How access works here
Numbered public access-site network
This water sits in Montana's Fishing Access Site network. Reaches between sites are usually floatable and wadeable below the high-water mark, but you get on and off at the signed sites.
Launch · Many FAS points have a concrete or gravel ramp suitable for a drift boat or raft. Some are hand-launch only — the FAS list says which.
Parking · Parking is at designated access points. A pullout that looks fine is not automatically legal or safe to leave a vehicle in.
Montana runs a numbered Fishing Access Site (FAS) network — most named reaches have signed FAS points with parking, and many have a ramp. Montana also has a stream access law: below the ordinary high-water mark of most rivers is public, but you still have to get there from a public point.
Gauge
A public gauge is mapped
Flow and water temperature for this water are read from USGS site 12304500, Yaak River near Troy, MT. It is an official public gauge, not a fishing pin: it describes the river at one point, and the reach you stand in may be doing something else.
