ARKANSAS BASIN

Basinwide Conditions Assessment
The SWSI value of 0.1 indicates that for June the
basin water supplies were near normal. Flow at the gaging
station Arkansas River near Portland was 1,660 cfs, as
compared to the long-term average of 2,441 cfs. Storage in
Turquoise, Twin Lakes, Pueblo, and John Martin reservoirs
totaled 111 % of normal as of the end of June.
Severe storms in the first part of June produced a
localized impact on the. area extending from John Martin
Reservoir to the Kansas statelineand caused the initiation of
a short duration summer storage event in John Martin
Reservoir, Irrigation demand through June was substantial
as evidenced by the decrease in content of Pueblo
Reservoir (which dropped from 180,832 acre-feet on June 1
to 165,827 acre-feet on June 30) and John Martin Reservoir
(which dropped from 157,894 acre-feet on June 1 to 1.47,534
acre-feet on June 30).

Administrative/Manaaement Concerns
Division 2'{Arkan~as Basin} staff held a meeting with
Water District 67 (Arl<ansas River from John Martin
Reservoir to the stateline) ditch company personnel on June
28, 2001 and discussed the operation of John' Martin
reservoir under the Arkansas River Compact and
subsequent operating plans and resolutions. This meeting
was very helpful to both Division 2 and the ditch company
staff in terms of better communicating operational
information, and identifying areas for improvement. One
important outcome was ~oordination with U.~. Army Corps
of Engineer's staff at John Martin Reservoir to provide
opportunity for weekend sate change-s to be made to better
manage the ditch company's stored waters.

Public Use Impacts
Division 2 river operations staff successfully
coordinated with Pueblo.. County Search and Rescue to
facilitate a 'short-term . reduction in release from Pueblo
Reservoir that enabled the completions of a search and
rescue mission while minimizing impact to water rights down
stream of the rescue effort.
