Where the trout water actually ends
Be clear about this before you drive: on the Maine Androscoggin the trout fishery is the upper river, from the New Hampshire line at Gilead down to Rumford Falls, and the reach people call Rumford to Lewiston is a smallmouth river with northern pike below the Livermore Falls dam. IFW's 2014 Upper Androscoggin management plan says so in as many words. It defines the upper river as state line to Rumford Falls, calls the 13.6 miles from Gilead to Davis Park in Bethel the focus reach where anglers target trout, says the Bethel to Rumford Falls water suits browns and bass, and notes that guides target bass in the flatter water above Rumford Falls in summer. Brandon Bichrest of Maine Fly Guide, who has fished it since 1998, floats the Rumford Falls, Livermore and Auburn to Brunswick sections for smallmouth and says seeing one or two other anglers in a day counts as heavy traffic. The 2025 IFW stocking report lists no trout in the main stem anywhere between Mexico and Lisbon.
Gilead to Davis Park: the focus reach
The plan describes the focus reach as swift water over cobble, gravel and sand, averaging four feet deep and 412 feet wide, 47 percent riffle and 35 percent run, with almost no true pools and a shortage of holding cover; the people who fish it called it skinny water. Put-in and take-out are the Bridge Street launch in Gilead and Newt's Landing off Ferry Road in West Bethel, a float of about seven miles that IFW's regional biologist says takes four to six hours with fishing stops and is best in May and June and again from September to mid-November. Walk-in access is thinner than boat access: the old Route 2 bridge approach on the west side of the Wild River gives parking and river frontage near the Wild River mouth, and the state owns undeveloped parcels off the North Road in Gilead and Newry. Most of the rest of the bank is private, and the plan is blunt that publicizing spots has cost access on other Maine rivers.
Bethel to Rumford Falls: browns, bass and the long float
Below Davis Park the river widens and deepens for 22 miles to Rumford Falls, five to seven feet deep over sand, 83 percent flat water and run. Hard-surface launches sit at Moran's Landing off Route 26 in Hanover, the Town of Hanover launch off Route 2, and the Rumford town ramp off Route 2 by the McDonald's. This is where the 2025 stocking goes: 2,000 10-inch browns at Hanover on June 3, 1,200 at Bethel and 300 at Gilead on May 20, 14-inch browns at Gilead and Bethel on May 29, 12-inch browns at Gilead, Bethel, Rumford and Mexico in October, and rainbows at Gilead, Bethel, Mexico and Rumford in May. Brook trout go in at Gilead, Hanover and Bethel too. The plan's scale sampling says the browns in the fishery are essentially all hatchery fish, 92 percent before 2006 and too few afterward to count, while wild rainbows, spawned in twelve Maine tributaries from fish New Hampshire stocked upriver, made up 6 percent of the rainbows sampled after 2006.
The summer temperature problem, and the Rumford gauge
IFW's temperature loggers 4.5 miles below Davis Park showed summer water above the preferred range even for browns and rainbows, with only about 5 degrees of night cooling, which is why the department chose those two species over brook trout and why the fishing calendar has a hole in July and August. Perfect Fly's regular reports from below the dams note that the water leaving the bottom of a dam runs about 39 degrees year-round, so winter fishing happens close to them where it is legal.
USGS 01054500 at Rumford measures what comes through the Gilead to Rumford trout water plus its tributaries, the Wild, Sunday and Bear rivers among them. No shop publishes a wading number, so the 1,500 to 3,500 cfs range on this page is the gauge's own record and should be read that way: monthly medians since 1899 are about 8,000 cfs in April, 6,900 in May, 3,600 in June, 2,400 in July, 2,200 in August and September, 2,600 in October and 3,000 in November. The Gilead riffles wade at the summer numbers; above 4,000 the focus reach is a boat reach; the April and May medians are runoff. The Auburn gauge, 01059000, reads the bass water and runs roughly a third higher.
Zebra caddis in June, mahoganies in October
The one hatch every source names is the alder fly, the big zebra caddis, and Perfect Fly puts the big olive-winged drakes right behind it in late June and early July. Its reports from the river track the rest of the year: Blue-Winged Olives and little brown stoneflies in April, little black caddis and Quill Gordons in May, cinnamon caddis and mahogany duns in September, mahoganies and olives in October as the browns color up, and midges and winter stoneflies below the dams in December and January. March Browns, Light Cahills, Tricos and little yellow stoneflies fill the middle. No river-specific chart with dates exists, so the timing below leans on those dated reports and the Maine pattern, and should be treated as approximate.
Rules that change at the Gilead bridge and Route 232
The 2026 lawbook entry, Androscoggin River, Gilead to Brunswick, opens the river to open water fishing from the New Hampshire border to tidewater all year, January 1 to December 31, then divides it. From the border down to the bridge in Gilead: single-hook artificial lures only and all trout, salmon and togue released. From the Gilead bridge to the Route 232 bridge at Rumford Point: April 1 to September 30 is artificial lures only, one trout a day, 12-inch minimum on salmon, rainbows and browns, and every trout between 16 and 20 inches released alive; October 1 to March 31 is artificial lures only with all trout and salmon released. From Route 232 to the Livermore Falls dam the brook trout limit is two (S-19) with the same 12-inch minimum April 1 to September 30, and the same artificials-only, release-everything winter rule. From Livermore Falls to tidewater it is S-19 and open to ice fishing. The Little Androscoggin, from the Welchville Dam in Oxford to the confluence, is its own year-round entry. The lawbook also points to the fish consumption advisory covering the river from Gilead to Merrymeeting Bay.
