8 WATER SUPPLY. RESERVOIR OPERATION and HYDROLOGIC DATA
Reservoir operations at John Martin follow the operating plan adopted
by the Compact Administration on April 24, 1980. This operating plan
was revised on May 10, 1984, and December 11, 1984, but has not
been revised since that time. Accordingly, a system of water storage
accounts exists at JMR into which reservoir inflows are distributed for
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"
whenever referring to the accounts established pursuant to the
operating plan.
General reservoir operations throughout Compact Year 1989 are
described in Table 1, below.
The 1989 Arkansas River Compact Year and the winter season for JMR
began at 0001 hour November 1, 1988 with 78,983.57 acre -feet in
the reservoir distributed as shown in Table 2, below. Winter storage
officially ended at 2400 hours on March 31, 1989 with a total inflow
to the reservoir of 53,504.93 acre -feet. Inflow was distributed to the
agreement accounts pursuant to the operating plan as shown in Table
3, below.
Releases of 3,950.50 acre -feet of agreement account water to various
Colorado District 67 ditches occurred during the period March 15-31,
Other than during this period, no water was physically released from
the reservoir during the winter season. Following the transfer of other
winter water stored at John Martin Reservoir into the appropriate
agreement accounts the allocation of the reservoir contents on March
31, 1989 was as shown in Table 4, below. Total contents according
to the Corps of Engineers was 124,289 acre -feet which agrees closely
with the 124,290 acre -feet reported by the Operations Secretary,for
this date.
With moderate runoff there was no need for flood control operations
during Compact Year 1989, as reflected in Table 5, below.
