Rio Grande and transmountain surface water rights have been acquired by the District to replace these depletions. To replace depletions at the time and place that they occur, up river water storage rights have been obtained through agreements in Rio Grande, Santa Maria and Continental Reservoirs. Through the use of reservoir releases and river diversion rights, the District replaces depletions resulting from wells included in its Augmentation Program. 2.2 Water Availability As previously mentioned, water is made available to the District's Augmentation Program through several augmentation plans approved by the Water Court. The three augmentation plans utilizing water native to the Rio Grande Basin, Case Nos. 03CW4l, 05CW13 and 07CW63 (decree pending) are based upon water measured in acre-feet per year of consumptive use (C.u.). The two augmentation plans utilizing transmountain water delivered through the Pine River Weminuche Ditch are based upon the amount of water diverted and delivered to Rio Grande Basin and are not limited by the historic consumptive use of that water in the Rio Grande Basin. Moreover, diversions through the Ditch, whether for the District's augmentation plans or the irrigation of lands in Water Division No.3, are limited only by priority and water availability at the headgate. Table 2-1 includes a tabulation showing estimated yields of the various decrees and estimated annual total. The tabulation is provided solely for the purpose of this financial analysis and is not and does not purport to be an analysis of the water available to the District, particularly with respect to its transmountain water rights.

Those amounts do not represent the maximum that is available to the Ditch under its decrees or under the District's decrees.
