which would be subject to regulation by John Martin Reservoir and
releasing the remaining 300 a.f. from Pueblo Reservoir at a rate to
be passed through John Martin and delivered to Lamar's point of
diversion without regulation by John Martin.

This operation was initiated on 6/20/90 and executed until 7/13/90
at which time we were advised that the Ft. Bent ditch, utilized by
the'City of Lamar, washed out in its lower reaches necessitating the
cessation of further releases from John Martin. At this time 621.56
a.f. of Lamar's Fryingpan-Arkansas water remained in storage in John
Martin Reservoir. The operations leading up to this point in time
are summarized in the following tables:

During the ensueing two week period Lamar evaluated its options. It
was deterrrdned that reconstruction of the section of the Ft. Bent
ditch that would have perrrdtted Lamar to resume the operation was
infeasible in the immediate future. There was concern over the
potential loss of the water if left in John Martin Reservoir due to
the terms under which the use of the Reservoir as a regulating
device was granted and the potential ramifications to the Frying
Pan-Arkansas Project should waters native to the Colorado River
Basin be lost to uses outside of the Project boundary. It was
therefore concl uded to take advantage of the river condi tions then
in existence by exchangeing the remaining volume after the deduction
