IV. PRELIMINARY COST ESTIMATE
We have made, we believe, a reasonably conservative estimate of the
cost of the work necessary to enlarge the reservoir sufficiently to provide
6,400 acre feet of additional storage. Drawings No. 1 and No. 2 show prelimi-
nary designs for the major features needing modification. The tabulation
below indicates the estimate of cost for each feature, and the total estimated
cost of the enlargement.
