Bitterroot River is a public river in Ravalli County and Missoula County, Montana, managed by State of Montana (public / navigable water). You can fish it on a Montana fishing licence; bank access is at bridge crossings, MTFWP access points and public parks. Montana riverbeds are private property up to the ordinary high-water mark except on a few federally-declared-navigable reaches, so wading or bank fishing away from a public access point needs the landowner's permission. Public access confirmed via marquee water.
One of Montana's world-famous Blue Ribbon trout rivers (Madison, Big Hole, Beaverhead, Bitterroot, Gallatin, Missouri below Holter) — wild and stocked rainbow and brown trout, westslope cutthroat, and mountain whitefish, with catch-and-release and special-regulation stretches on the best water.
It runs roughly 54 miles through the Northwest Montana region. Anglers here mostly fish for rainbow trout, brown trout, westslope cutthroat trout, mountain whitefish. Live flow and gauge height come from the Bitterroot River near Darby MT USGS station shown below. The nearest other mapped waters on PiscaMaps are Big Creek and Willoughby Creek.

Night fishing: No statewide night-fishing closure in Montana, though many Blue Ribbon trout rivers have seasonal 'hoot owl' restrictions (afternoon/evening closures) during hot, low-water summer conditions to protect stressed trout — check current FWP drought restrictions before an evening trip.
Boats: Flathead Lake, Fort Peck Lake, Canyon Ferry and the other big reservoirs take full-size boats; most Blue Ribbon trout rivers (Madison, Big Hole, Beaverhead) are floated by drift boat, raft or canoe. An AIS watercraft inspection is mandatory for all trailered boats moving between waters.
Bank & bivvy camping: Camp at MTFWP Fishing Access Sites (many allow camping, some are day-use only — check the site listing), Montana state parks, and National Forest campgrounds along the trout rivers.
Tackle: Trout limits vary widely by water and are often catch-and-release or reduced-limit on the famous Blue Ribbon rivers; walleye/northern pike/bass limits on the reservoirs are more generous. Always check the current MTFWP fishing regulations for this specific water — Montana's regs are unusually water-specific.

Anyone 12 or older needs a Montana fishing licence — the resident annual (Conservation License + fishing) is about $34, the non-resident annual about $150, with non-resident 2-day (~$35) and 10-day (~$75) licences also sold. A separate Aquatic Invasive Species (AIS) prevention pass fee applies to residents and non-residents alike. Montana residents 62 and older, and legally blind residents, pay a reduced fee. Buy from FWP at fwp.mt.gov. A Montana fishing licence covers this river under the state's stream access law, which grants the public the right to use rivers and streams for recreation up to the ordinary high-water mark on any water capable of recreational use, regardless of who owns the streambed — one of the most angler-friendly access laws in the country.
