Just buy a fishing license, and youll get a vehicle access pass. Watch out though, vehicle access pass only works at some spots. Other spots you need a discovery pass, which is stupid and a way for the state to make more money.
Public boat launch is free but you need your fish and wildlife window card or a discovery pass for parking.
There's technically no cost up front but you need either a launch pass or Discovery pass
I would suggest visiting wdfw.wa.gov for more information about any licencing or fees associated with the use of the lake. I go only to take pictures so I am unsure what may be needed! I hope the website helps!😊
