8. WATER SUPPLY and RESERVOIR OPERATION I. John Martin Reservoir ("JMR") is operated pursuant to the "Resolution Concerning an Operating Plan for John Martin Reservoi~' ("Operating Plan" or "Operation Plan") adopted by the Compact Administration on April 24. 1980 and most recently revised on December 11, 1984. The Operating Plan establishes a system of water storage accounts at JMR into which reservoir inflows are distributed for physical release at a later date. These accounts are referred to as "Section II" and "Section III" accounts based on the section of the Operating Plan under which they were created. More specifically, the Operating Plan created the following account system at JMR. Accounts established pursuant to Section II: Kansas account, Colorado Irrigation District 67 ditch accounts (Fort Bent Canal, Keesee Canal. Amity Canal, Lamar Canal. Hyde Canal. Manvel Ditch, X-Y/Graham Ditch, Buffalo Canal, Sisson-Stubbs Ditch), and Kansas transit loss account. Accounts established pursuant to Section III: Amity Great Plains Reservoir account, Fort Lyon Canal account. Las Animas Consolidated Ditch account. In addition to these accounts. water is also accounted for at JMR as conservation storage and in the permanent and the flood control pools. An overview of general reservoir operations during Compact Year 1993 is summarized in Table 1. This table reflects actual reservoir operations showing the volumes of water physically stored. released, and evaporated at JMR between November 1, 1992 and October 31. 1993. During the year 129,863.33 acre-feet of water was stored in JMR, 17,895 acre-feet evaporated. and 83,978.20 acre-feet was released to downstream users.
