The management and regulatory authority for areas around Lake Quinault above the Ordinary High Water Mark (OHWM) is shared between the National Park Service, the U.S. Forest Service, Grays Harbor County, and the Quinault Indian Nation. The Quinault Indian Nation owns and manages the waters and bed of Lake Quinault up to the OHWM.
The plan will assess the impacts of uses and activities above and below the OHWM and will include recommended strategies to protect the lake from damaging activities above and below the OHWM.
