I I I I I I I I I I I I I I I I I I I A.4.2 A.4.3 Irrigation water requirements for the Gurley Reservoir service area were idealized and tabulated in the Lone Cone Report, referenced earlier. The idealized demands are included from Section 4.2 of this report in Attachment D. Consumptive use requirements for selected crops are shown in Attachment E. Municipal and industrial water requirements are a relatively small but important part of the total water requirements. The maximum rate of flow delegated to meet these requirements is anticipated to be approximately 15 cfs, with typical flows significantly less. Total M and I consumption for the Town of Norwood and Wrights Mesa Rural Water District averaged 56.7 million gallons per year based on data supplied by the FWDC for 1984, 1985 and 1986. Surface Water Supply The Gurley Reservoir system is currently supplied primarily by runoff collected by and diverted through the collection ditch system shown on Figure 2. Runoff from within the natural drainage area for Gurley Canyon provides a lesser portion of the overall water supply. A discussion of available stream gauge records for the area and a tabulation of average annual runoff volumes for drainages feeding the Gurley collection system can be found in Section 4.3 of the Lone Cone Report. This section is included in Attachment D. Groundwater Resources Groundwater is not utilized by Gurley Reservoir as a source of inflow with the exception of relatively minor spring flows which surface within the immediate catchment area. The groundwater resource is therefore not considered in this report.
