component of the South Platte Decision Support System. The objectives of this scope of work
are as follows:

the period 1950 through 2005.
To develop Basin Information memoranda for large basin municipal users that include physical,
legal, and operational information. (Task 5)
To create specific StateMod modeling recommendation sheets based on interviews and Basin
Information Memoranda developed in earlier phases and this phase for basin projects, large
agricultural users, and municipal users. (Task 5)
To develop StateMod modeling recommendations for the inclusion of specific and grouped
augmentation plans, transfers, exchanges, and alternate points of diversions based on
investigations in earlier phases. (Task 7)
To enhance the existing consumptive use model, StateCU, to include new capabilities based on
new technologies, recommendations from State and other users, and recommendations based
on SPDSS Phase 3 efforts. (Task 76)
To coordinate and share the Consumptive Use and Water Budget investigations with water users,
the technical peer review committee members, the State and other SPDSS contractors. (Task

Table 1 lists the Phase 4 activities that have been identified in the SPDSS Feasibility Study
(October 2001 } to achieve these goals. The tasks will be performed by the Consumptive Use and
