The diversions are further limited to no more than 72,000 acre-feet during the months of April, May and June. This operation was projected to result in an average 'non,project' yield of about 130.000 acre-feet per year. The MVIC also contracted for an allocation of Dolores Project water in an amount necessary to fulfill the ideal irrigation requirement on 26.300 acres of irrigable land under the system. This project water delivery is estimated to range from 0 to 60,000 acre-feet of water. with an average of about 13,900 acre,feet per year. Theoretically. the MVIC would be entitled to a maximum delivery of Project water of 105,500 acre-feet. if it is assumed that the senior rights of the MVIC would have zero yield (26,300 acres x 4.01 acre-feet per acre). In the CROSS WRPM, a 65,000 acre,foot storage account in McPhee Reservoir is assumed to be available to supplement MVIC irrigation demands when the direct flow yield is insufficient, this value being based on the original USSR operation studies for the Project. With this storage account in McPhee. the MVIC no longer needs to operate its own storage in Groundhog and Narraguinnep reservoirs as it did historically to supplement its irrigation demands. In 1991, MVIC and the Dolores Water Conservancy District (District), the sponsoring agency for the Dolores Project, entered into an agreement which provided for an exchange'of up to 2,300 acre,feet of storage from McPhee Reservoir to the upstream Groundhog Reservoir. This exchange water is then released as necessary to protect a continuance of the historic diversions of water rights on the upper Dolores River that are junior to the senior rights of the MVIC. For purposes of the CROSS WRPM. upstream junior water rights that are included in the model are attached to this 'exchange pool' in Groundhog Reservoir to allow diversions that would otherwise be out of priority with respect to the MVIC's senior rights. Narraguinnep Reservoir is an off channel reservoir filled using diversions through the Lone Pine Lateral. Prior to the construction of the Dolores Project, the reservoir was reportedly drawn down extensively in most years to provide supplemental late season irrigation supplies. Since McPhee Reservoir has been on line. irrigation releases from Narraguinnep Reservoir are less than historical, typically in the range of 5.000 to 7.000 acre-feet per year. Releases from the reservoir are recorded by the Division Engineer under WOlD 320700. It should be noted however, that these releases may also include direct flow water from the Lone Pine Lateral that is diverted throuah the reservoir and also that some releases are made from a second outlet directly back into the Lone Pine Lateral. (Personal communication with Les Nunn ' MVIC) The water imported by the MVIC provides the majority of the water used for irrigation in the Montezuma Valley of the Me Elmo Creek basin, either directly or in the form of irrigation return flows. The return flows generally accrue to the drainages of Me Elmo Creek (above Cortez). Hartman Draw. Alkali Canyon, Trail Canyon, Mud Creek, Navajo Wash (near Towaoc) and Yellow 5
