Unit boundary

Simplified for the web from Washington Department of Fish and Wildlife's public layer (source and terms). Units change with each season's regulations, and the legal boundary description in the regulations is what counts.

Turkey, waterfowl, some public lands and opening days have their own hours. Always check the Washington regulations for your species (where this rule comes from).
