Article 4. Improvement Of Non-navigable Streams of California Water Code >> Division 5. >> Part 1. >> Chapter 2. >> Article 4.

"Non-navigable streams," as used in this article, means streams and washes in a county which are not declared by law to be navigable and which are not in fact navigable for commercial purposes.

The board of supervisors may provide for widening, deepening, straightening, removing obstructions from, and otherwise improving non-navigable streams the overflow of which interferes with highways, and for protecting the banks and adjacent lands from overflow of non-navigable streams.

The board may make regulations for the use of the streams and the repair and control of the works.

No regulations of the board nor improvements directed by it to be made shall in any manner interfere with the private rights or privileges of riparian owners, miners, or others.

Whenever, in the opinion of the board of supervisors, the general fund is insufficient to defray the cost of the improvements provided for under this article, the board may levy a tax or contract a bonded indebtedness therefor in the manner provided by Title 3 of the Government Code.
