CA Fish & Game Code Section 7181.1

(a)

A person fishing from the shore in the waters of the Colorado River located in Arizona or California shall have in his or her possession a valid sportfishing license issued by the state that has jurisdiction over that shore. That shoreline fishing does not require a Colorado River special use validation as long as the fisherman remains on the shore and does not embark on the water. Any person, however, having in his or her possession a valid Arizona sportfishing license and a California special use validation may fish from the shore in the waters of the Colorado River, or adjacent waters, except canals, drains, and ditches used to transport water used for irrigation or domestic purposes, located in California without a sport fishing license issued by the State of California.

(b)

This section applies only to licenses, permits, reservations, tags, and other entitlements issued through the Automated License Data System.
