows
the City to actually store and use 290 acre-feet of water in anyone year under
its storage decree. Louisville Reservoir serves as the City's primary winter
water supply.
The existing Harper Lake is decreed for agricultural use in the amount of
62 acre-feet. Water cannot physically be delivered from Harper Lake into the
treatment plant at the present time. Also, the 62 acre-foot decree for Harper
Lake can't be used for municipal use without a change in type of use, requiring
approval by the Division Water Court.
The City utilizes storage space in Marshall Lake by virtue of its ownership
of shares in the Marshall Lake Division of the Farmers Reservoir and Irrigation
Co. (FRICD) and also by virtue of a contract with FRICD dated November 15, 1978
which allows the City to store junior rights in Marshall Lake whenever extra
storage capacity is available. The City currently owns 103.54 shares of the
total 1,406 shares in the Marshall Lake Division which entitles the City to
7.4% of the amount stored each year in Marshall Lake under its own storage
decrees. The total capacity of ~arshall Lake is 10,258 acre-feet with an
estimated usable capacity of 9,380 acre-feet. Louisville's proportionate interest
in the usable capacity would be approximately 694 acre-feet. A more complete
description of the operation of Marshall Lake is given under Section 11.0,
Storage Requirements.
