ditches are combined into a single demand node at the Florida Farmers Ditch location. The <br />derived values are consistent with the allocations used by the Conservancy District. <br />Portions of the Florida prof ect water supplies are delivered to lands owned by members of <br />the Southern Ute Indian Tribe. These deliveries are reflected in the total allocation for the <br />Group A ditches (114 acre-feet out of 1,520 acre-feet) and the Group B ditches (1,886 acre- <br />feet out of 24,220 acre-feet). <br />Other than Lemon Reservoir, the only significant storage in the system is provided by Pastorius <br />Reservoir, an off-channel facility which provides regulation of the deliveries under the Florida <br />Canal. It has a decreed capacity of 970 acre-feet. It is not a part of the Florida Project and its <br />operation has not been included in the San Juan Model. <br />Irrigation return flows from the Group A ditches accrue back to the Florida River where they <br />are available for re-diversion by other downstream structures. A portion of the irrigation return <br />flow from the Group B ditches returns to the Florida River upstream of some of the Group A <br />ditches, a portion accrues to the Florida River downstream of the Group A ditches and a <br />portion accrues directly to the Animas River. These return flow locations were determined <br />using the state engineer's database and maps of the irrigated acreage in conjunction with the <br />USGS topographic contour maps. <br />2.7 Pine River Project (Vallecito Reservoir) <br />The Pine River Project was completed by the USBR in the early 1940's and provides a <br />supplemental irrigation water supply to approximately 48,000 acres of land in the Los Pinos <br />River (a.k.a. Pine River) basin in southwestern Colorado and northern New Mexico. These <br />lands include Indian-owned lands on the Southern Ute Reservation and lands outside of the <br />reservation. The principal feature of the project, Vallecito Reservoir, is operated to store <br />surplus flows of the Pine River during the spring snowmelt runoff and subsequently release <br />that water to supplement the late season irrigation demands for a number of downstream direct <br />flow water rights, including a large priority owned by the Southern Ute Indians. The project <br />irrigation water is distributed through a number of privately owned irrigation structures or <br />through structures under the jurisdiction of the Bureau of Indian Affairs. The Pine River <br />Irrigation District manages the project. <br />Vallecito Reservoir (WDID 313518) is located on the mainstem of the Pine River about 18 <br />miles northeast of Durango. The reservoir has a total capacity of 129,700 acre-feet of which <br />125,400 acre-feet is the active pool. The remaining 4,300 acre-feet is dead storage. The <br />reservoir surface area at the normal high water line is about 2,720 acres. Vallecito Reservoir <br />has the following decreed absolute storage right: <br />San Juan & Dolores River Basin Information 2-18 <br />
