Check Safe Waters before you rig up
Open Brookfield Renewable's Safe Waters page for Stewarts Bridge before you leave the house. It lists the live total flow below the powerhouse and a short-term release schedule, and on September 24, 2026 that schedule read 2,000 cfs from 7 a.m. to 10 p.m. and 350 cfs from 10 p.m. to 6 a.m., repeating the next day. Brookfield's own warning on the page is that schedules change without notice with weather and power demand, and that water can be released at any time. The page also gives a toll-free Safe Waters hotline and a number for the river manager, who handles questions about rafting releases.
That on-off pattern is the whole story of fishing this river. At the 350 cfs base the lower Sacandaga is a walkable river of ledges and runs. At 2,000 cfs it is a rafting run, and the rafts are on it: Wild Waters Outdoor Center puts in at the base of the Stewarts dam for a 3.5 mile Class 2 to 3 trip through rapids its guides call Vesuvius, the Dragon's Back and Sonni's Hole, with a mile-long calm swim section in between.
Conklingville, Stewarts Bridge and the run to Hadley
Two dams control everything here. The Conklingville Dam in the Town of Day, finished in March 1930 for $12 million, holds back Great Sacandaga Lake; below it the river passes the Stewarts Bridge dam and powerhouse, and from there it runs down to the Hudson River at Hadley, on the line between Saratoga and Warren counties. The USGS gauge on this page, 01325000, is at Stewarts Bridge, so it reads almost exactly what the powerhouse is sending downstream.
No shop publishes a wading range for this gauge. The 350 to 900 cfs band used here runs from Brookfield's scheduled overnight base flow up to 895 cfs, the lowest monthly median in the USGS record since 1930, which falls in April while the lake refills. The other months sit near or above 1,800 cfs, from 1,780 in September to 2,776 in February, which tells you that typical daytime water is release water. The highest flow since the lake was built was 16,500 cfs on May 2, 2011.
What lives below the dam, and what DEC does not stock
Be clear about what this reach is. DEC's actual-stocking records since 2011 list no trout for the Sacandaga River in Saratoga, Warren or Fulton counties, and no fisheries survey of the Stewarts Bridge reach turned up in the sources for this guide. What DEC does stock is the lake above: its 2025 records show more than 60,000 rainbow trout going into Great Sacandaga Lake. The lake itself holds walleye, northern pike, smallmouth bass, rock bass, brown trout, landlocked salmon, smelt and yellow perch, and it produced the North American record northern pike, 46 pounds 2 ounces, caught by Peter Dubuc on September 15, 1940.
That makes the lower river a place to fish the base flow with an open mind: crayfish and sculpin patterns and small streamers for smallmouth in the ledges and pocket water, and a nymph rig in the heads of runs for whatever trout have come down. Plan on the evening and early morning, when the schedule drops back toward 350 cfs, and get out of the channel when you hear or see the water come up.
Wells: where the stocked trout are
If trout are the goal, drive north past the lake. Above Northville the Sacandaga is a river again, dammed only at Lake Algonquin, running down from Lake Pleasant and Speculator over Christine, Austin and Auger Falls to Wells, then through Lake Algonquin and on past Hope into the lake. DEC's 2025 records show 4,410 brown trout stocked in the Sacandaga at Wells, most about 9.6 inches with a smaller batch at 14.2, and 1,230 rainbows in the West Branch Sacandaga. For that water, use USGS 01321000 near Hope, which sits 4.5 miles upstream of the hamlet, well above the big lake.
Statewide rules below Stewarts, a spring closure near Northville
The lower river has no entry on DEC's Region 5 special regulations list or its trout stream special regulations, so statewide rules apply. For trout in streams that means April 1 to October 15, 5 a day with no more than 2 over 12 inches, and catch and release with artificial lures only from October 16 through March 31. Black bass may be kept June 15 through November 30 at 12 inches and 5 a day; walleye May 1 through March 15 at 15 inches; northern pike May 1 through March 15 at 18 inches.
Upstream, the Region 5 list closes the Sacandaga from the Bridge Street bridge in Northville up to the first crossing of Route 30 from March 16 through April 30, and closes the lake's other tributaries from their mouths up to the first road bridge for the same weeks. Both rules sit in the Fulton and Hamilton county listings.
