Cal. Fish and Game Code § 5652

(a) It is unlawful to deposit, permit to pass into, or place where it can pass into the waters of the state, or to abandon, dispose of, or throw away, within 150 feet of the high water mark of the waters of the state, any cans, bottles, garbage, motor vehicle or parts thereof, rubbish, litter, refuse, waste, debris, or the viscera or carcass of any dead mammal, or the carcass of any dead bird. (b) The abandonment of any motor vehicle in any manner that violates this section shall constitute a rebuttable presumption affecting the burden of producing evidence that the last registered owner of record, not having complied with Section 5900 of the Vehicle Code, is responsible for that abandonment and is thereby liable for the cost of removal and disposition of the vehicle. This section prohibits the placement of a vehicle body on privately owned property along a streambank by the property owner or tenant for the purpose of preventing erosion of the streambank. (c) This section does not apply to a refuse disposal site that is authorized by the appropriate local agency having jurisdiction or to the depositing of those materials in a container from which the materials are routinely removed to a legal point of disposal. (d) This section shall be enforced by all law enforcement officers of this state.
