Gold A history of gold uses, mining and prospecting over thousands of years. Videos: Panning Gold How to Pan for Gold Learn about panning by watching four experienced panners.
Motorized mining activities can cause habitat disruption, creating suspended sediment in the river and smothering salmon spawning gravel and incubating salmon eggs. This can lead to fewer juvenile salmon surviving, decreases the amount of adult fish available for harvest, and impacts food sources for other animals such as orcas.

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. *Potential use areas are areas outside of salmonid habitat and where Ecology may issue individual NPDES permits pending application review. Read our Frequently Asked Questionsfor more information.
As of June 11, 2020 you will need both a HPA and a NPDES permit to legally conduct motorized or gravity siphon aquatic mining activities.
and prospecting if you use a gold pan, mini rocker box, or non motorized, small sluice box. You must have a formal HPA for sluicing and dredging. The DFW publishes the booklet Gold and Fish to provide details and definitions for use by recreational gold panners. Be sure to obtain and read a copy ofGoldandFish, which you must
Hydrogeochemical prospecting for gold: Groundwater collected from wells, springs, and drill holes may provide clues to the presence of subsurface gold deposits. As groundwater flows through the deposit, minute amounts of gold are leached from the rocks.

The Washington State Gold Rush began in 1873, when gold was discovered at Swauk Creek. This discovery came after more than a decade of unsuccessful mining in the region. Gold was discovered in every Washington county at the height of the Gold Rush. Panning continues throughout Washington State today and some places in the state produce good ...
