2005 California Government Code Sections 175-176 Article 3.5. Colorado River Boundary Compact

175.  The interstate compact executed between the States of Arizona
and California, as set forth in Section 176 of this chapter, fixing
the location of the boundary line between the two states from the
southern boundary of the State of Nevada to the point on the
international boundary which is common to the boundaries of Arizona
and California, and the United Mexican States, is hereby ratified and
approved.
176.  The provisions of the interstate compact between the States of
Arizona and California referred to in Section 175 are as follows:
      INTERSTATE COMPACT DEFINING THE BOUNDARY BETWEEN THE STATES OF
ARIZONA AND CALIFORNIA
Article I.  Purpose.
   The boundary between the States of Arizona and California on the
Colorado River has become indefinite and uncertain because of
meanderings in the main channel of the Colorado River with the result
that a state of confusion exists as to the true and correct location
of the boundary, and the enforcement and administration of the laws
of the two states and of the United States have been rendered
difficult.
   The purpose of this compact is to fix by reference to stations of
longitude and latitude the location of the boundary line between
Arizona and California on the Colorado River from the southern
boundary of the State of Nevada to the point on the international
boundary which is common to the boundaries of Arizona and California
and the United Mexican States.
      Article II.  Description.
   The boundary between the States of Arizona and California on the
Colorado River from the point where the oblique boundary between
California and Nevada intersects the thirty-fifth degree of north
latitude, said point being common to the boundaries of the States of
Arizona, California and Nevada, to the point on the international
boundary which is common to the boundaries of Arizona, California and
the United Mexican States, shall be in accordance with the following
description in general terms of 34 points on the boundary:
      General Description of Boundary Between Arizona and California
   Point No. 1.  The intersection of the boundary line common to
California and Nevada and the centerline of the channel of the
Colorado River as constructed by the U.S. Bureau of Reclamation, said
point being common to the boundaries of Arizona, California, and
Nevada, where the 35th degree of north latitude intersects the
centerline of said channel; thence downstream along and with the
centerline of said channel to the southerly end of said construction
to
   Point No. 2, which is located in the center of the channel of the
Colorado River approximately one-half mile northerly from the
A.T.&S.F. Railway Bridge at Topock; thence downstream on a straight
line to
   Point No. 3, which lies in the Colorado River vertically below the
centerline of the A.T.&S.F. Railway tracks at a point midway
face-to-face of abutments of the A.T.&S.F. Railway Bridge at Topock,
Arizona; thence on a straight line downstream to

approximately 8,400 feet northward of the center of the overflow
section of Imperial Dam; thence on a straight line to
   Point No. 16, which is the center of the overflow section of
Imperial Dam; thence on a straight line normal to the longitudinal
axis of Imperial Dam to
   Point No. 17, which lies at the intersection of the last described
line with a line extending northeasterly from the center of the
overflow section of Laguna Dam and normal to the longitudinal axis of
the said Laguna Dam; thence southeasterly on a straight line to
   Point No. 18, which is at the center of the overflow section of
Laguna Dam; thence on a straight line to

thence departing from the river on a westerly course along the
extension of the above-mentioned section line about 0.65 mile to
   Point No. 21, which will be the northwest corner of the northeast
quarter of Section 8, Township 8 South, Range 22 West, Gila and Salt
River Meridian, which shall be resurveyed in establishing this
boundary; thence southerly along the centerline of said Section 8
about one-half mile to

south of the northeast corner of said Section 35, thence southerly
along the east line of said Section 35 to
   Point No. 32, which lies at the center of the Colorado River,
i.e., midway between the north and south shore lines just downstream
from the centerline of the old U.S. Highway 80 Bridge across the
Colorado River; thence down the center line of the Colorado River
midway between the shore lines on the right and left banks to
   Point No. 33, which is a point in the Colorado River vertically
below the center of the new U.S. Highway 80 Bridge; thence down the
centerline of the Colorado River midway between the shore lines on
the right and left banks to
   Point No. 34, which is the intersection of the centerline of the
Colorado River and the International Boundary Line between California
and the United Mexican States, which point is common to the
boundaries of Arizona, the United Mexican States, and California.
   These points will be marked on existing bridges and dams and where
appropriate will be monumented.  Between each of these points will
be a number of subpoints not monumented.  The total number of points
and subpoints will approximate 234.  The United States Coast and
Geodetic Survey will locate the above-mentioned 34 points on the
boundary by precise geodetic surveys.  The Coast and Geodetic Survey
will locate the remaining approximately 200 unmonumented subpoints by
precise photogrammetric methods and will provide a list of the
geographic positions and state coordinate positions (transverse
Mercator system for Arizona and Lambert system for California) of
each of the 234 points on the boundary.  The approximately 200
unmonumented subpoints will be identified on copies of the aerial
photographs by the State of Arizona and California to define the
boundary; the Coast and Geodetic Survey will then locate the points
so identified by analytic aerotriangulation (photogrammetric
methods).
   When the survey and boundary description has been completed by the
United States Coast and Geodetic Survey and the Boundary Commissions
of Arizona and California have each certified that it is in
conformity with the General Description of Boundary between Arizona
and California set forth herein, it shall be attached hereto and
marked Exhibit "A" and made a part hereof as though fully
incorporated herein as the permanent description of the boundary
between the states of Arizona and California.
      Article III.  Ratification and Effective Date.
   This compact shall become operative when it has been ratified and
approved by the legislatures of the states of Arizona and California,
and approved by the Congress of the United States.
   Executed in duplicate this 12th day of March, A.D., One Thousand
Nine Hundred and Sixty-three, at Sacramento, California.
