About West Branch Penobscot
Below Ripogenus Dam — arguably the best landlocked salmon river in the eastern United States. Cold tailwater fed by Brookfield Renewable releases produces large wild salmon and brook trout in dramatic gorge water. The smelt run in May and the fall salmon push are the marquee windows. Remote, scenic, and unforgiving — the standard against which other Maine salmon water gets measured.
Regulations
Maine fishing license + separate Inland Salmon license required. Heritage Brook Trout watershed; slot limits apply on sections — check Maine DIFW for current regs. CAUTION: Gauge 01027500 at Millinocket reads ~15 miles downstream of the prime gorge water and integrates flows after the Debsconeag lakes — use it for trend, not precise gorge conditions. For actual release info, consult the Brookfield Energy / Great Lakes Hydro release schedule for Ripogenus Dam.
