2, Arkansas River at Las Animas - In addition to the normal

flows of the Arkansas River at Las Animas, deliveries of

water are made to John Martin Reservoir to be stored in

accounts owned by users located upstream of the reser-

the Arkansas River but are included in the measured flow
at the gage near Las Animas, Such flows must be sub-
tracted from the gaged flows to determine the natural
flow at the gage, This adjusted flow is the amount of
water stored in John Martin Reservoir and eventually re-
leased to downstream users in Colorado and Kansas pur-
suant to the Compact. The practice of delivering other
water into John Martin Reservoir started in 1977, Most
of this other delivered water has resulted from the
operation of the Winter Water Storage Program on the
Arkansas River, in which water is stored in lieu of
direct flow diversions for irrigation 4uring the winter,
As part of this program, water is stored in John Martin
Reservoir for several participants, Storage of program
water occurs during the months of November through March,
