Any call for domestic water outside these dates will stand seepage land evaporation of 5%. The water year ends January ~5th. (A copy of the bylaws is included in the Appen~ix.) According to the ditch rider, flow at the ,Town's headgate on Gurley Ditch is normally adequate until November 1st, probably due to residual :irrigation water stored in stream banks. To assist the Town (in p~evious years), the ditch rider has cracked open t~e valve throughout the winter to release from 1/i8 to 1/4 cfs. Usually the valve was closed by Febr~ary 15th since snowmelt and seeps are adequate to pr~vide water in Gurley Ditch after that. The ditch rider also treats part of the Town's direct runoff water as stored water, since they would be unable to use the full amount during the direct flow period. ;(See Section C2 for further explanation.) Another p~ocedure used in the winter, if icing was occurring w~th the small flows, was to release a higher flow of 140 to 45 cfs for a short period. There is consid~rable lost water with this procedure, though. . According to records from the State Engineer for the years 1951-83, average inflow to the Gurley Reservoir was 23,979 AF. There are presently 7,113 outstanding shares of Fa~mers' Water Development Company. Assuming all w~ter was released to shareholders, the averag~ year yield in this period was 3.4 acre feet per sh~re. However, a representative of Farmer~' Water has stated that average yield per share is 1.2 AF for the 'natural runoff' period, and 1.2 AF for stored water, or a total of only 2.4 AF per :share. The reason for this lower average value is not known. It may represent a different period of re~ord, or may include all storage and ditch losses.i For purposes of this report, an average year ~ield of 2.4 AF/share will be assumed until further iinformation can be obtained; this represents; 144 AF for the Town's 60 shares. In determining the minimum reliable water available for the Town, the low flow years must be evaluated. The three lo~est flow years on record were as follows: IV-ll
