Shawmut: what collapsed, and what is left
The tailwater below Shawmut Dam in Fairfield and Benton was, in the 1990s, the brown trout water people drove across New England for. Maine IFW's own study puts catch rates between 1993 and 1998 at 0.10 to 0.18 legal browns per angler hour, says 3 to 4 pound fish were common, and describes dozens of anglers on the water on a given evening. Just before 2000 it began to slide, and by 2004 the department says the fishery had collapsed. IFW's 2013 to 2016 telemetry and creel work found no single cause: warming water, harsher winters, wilder flows, weaker hatches, and a river filling with competitors, from smallmouth and fallfish to the shad, alewives and stripers that fish passage at Lockwood, Hydro-Kennebec, Shawmut and Weston brings.
What is left is a fishery IFW calls a fraction of what it was, propped up by fall yearlings. The 2025 stocking report lists 2,000 8-inch browns at Fairfield on May 14 and 1,000 10-inch fish on June 13; no rainbows are listed for the Kennebec that year, so the rainbows that still turn up are holdovers or drop-downs. The study also settled where to fish: browns stocked at the dam stayed within about two miles of it and never showed up below the I-95 bridge, while fish stocked at the downtown Fairfield launch either sat there or slid 2.5 miles down to the Hydro-Kennebec pool in Winslow. Since 2019 the department has said future stockings go in at the dam. There is a launch at the dam on the west side and a footpath to it from Benton on the east, and in low summer water people wade across the whole river. Blue Heron Fly Fishing in Gardiner calls Shawmut a good brown trout fishery until the water warms in late June, then a fall fishery on size 20 to 26 Blue-Winged Olives.
Skowhegan, Madison and Solon: the browns most people drive past
Kennebec River Angler's old shop write-up, still online at Total Fly Fishing, is the best reach-by-reach description of the middle river. Five miles south of Skowhegan the river drops through a mile-long gorge into the Great Eddy, which stays cool, holds stocked browns and has tiny Blue-Winged Olives into early winter; the public launch just west of Wesserunsett Stream is the way in. At The Pines in Madison the shop described almost two miles of continuous riffles, pools and drops between the Powerlines pool and the lower Madison dam, with walk-in parking and easy wading in all but the highest water. Above the upper Madison dam the Solon reach is float water, five miles or more of islands and channels from the Route 201A bridge down to the Dump Road launch in North Anson, and Blue Heron calls it one of the only Maine rivers holding browns, rainbows, brook trout and salmon together. The 2025 report shows 1,750 browns at Solon and 3,850 at Anson on May 20, plus 800 at Skowhegan.
Bingham is the wild rainbow water. Wade access is at Wyman Dam, the powerlines below it on the west shore, the mouth of Austin Stream and the old railroad grade south of the Gadabout Gaddis airstrip, and the marble-sized gravel plus the dam's releases make this the hardest reach to wade. Nothing is stocked above Solon, so every rainbow, salmon and brook trout from Wyman Dam up is wild.
Harris Station to The Forks
Above Wyman Lake the river runs along Route 201 from Caratunk to The Forks and then into the gorge below Harris Station, the Brookfield dam holding Indian Pond. The shop described Caratunk to The Forks as miles of wade-in riffle for wild brook trout and landlocked salmon, reached almost entirely from the Route 201 side, with a canoe put-in at the ball field above the Route 201 bridge; fish stack where any stream enters, and the mouths of Cold Stream and Moxie Stream, off the Moxie Falls trail, are the ones every write-up names. The gorge itself is rafting water: Northern Outdoors says turbine-test releases push 8,000 cfs, nearly double a normal whitewater release. Fish very early or very late, in the low-water windows, and watch for rising water the whole time.
USGS 01042500, Kennebec River at The Forks, reports and sits above the Dead River confluence, so it reads what Harris Station is releasing and nothing else. Its monthly medians run about 2,400 cfs through the summer, which is generation, not wading water; the fishing happens in the troughs between releases, and Brookfield's Safe Waters schedule is what to check. This page reads North Sidney instead, because Shawmut is the reach with the road access and the stocking.
Reading North Sidney for Shawmut
USGS 01049265 at North Sidney is below Waterville, so it counts Shawmut's release plus the Sebasticook, which enters at Winslow. No shop publishes a wading number for it. The 3,000 to 6,000 cfs range on this page is drawn from the gauge's own record and should be read that way: monthly medians since 1978 are about 20,800 cfs in April, 12,500 in May, 7,900 in June, 4,700 in July, 4,500 in August, 5,000 in September and 6,000 in October. Below about 6,000 the Shawmut bars are wadeable; the wade-across-the-river summer happens in the July to September trough; anything over 10,000 is runoff or a storm.
Two rule sets, split at the Skowhegan rest area
The 2026 IFW lawbook lists the river in two entries. Kennebec River, Skowhegan to Augusta, covers everything below the red markers near the Skowhegan rest area: from those markers to the upstream side of Lockwood Dam in Waterville and Winslow it is artificial lures only, open to ice and open water fishing January 1 to December 31, with a total daily bag limit of two trout and landlocked salmon combined and a 12-inch minimum length limit; there is no closed season on this reach. Under-16 anglers may use worms from the rest area markers to Shawmut Dam and from the I-95 bridge to Lockwood. From Lockwood down to the power lines above the Calumet Bridge in Augusta, the head of tide, the same two-fish, 12-inch, single-hook artificial rule applies, and striped bass caught May 1 to June 30 must be released.
Upstream, Kennebec River, Indian Stream Twp to Skowhegan, is North Zone water. From Indian Pond Dam to the upstream side of the Abenaki (lower) Dam in Madison it is closed to ice fishing, artificial lures only from April 1 to October 31, two trout and salmon combined, with minimums of 18 inches on rainbows, 14 on brook trout and 12 on browns and salmon. From the Abenaki Dam to the Skowhegan rest area markers it is artificial lures only year-round, two fish, 12 inches. The tributaries from Wyman Dam in Moscow to Williams Dam in Solon, Austin Stream included, are closed until June 1, and the lawbook flags a fish consumption advisory for the whole river from the Carrabassett inlet to The Chops.
