8. WATER SUPPLY. RESERVOIR OPERATION. and HYDROLOGIC DATA f John Martin Reservoir (" JMR") is operated pursuant to the "Resolution Concerning an Operating Plan for John Martin Reservoir" ("Operating Plan" or "Operation Plan") adopted by the Compact Administration on April 24, 1980. Minor revisions to the Operating Plan were made on May 10, 1984 and December 11, 1984, but the plan has remained unchanged since 1 984. Accordingly, a system of water storage accounts exists at JMR into which reservoir inflows are distributed for physical release at a later date. While these accounts have often been referred to as "Article II" and "Article III" accounts, the correct designation, based on the organization of the Operating Plan Resolution, is "Section II" and "Section III" accounts. This report uses the term "Section" or "agreement" whenever referring to the various accounts established pursuant to the Operating Plan. More specifically, the Operating Plan created the following account system at JMR: . Accounts established by Section 11 .. Kansas account . Colorado Irrigation District 67 ditch accounts (Fort 8ent Canal, Keesee Canal, Amity Canal, Lamar Canal, Hyde Canal, Manvel Ditch, X,Y/Graham Ditch, Buffalo Canal, Sisson-Stubbs Ditch) .. Kansas transit loss account . Accounts established by Section 111 . 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 1991 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, 1990 and October 31, 1991- During the year 65,020.79 acre-feet of water was stored in JMR, 12,654 acre-feet evaporated, and 61,569.03 acre-feet was released to downstream users, This operation resulted in a reduction in contents for the year of slightly over 9,200 acre-feet. The remainder of this section provides a detailed description of reservoir operations. 11 ARC.""
