Lucy Brook to Artist Falls Brook: the fly-only water
The section that draws people is short and easy to find. From Lucy Brook downstream to the confluence with Artist Falls Brook in Conway the Saco is fly fishing only with a two-trout daily limit, roughly three miles of riffle-and-pool water that Fish Fly Water describes as 50 to 80 feet wide, gravel and small cobble underfoot, riffles running into long deep pools. Access is First Bridge on River Street in North Conway, Davis Park, and Humphrey's Ledge on West Side Road, and the whole reach sits minutes from North Country Angler, the Mount Washington Valley's fly shop. The section is stocked with all three trout and, in Orvis's words, it is also the water that produces exceptionally large browns, fish over twenty inches not uncommon and fish over two feet seen every year. On summer weekends the river fills with tubes and rental canoes out of Conway; My Outdoor Basecamp calls it the rubber hatch and says to be on the water at first light.
Crawford Notch to Bartlett, and the river below Conway
The Saco starts at Saco Lake in the top of Crawford Notch and runs southeast through Bartlett before it reaches the valley towns. Orvis's reporter rates Bartlett to Conway the best stretch and names First Bridge Park on River Street in Bartlett as the top access; there is a second USGS gauge there, at River Street. FlyFishFinder puts the wild fish in the upper river near the notch and in the tributaries. Two of those tributaries are worth knowing: the Ellis River in Jackson is fly-only from the covered bridge down to the iron bridge, and the Swift River joins in Conway. Below Conway the character changes; Orvis describes sandy stretches and log jams as the river slows toward Fryeburg, Maine, and the 8.5 miles from First Bridge to Davis Park is the state's most popular flatwater paddle.
Gray drakes around Memorial Day
One hatch defines this river. Orvis's local report singles out the June gray drake spinner falls as the river's signature, and Fish Fly Water dates them from about Memorial Day into early July, right behind the Hendricksons it calls the best hatch of the year in late May and early June. FlyFishFinder starts the season earlier with Quill Gordons in late April when afternoon water temperatures reach the mid 40s, puts Green Drakes in late June with evening emergences that bring the big fish up, and extends the fall with October olives and autumn caddis on the upper river. In between, Orvis lists caddis, stoneflies and Red Quills, and both sources agree that from July through September hoppers and beetles along the banks carry the fishing, with Tricos on the flats. When flows come up after rain Orvis's advice is streamers with an erratic retrieve, because Saco browns chase before they commit.
From 300 to 3,000 cfs in a day
The Saco is a mountain river and behaves like one. Orvis's reporter says it is not unusual to watch the Conway gauge go from 300 to 3,000 cfs after a storm, and that it falls as fast as it rises. Below 1,000 cfs he calls it easily wade fished; above 1,000 it is a raft river. Fish Fly Water gives the same number, 300 to 1,000 cfs as the wading window at USGS 01064500, with 1,500 and up limiting you to the margins, and this page compares the live gauge to 300 to 1,000. Typical monthly flows from the USGS record at Conway are about 2,600 cfs in April, 2,100 in May, 750 in June, 385 in July, 275 in August, 285 in September and 530 in October, so spring runoff usually keeps the river out of the window until late May. Visibility in normal water is three to six feet, which is why Fish Fly Water and RiverReports both talk about stealth, long leaders and fine tippet; at the 179 cfs low of August 2026 the fishing was sight fishing.
Season, the two-fish rule, and what closes in October
The Saco falls under New Hampshire's general river rules except in the fly-only section. Trout season is January 1 to October 15 with a daily limit of five fish or five pounds, whichever comes first, and no length limit; from Lucy Brook to Artist Falls Brook the method is fly fishing only and the limit is two trout. Like most rivers in the state it is closed to all fishing from October 16 through December 31 unless a special rule says otherwise, and none does here, and fishing from the ice is prohibited. Brook trout in the upper river and the tributaries are wild fish; the fly-only water and the valley reaches are stocked. A New Hampshire license is required; nonresident one-day, three-day and seven-day licenses are sold, and under-16s fish free.
