South Fork Snake River is a public river in Bonneville County, Jefferson County and Madison County, Idaho, managed by Idaho Department of Fish and Game. You can fish it on an Idaho fishing licence (steelhead and salmon need separate permits). The Idaho stream-access law lets the public use the bed and banks of a navigable stream below the ordinary high-water mark regardless of who owns the adjacent land; on non-navigable water, check current signage or ask permission. Public access confirmed via marquee water.
One of Idaho's world-famous trout rivers (Henrys Fork of the Snake, South Fork Snake, Silver Creek, Big Wood) — large wild rainbow, brown and Yellowstone cutthroat trout over spring-fed and tailwater flows, some of the most technical dry-fly water in the country.
It runs roughly 66 miles through the Upper Snake region. Anglers here mostly fish for yellowstone cutthroat trout. Live flow and gauge height come from the Snake River Nr Irwin Id USGS station shown below. The nearest other mapped waters on PiscaMaps are Table Rock Canyon Creek and South Moody Creek.

Night fishing: No statewide night-fishing closure in Idaho; many rivers and streams have a Memorial-Day-weekend-to-November 30 general season, and steelhead/salmon/sturgeon water is open only by annual rule — check the current IDFG fishing seasons and rules for this water.
Boats: The big lakes and reservoirs (Pend Oreille, Coeur d'Alene, Cascade, Dworshak, American Falls, C.J. Strike) take trailered boats via a state or Forest Service ramp; alpine lakes are hike-in float-tube water and rivers are drift-boat or raft.
Bank & bivvy camping: Idaho is around 63% federal land — dispersed camping is allowed on most BLM and Forest Service ground along these waters, alongside developed Forest Service, state-park and IDFG-access campgrounds.
Tackle: Idaho's general trout limit is 6, but a large number of waters are managed as wild-trout, quality, trophy or catch-and-release with reduced limits and gear restrictions; bull trout are catch-and-release statewide and steelhead/salmon need separate permits and annual seasons. Check the current IDFG rules for this water.
Boat ramps: 10 mapped — Put-in, Put-in, South Fork of the Snake River: Conant Boat Access, Boat ramp, Put-in, South Fork of the Snake River: Byington Boat Access and others nearby.

Anyone 14 or older needs an Idaho fishing licence — the resident annual is about $30.50, the non-resident annual about $98.25 (Idaho's non-resident fee is one of the highest in the country), with a non-resident 1-day (~$23.50) plus $6/consecutive-day option. Steelhead and salmon each need a separate permit. Idaho residents 65 and older buy a reduced-fee licence; under-14 fish free with a licensed adult. Buy from IDFG at idfg.idaho.gov. An Idaho fishing licence covers this water — it is on IDFG's public-waters hydrography (steelhead and salmon each need a separate permit).
