CONCERNING
AN OPERATING PLAN FOR
JOHN MARTIN RESERVOIR

WHEREAS, the Arkansas River Compact Administration,
hereinafter referred to as the Administration, recognizes that, because
of changes in the regime of the Arkansas River, the present operation
of t.he.collS~vation fealuresof JobnMartinoReservoir does not result in
the most efficient utilization possible of the water under its control;
WHEREAS, the Administration finds that adoption of an operating
plan that establishes storage accOlmts for Kansas, for the ditches of
Colorado Water District 67, and for other Colorado ditches as provided
herein may result in more efficient utilization of the water under its
control; and
WHEREAS, the Administration finds that provisions of the
operating plan contained I)erein are permilled by and in compliance
with the Arkansas River Compact, hereinafter referred to as the
Compact; and the Rules and Regulations; and the Bylaws adopted by
the Administration;
NOW THEREFORE, BE IT RESOLVED that the Administration
approves and adopts the following operating plan:
I. Definitions:
A. "Periods of winter storage" consists of the period of time
commencing on November 1 of each year and continuing to the
first exhaustion of conservation storage during the compact
year.
B. "Swnmer storage season" shall be the period of time com-
mencing at the first exhaustion of conservation storage and
continuing to and including the next succeeding October 31.
C. Hlnflows" include all the normal accretions into John Martin
Reservoir, measured or otherwise, including river flow but not
including deliveries into the permanent pool or deliveries of
other water as subsequently defined bereino
D, "Conservation storage" is water stored in the conservation
pool that, but for the adoption of this resolution, would have
comprised of the benefits arising from the construction of John
Martin Reservoir.
E. "Other water" for regulation by John Martin Reservoir is
water delivered. into the accounts established in Section III,
herein, and delivered under the authority of pre-Compact
Colorado water rights. Deliveries of other water are permilled
to gain increased utilization and greater beneficial use.
F. "Compact year" is the water accounting year of the
Administration; it commences on Novem~r 1 of each year and
extends to and includes the next succeeding October 31.
G. Except as provided herein, all words and terms used in this
resolution have the meaning prescribed in Compact Article 111.

winter storage shall accrue. to conservation stor~ge. Con-
servation storage shall be released into the accounts specified in
Subsection 11 D beginning at the first request .for release after
March 31 of account water by a Colorado Water District D1 ditch
or by Kansas or beginning at 8:00 a.m. on April 7, wbichever
occurs first.
Bo Swnmer Storage Season-
(\) When a runoff event occurs during the summer storage
season, such that inflows into John Martin Reservoir are ex-
pected to exceed then existing irrigation requirements of the
ditches in Colorado Water DislrictD1 by at least 1,000 acre-feet,
then the gates on John Martin Reservoir shall be closed com-
mencingcons..rvation.storageexcept for. releases. of.accollnt
water pursuant to Subsection II E, herein.
(2) The ditches in Colorado Water Districtl'i1 will be removed
from the Colorado priority system when the sum of the flows of
the Arkansas River at the Las Animas gaging station and the
Purgatoire River at the Las Animas gaging station, exclusive of
separate deliveries of other water under Section llI, herein,
indicates that conservation storage will occur.
(3) All inflows entering said reservoir during a period of
conservation storage in the summer storage season shall accrue
to conservation storage. Conservation storage shall be released
into the accounts specified in Section 11 D beginning at the first
request for release of account water by a Colorado Water
District h7 ditch or by Kansas or beginning 48 hours after
commencement of conservation storage, whichever occurs
first
C. Exhaustion of Conservation Storage-
(\) For the purposes of Compact Article V F, the con-
servation pool shall be deemed exhausted whenever con-
servation storage has been completely released into the ac-
counts. When this occurs, Colorado shall administer the decreed
rights of water users in Colorado Water District 61 as against
each other and as against all rights now or hereafter decreed to
water users diverting upstream from John Martin Dam on the
basis of relative priorities in the same manner in which their
respective priority rights were administered before John Martin
Reservoir began to operate and as though John Marlin Dam had
not been constructed. However, during these times, inflows
shall, to the extent practical, be measured and released from
the reservoir without temporary storage or averaging flows, and
conservation storage may not be accwnulated nor may storage
in the accounts be increased except by deliveries of other water
under Section lIl, herein.
(2) Administration in Colorado under decreed priorities shall
be initiated so that ditches upstream from John Martin
Reservoir shall deliver to the priorities of Colorado Water
District 67 ditches water at the Arkansas River at the Las
Animas gaging station coincident with the exhaustion of the
conservation storage when taking the flow of all waters, in-
cluding that of the Purgatoire River, into appropriate con-
sideration.
