Question about tag wording

[sigpros]

When the hunt planner says so and so tag is good within the "blank" river drainage what does that mean? Like is there a written rule like half mile either side of the river? I have always wondered how it applies

Basically the watershed for that river. the actual boundary will be listed in the unit descriptions in the regulations.
