SUBJECT: Agenda Item 12, July 13, 1984, Board Meeting--
Proposed Mesa-Delta M&I Ground Water Study

.

Background

At its November, 1983, meeting, the Board discussed the
proposed study and took the position that it would consider
financial participation in the study after the Bureau of
Reclamation prepared a plan of study for the Board's review,
That plan of study and study cost estimates .have now been
received.

The Bureau has received authority'to conduct the study under
a "Special Study" approach rather than the usual "Two-Stage"
process, As a special study, the investigation would focus on
evaluating the potential of the basalt aquifer as a source of
supplemental M&I water with less emphasis on development of
alternative plans. However, efforts will be made to identify at
least one ~cceptable plan for development of the aquifer. The
reporting process will be limited to the preparation of one
formal report during the study period, as compared to four
reports under the two-stage process.

According to the proposed schedule, the study would require
four years for completion and is estimated to cost $1,250,000.
It is proposed that approximatelY 50% ($625,000) of the
investigatipn cost be funded by local and state agencies in cash
or with contributed time and effort by project sponsors and
participants.

The study would be performed in accordance with the
"Economic and Environmental Principles and Guidelines for Water
and Related Land Resources Implementation Studies" which became
