ARKANSAS BASIN

Basinwide Conditions Assessment
The SWSI value of -3_3 indICates that for March the
basin water supplies were well belO'N normal. The Natural
Resources Conservation Service reports that April 1
snowpack is 60% of normal. Flow at the gaging station
Arkansas River near Portland was 326 cfs, as compared to
the long-term average of 367 cfs. Storage in Turquoise, Twin
Lakes, Pueblo, and John Martin reservoirs totated 51% of
normal as of the end of March_

Outlook
Total reservoir storage during the Pueblo Winter
Waler Program was 81.439 acre-feel, including 29,407 acre-
feet in Pueblo Reservoir, 38.216 acre-feel in off-.channel
reservoirs, and 13.455 acre-feet in John Martin Reservoir
(after distribution to accounts). Total Winter Compact
Storage in John Martin Reservoir was 8,528 acre-feet for the
period from November 1, 2003 through March 31, 2004
Distnbution of Winter Compact Storage into accounts began
at 00:00 hours on April 1, 2004. Snowpack conditions
deteriorated sharply in March in both the Arkansas River
Basin and in west slope basins from which water is imported
to the Arkansas Basin

AdministrativeJManaQement Concerns
A delivery of water to Kansas from John Martin
Reservoir was initiated in lale March during a time of very IQVol
antecedent flows and unfavorable river conditions resulting in
high tranSit tosses.
Major well associations had augmentation plans
approved only on a temporary basis until June 1, 2004 to
attempt to ensure that adequate replacement supplies could
be expected to allow agricultural well pumping
