Title 33 › CHAPTER 14 — CALIFORNIA DEBRIS COMMISSION › § 664
The commission must make and approve plans, based on surveys done before March 1, 1893 and any new surveys it needs, to make the rivers easier to navigate. The plans must deepen channels, protect riverbanks, prevent damage from mining debris, erosion, or other causes, and restore navigation as close as possible to its 1860 condition. Hydraulic mining, as the State defines it, may be allowed if it does not harm navigation or nearby land.
