3.4 Flow in the RICD Reach <br />Based on the synthetic long term Emma gage record adjusted for irrigation depletions, flow - exceedence <br />curves for the RICD reach were developed. The results, on a bi- monthly basis, are summarized in Table <br />3. The bi- monthly flow — exceedence curves are included as Appendix C. A statistical distribution was <br />not required as the quantity of data points for each bi- monthly period is sufficient to allow a reliable <br />normal distribution. The record at the Glenwood Springs gage used to develop the flow — exceedence <br />curves spans 98 years from January 1907 through December 2004. As such, each bi- monthly period <br />includes approximately 1,500 individual data points, sufficient to develop accurate, normally distributed <br />flow - exceedence curves. <br />3.5 RICD Reach Flow Compared to RICD Claims <br />Table 4 summarizes the percentage of days over the 98 year study period that the claimed flow is <br />available in the RICD reach. With the exception of January 15 — March 15 and December 16 — 31, the <br />claimed flow is exceeded more than 70% of all days. The claimed flows are graphically depicted on the <br />flow — exceedence curves in Appendix C. <br />3.5.1 Volume of Flow in the Reach Commanded by the Claimed Flow <br />Table 5 summarizes the volume of water commanded by the RICD claim compared to the historical <br />average flow volume. The table includes analyses for both the 12 hour per day claim requested in <br />06CW77 (8:00 AM — 8:00 PM) and a 24 hour per day call. <br />The average annual volume through the RICD reach is 492,268 acre -feet distributed as shown in the <br />upper section of Table 5. The annual amount claimed by the RICD as applied for in 06CW77 is 174,497 <br />acre -feet or 35% of the available flow. If the call is assumed for a 24 hour period, the volume <br />commanded by the RICD doubles to 348,995 acre -feet or 71 % of the available flow. <br />3.6 Ruedi Reservoir Storage / Release impact on RICD Reach Flows <br />Ruedi Dam and Reservoir are located on the Fryingpan River, a tributary of the Roaring Fork River, on <br />Colorado's West Slope about 13 miles east of Basalt, Colorado. Ruedi Reservoir has a total capacity of <br />102,373 acre -feet at a water surface elevation of 7766.0 feet. The reservoir is operated on an annual <br />cycle. Steady winter releases draft the reservoir such that it is filled with the spring snowmelt runoff, while <br />releases to the Fryingpan River are maintained below the safe channel capacity. The reservoir provides <br />12 <br />
