The winter deficit is as follows: Jan. 1 - April 30 Nov. 1 - Dec. 31 78.0 AF 39.0 AF Total storage Required Existing Reservoir 117.0 24.5 92.5 New storage Required 2. Additional Water Shares Needed (Annual Basis). If the Gurley system is to be used as the primary water source, acquisition of additional water shares is needed. According to Table IV-J, present average demand with 1330 people is 179 AF; future average demand was estimated to be 405.0 AF per year (in 40 years). Present combined minimum supply are estimated to be 206 AF (60 AF of Gurley Water and 146 AF of flow from other water rights) (Table IV-J). The future annual additional water required was calculated as follows: Water Demand 405.0 AF Existing Gurley Shares (60.0)AF (minimum yield) Water From Other Water Rights (146.0) AF Additional Water Required 199.0 AF The Town is about 200 AF short for future demand (at 40 yr. buildout). The actual shortfall could be considerably more than this if the direct flow rights are less than anticipated. Thus, it appears that either an additional 200 shares are needed from Gurley Reservoir (during a minimum flow year) or other water rights should be acquired. A long range monitoring program for the direct flow water is suggested before committing to additional purchases. It is important to note that the acre feet is based on water needs at 40 years. At present, average demand is about 179 AF; minimum reliable supply is estimated to be 206 AF, resulting in an excess of 27 AF. Thus, acquisition of water can be a phased program. The estimated cost of the 200 Gurley shares at $2500 a share is $500,000, or $12,500 per year. However, IV-2S
