2005 California Fish and Game Code Sections 375 Article 4. California-Arizona Compact

375.  The commission may negotiate the terms of a compact between
the States of Arizona and California with any appropriate officials
of the State of Arizona in relation to reciprocal privileges and
licenses for hunting and fishing by residents of one of the states
within the territorial jurisdiction of the other.  The negotiations
shall include, but shall not be limited to, provisions relating to
sport fishing and the hunting of migratory waterfowl in, on, or along
the Colorado River.
   It is the primary purpose of this section to provide a method
whereby the hunting and fishing opportunities afforded by the
Colorado River may be mutually enjoyed by the residents of the States
of Arizona and California despite the difficulties and
inconveniences that result from the fact that the boundary line
between the States of Arizona and California is the middle of the
channel of the Colorado River.
