For purposes of this report, we will assume that a low flow year would yield 1 acre foot per share (or 60 AF for the Town's 60 shares). e. Intake ~ Measurement. As discussed in Chapter III the Town's share of Gurley water is taken out at its headgate located above the Town Reservoir. A Parshall Flume is located below the intake, but is warped and not usable. Diversion records from Gurley Ditch are based on meter readings at the water plant. However, this also includes other Town rights. 3. Town Owned Surface Riqhts in Gurlev Canvon. Norwood Water Riqhts. Norwood can also obtain water through its water rights to flows originating in Gurley Canyon. Priority #214 water right (Farmers' Water Dev. Co. Ditch, which originates behind Gurley Dam) states that the Town has the right to collect the first 1/4 cfs from this right. Estimates of the flow from this water right ranges from .10 cfs to .25 cfs (45 gpm to 112 gpm). It must be tapped at the reservoir or be subject to conveyance losses. There is no estimate of flow from Priorities 385 and 425 (the Norwood pipeline). However, it is logical to assume that it would be equivalent to any water flowing down Gurley Canyon in winter that has not been released from the reservoir. Priorities 385 and 425 should also flow in the summer but there is no way to quantify it. The combined direct flow rights of Priorities 214, 385 and 425 is 1.0 cfs; however, the actual physical availability of this water each year is not known because all diversion are intermixed with Gurley Reservoir water and the exact sources in the drainage basin of these water rights is not well defined. An estimate of available water is discussed in Section B3. IV-12
