Gold Prospecting and Mining Ecology Center

2021-3-22  During the gold rush of the mid-19th century in the Sierra Mountains of California, hydraulic mining mobilized great amounts of waste gravel into the headwaters of the Sacramento River (James 1991). The lower Bear River aggraded as much as 5 m, and is continuing to adjust over 100 years later, which points to the very long time frame of river recovery following human disturbance.

Motorized and gravity siphon aquatic mining may still be allowed in areas that are not salmonid habitat . In salmonid habitat areas, non-motorized mining activities, such as gold panning, are the only form of mining allowed. These activities do not require an individual NPDES permit from Ecology, but will still require a HPA from WDFW.
