Damsite and Reservoir Studies.

Dear Mr. Rea:

This letter confirms our conference of January 8, 1968 relative
to the costs involved in geological feasibility studies for the
Castle Creek and Maroon Creek Reservoirs. The study of both sites
will be considered as one project in the following proposal. 



woman a 

The objectives of engineering geological investigations are,

l} to determine the feasibility of damsites of the locations
'given on Plans 22~7~37 (Castle Creek) and 22w7?38 (Maroon Creek),
2) to recommend alternate sites if necessary, and 3) to estimate
the availability of construction materials. This will be a
feasibility study and will be based on surface investigations only.
In order to fulfill these objectives the following program is
.proposed. . .

.A. Office Studies and Map Preparation

1. Stereoscopic aerial photography at the nominal
- scale 1" 1000? (preferably two sets)a which
are to be provided by you, will be studied in
.the damsite and reservoir areas. Particular .
attention will be given to zones of structural

D. Charges 

I. The fixed charge for the above work, inciuding
travei and-1iving expenses, but not inciudiog
any supplementai subsurface investigations or
work resuitihg in a change in scope or objectives
as stated above, is $3424.00. 5

It is assumed that the owner wii] render a decision in time for
aeriai photography and geologicai field work to be accompiished
in 1968. The charges quoted above are subject to the compiete?

'work'being done in 1968. If the work is postponed until a iater

time, we wijl be pleased to submit revised costs.
