Currently, Pueblo Reservoir and numerous other projects are being utilized as sources of municipal water supply. John Martin Reservoir and Trinidad Lake do not have storage space allocated for municipal water supply. These two projects provide irrigation water supply storage. Several municipalities have complex water collection systems in the Arkansas River Basin which require transmountain diversions, significant storage, or exchanges to operate. Other major communities in the Basin obtain their water directly from nearby well fields. (4) Irrigation. The largest water use in the Arkansas River in Colorado is irrigation. Surface water is the principal source of irrigation water; however, there is some use of ground water for irrigation. Irrigation is practiced along almost all major tributaries. The Corps projects in the Basin John Martin Reservoir and Trinidad Lake provide irrigation water supply. The Division Engineer, Colorado State Engineers Office, is responsible for delivery of the water after leaving Trinidad Lake and John Martin Reservoirs. Tables 5-1 and 5-2 show the decreed water rights below Trinidad Dam and John Martin Reservoir, respectively. (5) Inactive Storage. At Pueblo Reservoir the inactive storage below the conservation pool is a storage zone without allocated usage. Release from this level is possible through the conduits of the dam. The number of conduits and storage volumes are presented in Table 4-4. 4-6
