Final Draft - Preferred Storage Options Plan Southeastern Colorado Water Conservancy District June 8, 2000 The PSOP is designed to meet long-range water management needs on a District-wide, cooperative basis. If the plan is not implemented, chances are good that smaller storage projects, designed to meet the needs of individual entities, could proliferate. The PSOP includes an important element of Fry-Ark Project re-operation. If re-operation is not implemented, an equivalent amount of new storage capacity would need to be developed. The Enterprise, District, and participating entities believe that implementing the PSOP will have fewer environmental effects than implementing a larger number of smaller projects to meet the objectives of individual entities within the District. Storage Options The PSOP was formulated based on evaluations of several potential storage options identified during the storage needs assessment (GEl, 1998). These options include: Storage Potential (at) Re-operation ot the Fry-Ark Project 48.500 Pueblo Reservoir Enlargement 75.000 TUiquoise Lake Enlaigement ........ r-f'\n 1:::l,UUU Lake Meredith Enlargement 75,000 Williams Creek Reservoir Enlargement 36.000 Gravel Lakes 13.000 Re-operation is a non-structural measure that would allow municipal entities having storage allocations in the Fry-Ark Project to store non-Project water in Project storage space. Re- operation (48,500 af) could meet a significant portion of the estimated total storage need of 122, I 00 af. Other non-structural measures such as interruptible supply agreements and water banking were studied during PSGP formulation. The remaining 73,600 af of storage space could be met with a Pueblo Reservoir enlargement or a combination of storage at two or more of the sites listed above. A series of engineering, hydrologic, environmental, and related studies were conducted to evaluate each of the storage options. The hydrologic modeling studies were performed for various combinations of the storage options and were based on meeting the storage objective defined in the storage needs assessment study (173,100 af). Engineering, environmental, and socio-economic studies were undertaken for each of the storage options, with assessments made about the potential impacts associated with various site J \PROJECTS\9906I\ReporulJ>rcferrcd SOP Final wpd III f:I) GEl Consultants.
