o (-"-) ':~.J ~ N ~ SUMMARY (Continued) region. These modified projections are designated as the regionally inter- preted OBERS projections (RI OBERS) and are the basis for the framework plan. This plan is described in detail, then is followed by alternative plans that reflect emphasis on different uses for the available water sup- plies and resources. The alternative p1.ans are identified as: 1. States' alternative to the framework plan (6.55 million acre-foot) level of development, 2. States' alternative at the 8.16 million acre-foot level of development, and 3. States' 'alternative for water supply physically available at site in the region (9.44 million acre-feet), Comparisons of the framework plan and alternate levels of development are shown in the table on the following page. Program costs borne by the Federal Government for the framework plan would total about $3 billion for the 55 years for installation; annual OM&R (operation, maintenance, and replacement) costs would increase to about $48 million by 2020. Non-Federal entity costs would total $10 bil- lion for installation by 2020, with OM&R costs increasing to over $646 million annually, particularly for thermal-electric power and recreation.

At the two higher levels, augmentation will be required. Land and mineral resources exist in sufficient quantity to meet all projected levels of development. With minor exceptions, hunting and fish- ing needs will be met. ii
