~~ ~ -2- • <br />Flow data for the other streams in or adjacent to the permit area is <br />provided in Table I. <br />Limited water quality data are provided for Ward Creek. The applicant <br />has included one sample for each of two locations, one upstream from the <br />permit area, and the other downstream of the permit area. <br />TABLE I <br />Stream <br />Flow Rate (cfs) <br />Flow Regime Minimum Maximum Average <br />Cottonwood Creek ephemeral 0 12 0.20 <br />Kiser Creek perennial 0.5 50 2 <br />Rowell Draw ephemeral 0 8 0.10 <br />Ward Creek perennial 2 80 8 <br />Williams Creek perennial 0.05 10 1 <br />The surface flows in Ward Creek are acalcium-bicarbonate type water of <br />generally good quality. It has a total dissolved solids concentration of <br />32 mg/1 at the upper sample site, and 396 mg/1 at the lower site. This <br />increase in total dissolved solids may be partially the result of the <br />flood irrigated agricultural activities occuring in between the two sites. <br />(Additional water quality analyses for Ward Creek and some of the ditches <br />in or adjacent to the permit area are provided in Figure 2.04.7(2)(b)-(1) <br />through (6) of the permit application.) <br />As shown on Map 8 of the addendum (Kimball, et al., 1982), numerous <br />irrigation ditches are found in the Ward CreeTc and Williams Creek <br />valleys. Eleven major ditches were identified in the Ward Creek valley, <br />and six major ditches were identified in the Williams Creek valley. In <br />addition, numerous lateral ditches exist to distribute water from the <br />main ditches. The principle source of water for these irrigation systems <br />is Granby Ditch (Granby Ditch and Reservoir Company) which transports <br />irrigation water from reservoirs on Grand Mesa. This water is discharged <br />into Ward and Williams Creeks for subsequent diversion by the various <br />irrigation ditches. Flow data for the major ditches during 1979, 1980, <br />and 1981 is included in Table 11 of the addendum (Kimball, et al., 1982). <br />The applicant has identified four springs in or adjacent to the Red <br />Canyon Mine (shown on Map 2 of the addendum, Kimball, et al., 1982). The <br />source of two of the springs is the Lower Williams Fork Formation and the <br />source of one spring is the alluvial -glacial fill. No source is <br />identified for the four springs. Information about quality and quantity <br />of flow would be obtained from the applicant's proposed hydrologic <br />monitoring plan. <br />
