that we can foresee to the Narrows Reservoir
from the diversion channel. Some of these
effects would be for instance, the sediment
deposition in the Narrows and our estimates
are that this would probably reduce the con-
servation pool in the Narrows by about 73,000
acre-feet within the one hundred year life.
This would also have probably some adverse
environmental effects, especially on the
recreation, fish and wildlife recreation
benefits. These have not been evaluated in
our analysis.

On the basis of our studies to date, we
have a choice of two courses of action. The
first which we prefer, would be to submit our
interim report this month to the division
engineer recommending the construction of the
West Bijou Creek dam at site "B," but since
the benefits or the justification is based on
the construction of the Narrows, we would also
have to recommend deferral of construction
until the Narrows went into operation.

Also, our recommendations indicate that
we could reconsider the East Bijou and Agate
dams as part of our overall South Platte River
investigation. This is scheduled to be completed
in F.Y. 1976. This re-evaluation would be based
upon a change in the economics that would either
be the interest rate going down or the benefits
going up because of development in the areas,
or something like this. This is one option.
This would also allow the Soil Conservation
Service to take a look at the small impoundments
in the upstream area of the basin, and it should
not interfere with the construction of the
Narrows project.

The other course of action would be to
defer any recommendation on Bijou Creek until
the Soil Conservation Service completes their
studies in the upstream area, and we could come
in in F.Y. 1976 with our recommendations, if
there are any projects justified at that time.
