I. Central Arizona Project.

The Commission's activities during the year in behalf of the
Central Arizona Project are detailed elsewhere in this report.

II. Interstate Planning and Study.

The Water Resources Planning Act (P.L. 89-80, July 22,
1965) established the Water Resources Council. The President
transferred the functions and committee organization of the
Interagency Committee on Water Resources to the Water Re-
sources Council on April 10, 1966. This transfer included the
Pacific Southwest Interagency Committee. By letter of October
10, 1966, the Water Resources Council requested the Pacific
Southwest Interagency Committee to take leadership and co-
ordinate the comprehensive studies in the Pacific Southwest,
including the Lower Colorado Region. PSIAC accepted this
responsibility' by letter of November 21, 1966. An organization
meeting to begin the Lower Colorado Region study was held
on February 8, 1967. The Department of the Interior was desig-
nated to be lead agency and the Bureau of Reclamation provides
chairmanship of the Lower Colorado Region State-Federal Inter-
agency Group and Staff.

The Commission represents the State of Arizona in the
Comprehensive Framework Study of present and future watel"
supplies and needs in the Lower Basin. A final report is scheduled
for 1970. .

III. Protection of Arizona's interests on tributaries of the
Colorado River and other streams.

In addition to its functions with respect to the main stream
of the Colorado River, the Commission is concerned with pro-
tecting Arizona's interests in other interstate streams such as
the upper Gila River, Zuni River, Little Colorado River, Virgin
River, Kanab and Johnson Creeks and the Santa Cruz River.

With respect to the Virgin River and its tributaries and
Kanab Creek and its tributaries, we shall continue to maintain
the closest relations with Nevada and Utah, to the end of pro-
moting the development and use, of the waters of those streams
and fully protecting Arizona's present and future uses thereof.

As for the Santa Cruz: This presents delicate and diffi-
cult problems which have concerned the Commission and its
l'ngineering and legal staffs for some years. In this connection,
the Commission maintains contact with the International Bound-
ary and Water Commission as well as the areas in Arizona
directly affected. It is possible that a further treaty with Mexico
may be deemed advisable.
