Arizona and California. 
Be it enacted hy the Senate and House of Representatives 
of the 
a^ifo°t!ia ^^ 
United States of America in Congress assembled, That the consent of 
Vomp'^ct. 
Congress is given to the interstate compact defining the boundary 
between the States of Arizona and California, ratified by the State of 
Arizona in an act approved by the Governor of such State on April 2, 
1963, and by the State of California in an act approved by the Gov-
ernor of such State on June 11,1963. 
Such compact reads as follows: 
"INTERSTATE COMPACT DEFINING THE BOUNDARY BETWEEN THE STATES 
or 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 mean-
derings 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 Cali-
fornia and the United Mexican States.

ARTICLE II. 
DESCRIPTION. 
"The boundary between the states of Arizona and California on 
the Colorado Rivel* from the point where the oblique boundary between 
California and Nevada intersects the thirty-fifth degree of north lati-
tude, 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 follow-
ing description in general terms of 34 points on the boundary:

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 Sur-
vey will locate the remaining approximately 200 unmonumented sub-
points 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 States of Arizona and California to define the 
boundary; the Coast and Geodetic Survey will then locate the point 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 Com-
missions of Arizona and California have each certified that it is in 
conformity with the General Description of Boundary between Ari-
zona and California set forth herein, it shall be attached hereto and 
marked Exhibit "A" and made a part hereof as though fully incor-
porated herein as the permanent description of the boundary between 
the states of Arizona and California.
