About Ruby River
Small meadow tailwater below Ruby Reservoir flowing north to the Beaverhead at Twin Bridges. Technical brown trout fishing in low, clear water — public access has been a long-running issue, so know the bridge-access rules before you go.
Regulations
Public access on the Ruby is contentious — Montana stream access law allows fishing below the high-water mark, but landowner conflicts at bridge crossings are ongoing. Use established FWP fishing access sites and stay below the high-water mark.
