Mineral prospecting and placer mining activities in or near water qualify as hydraulic projects and require a permit to protect fish (Chapter 77.55 RCW). The Washington Department of Fish and Wildlife (WDFW) regulates most of these activities through the Gold and Fish pamphlet. Those methods that are not authorized through the pamphlet require an individual Hydraulic Project Approval (HPA).
New suction dredging requirements: individual HPA and annual reporting
Effective November 1, 2019, suction dredging will no longer be approved through the Gold and Fish pamphlet. New rules require that all types of suction dredging may only be conducted after prospectors are issued an individual HPA. Beginning 2021, suction dredgers must submit an annual report to WDFW documenting the previous years’ suction dredging activities by February 1st.
In late summer 2019, we will have further information about how to apply for suction dredging HPAs under the new rules.
Activities not approved through the Gold and Fish pamphlet
As with suction dredging, if you want to work at times or locations, or with equipment, not allowed in the pamphlet you must first get an individual HPA. We will work with you to ensure your proposed activity does not harm fish. You must then follow the provisions in your individual HPA to ensure compliance with the law. Learn more about the HPA application process.
