I remember that I wondered about if I could hunt a lake last year. I called everyone. Googled a lot, and called some more. Between Fish and Wildlife, and the Sheriff. It was open

First, is it a private lake? If so then no.
Second, what part of the land is public? Someone may own part of the lake, but maybe not all. I forget where I went online to see property boundaries, but I did find it online. (Don't hunt on someone's land!!!)
Is it in a restricted shooting area? Call the Sheriff, and ask if it legal to discharge a shotgun in that area. Calling WDFW will do you no good.
Be safe. Know where houses are!
And have fun
