5.

Several possibil ities for obtaining storage exist. A new

reservoir could be constructed, or purchase of existing storage

space could possibly be made, such as from Soda Lakes. A logical

possibil ity is the existing Evergreen Reservoir. The Evergreen

Reservoir decree provides for 660 acre-feet for municipal use

including watering of lawns and gardens. Temporary lowering

of the water surface in the Evergreen Reservoir may not be intolerable

once every 15 to 20 years. A more senior storage priority might

be achieved by the transfer of the Evergreen Water System's No.3

priority diversion water right to a storage right. Or by transfer

of Some of the other rights owned by the system.
