ARKANSAS BASIN

Basinwide Conditions Assessment
The SWSI value of -0_8 indicates that for October
the basin water supplies were near normal. Flow at the
gaging station Arkansas River near Portland was 311 cfs, as
compared to the long-term average of 406 cfs_ Storage in
Turquoise, Twin Lakes, Pueblo, and John Martin reservoirs
totaled 61% of normal as of the end of October.
The river call for October stayed relatively senior.
The month began with the call on Fort Lyon Canal"s April 15,
1884 water right and then shifted to Catlin Canal's
December 3. 1884 and Lamar Canal's November 4. 1886
water rights for the latter part of the month.

Outlook
River flows into John Martin Reservoir were
improved over the past few winters for the start of
Conservation storage

Administrative/ManaClement Concerns
An unusual occurrence during October was the
disruption of irrigation due to a significant problem with
tumbleweeds blown into a number of the ditches. The
Highline, Catlin and Oxford Canals all experienced problems
with an unusually high amount of weed accumulation in their
ditches that required enormous expenditure of man-hours to
try to alleviate.
