<br />than adequate to meet the fishery requirement. A minimum flow of 1.3 cfs would be <br />adequate during winter. <br /> <br />Instream Proposal. Table 1 is a summary of Wheeler's instream flow proposal. <br />For the stream reach upstream of East Tennessee Creek, I conclude that there is <br />adequate streamflow in Tennessee Creek to support an in stream flow appropriation of <br />19 cfs during May 15 through mid summer, with less than two cfs available for the <br />remainder of the irrigation season of most years. Thereafter, I recommend a 4.4 cfs <br />in stream flow appropriation through November 30, based on the comparison with <br />Halfmoon Creek. I recommend a 2.3 cfs instream flow appropriation during December 1 <br />through May 14, based on the drainage area calculations. <br /> <br />My recommendation for the instream flow appropriation upstream of East <br />Tennessee Creek is consistent with the existing instream flow appropriation for Longs <br />Gulch (2 cfs) and upper Tennessee Creek (5 cfsl. As shown in Table 1, the annual <br />average instream flow appropriation for the proposed segment is equal to 7.1 cfs, <br />which generally matches the 7-cfs combined appropriation for Longs Gulch and upper <br />Tennessee Creek. <br /> <br />Streamflow Availabilitv. Table 2 is a summary of the estimated number of days <br />when the Tennessee Creek instream flow would not be satisfied by natural flows. <br />These periods were estimated on the basis of the long-term gage of the Arkansas River <br />near Leadville. I estimate that the instream flow would not be satisfied for an average of <br />60 days per year. During a critical drought year such as 1977, the in stream flow would <br />not be satisfied for approximately 249 days. These figures indicate, in my opinion, that <br />there would be a reasonable balance between water availability and the instream flow <br />water right. <br /> <br />Table 3 is a summary of the estimated number of days when the Tennessee <br />Creek instream flow would not be satisfied if the CWCB staff recommendations are <br />adopted for season flows of 19 cfs, 9 cfs, and 7 cfs, with no segmentation at East <br />Tennessee Creek. As shown in Table 3, the instream flow would not be satisfied for an <br /> <br />6 <br />
