Mr. Douglas Dowling Page 3 Barlow Pit M-74-092 April 5, 2004 North, Range 56 West of the 6th P.M. All 16 shares (4 private rights) are documented on RRLC share certificate no. 1916, reissued on April 21, 2003. Historical use analyses have not been conducted forany of the subject private rights to establish their historical consumptive use, firm (usually dry-year) yield, and return flow patterns. Therefore, as the applicant has been advised previously and as detailed in the conditions of approval herein, such analyses must be submitted with the next plan renewal request. For this plan year only, the consumptive use associated with all of these shares was assumed to be 50%. This was based upon average-year site-specific (as opposed to ditch-wide) analyses performed for other parties' RRLC shares in Division 1 Water Court case nos. 90CW181 and 91CW066. This also means 50% of the delivered water constituted historical return flows, which must be maintained. Return flows from the Brunelli property were lagged back to the stream using Glover techniques and an SDF of 450 days and return flows from the Roth property were lagged back to the stream using an SDF of 120 days. Riverside Reservoir is not currently able to release directly to the South Platte river, therefore, the RRLC water is obtained through the Weldon Valley Ditch by exchange. However, RRLC plans to rework the outlet on Riverside to enable direct discharge to the South Platte River, possibly by 2004. Bythe original 2003 WaterOrder, Dom Ready Mix released 1.5 RRLC private rights. Though the RRLC direct flow rights average a delivery of 16 AF/private right, this wateryeartheyyielded 15 AF/private right. The water commissioner released these, by exchange, over the course of the irrigation season. Pending availability of annual diversion records, the pattern of release was estimated to follow that of Weldon Valley Ditch diversions. Since no recharge credits were available to replace winter depletions, the applicant ordered a bulk release of the remaining 2.5 private rights, yielding 37.5 acre-feet of direct flow reservoir water, in October 2003. The recharge credits can vary greatly from year to year depending upon the amount of water available for diversion at the recharge structures and the amount required by the participating augmentation plans, which have priority overthe RRLC private rights holders. Forthe period of coverage for this plan, unofficial best estimates from Don Chapman, RRLC Superintendent, indicated that the pro rata share of recharge credits allocated for4.0 RRLC private rights total 2.17 acre-feet (final values will be tabulated and reported by RRLC). The monthly deliveries of the recharge credits are shown in the attached table. For the winter months of late 2003 to 2004, no recharge credits were available. hereby approve this substitute water supply plan in accordance with §37-90-137(11), C.R.S., subject to the following conditions: 1. Unless otherwise revoked or modified, this plan shall be valid through May 31, 2004. 2. If this plan will not be made absolute by a water court action by the plan's expiration date, a renewal request must be submitted to this office with the statutoryfee (currently $217) no laterthan April 15, 2004.
