White Haven to Jim Thorpe: the gorge
The trout water starts where the river leaves Francis E. Walter Dam and runs about 35 miles to Walnutport, and the top half of that is the Lehigh Gorge. Wade access in the gorge is by named pull-ins and trailheads: the dam itself, the I-80 bridge at White Haven, Tannery, Hayes Creek, Leslie Run, Rockport and the Glen Onoko boat ramp above Jim Thorpe. Between those points the D&L Trail runs the bank, so a bike turns a short stretch into a long day.
This is the coldest part of the river and the part where wild browns are most reliably wild. It is also the hardest to wade. The bottom is slick, bowling-ball rock, the current pushes even at moderate flows, and the class III rapids that draw the rafters are in here. Studded boots and a staff are not optional, and the Lehigh Coldwater Fishery Alliance puts a warning to that effect at the bottom of its wade chart.
Jim Thorpe to Walnutport: the float water
Below Jim Thorpe the valley opens, Route 248 follows the east bank and the ramps come close together: Jim Thorpe, Packerton Yards, Lehighton (the sewer plant lot), the Pohopoco Creek mouth, Bowmanstown, the Palmerton horseshoe, Lehigh Gap and the Walnutport canal ramp. This is where the guide services run drift boats and framed rafts, and it is where the Lehigh River Stocking Association puts most of its fish. Wild East Outfitters guides it from mid March until the water warms in late June, then comes back in early October.
Cold tributaries matter here in summer. Pohopoco Creek comes in below Lehighton out of Beltzville Lake, and the mouths of Hickory Run, Mud Run, Drakes Creek and Aquashicola Creek all pull trout when the main river climbs into the high 60s. Fish them, but note that Hickory Run below Saylorsville Dam is catch and release artificial lures only and Mud Run inside Hickory Run State Park is delayed harvest.
What the Corps is releasing this week
The Army Corps of Engineers publishes a Francis E. Walter recreation plan every year and it decides your trip. The 2026 plan lists 24 whitewater release weekends from May 9 through the first weekend of September, with October 9 and 10 penciled in if storage allows. Do not plan to wade fish a whitewater release day; the river comes up hard and the boaters own it. The plan also lists 22 fishing enhancement releases: sixteen weekend days from March 21 through May 17 with a target of up to 400 cfs, and six September days (12, 13, 19, 20, 26, 27) at a 350 cfs target, run as a continuous 36-hour block from 1 a.m. Saturday to 1 p.m. Sunday.
The Corps also matches outflow to inflow once the pool hits its seasonal target, so a wet week in the Poconos will show up at the dam whether or not a release is scheduled. Check the dam schedule page and the Lehighton gauge together the night before.
Reading the Lehighton gauge
The wade chart everyone uses, from the Lehigh Coldwater Fishery Alliance, is keyed to the Lehighton gauge. Under 250 cfs is ideal wading anywhere on the river and very hard floating. From 250 to 500 wading is still good everywhere. From 500 to 750 wading is good but the water starts to push, and floating gets good. Between 750 and 1,000 wading is limited to certain sections and the float fishing is at its best. Above 1,000 you are on the bank; above 1,400 the LCFA says do not wade; above 2,200 it says stay home and tie flies or fish the tributaries.
This page compares the live gauge to 250 to 750 cfs, which is the LCFA's good-wading band. The LRSA draws its lines a little differently (under 800 ideal for wading, 800 to 2,500 boat only, boating difficult under 500), and DIY Fly Fishing notes the river fishes best around 200 to 300 cfs close to the dam and up to 750 cfs down toward Lehighton and Walnutport. Read the number against where you plan to stand.
Wild browns, LRSA fish and the cold-water fight
Wild brown trout reproduce throughout the Lehigh, and the biggest of them come out of the gorge on streamers in April and again in October and November. Rainbows and more browns are stocked by the PFBC between White Haven and Jim Thorpe, by the LRSA from Bowmanstown down to the Cementon Dam, and by the Five Mile High Club; the 2017 Fisherman article put the LRSA's annual stocking at about 8,000 fish, some of them 18 to 25 inches. Smallmouth take over below Cementon, and there are stripers and walleye in the lower river.
The LRSA hatch chart runs Little Black Stoneflies February to April, Hendricksons in April, caddis April through October, March Browns, Sulphurs and Light Cahills in May, Green Drakes May and June, Isonychia late June through September and Blue-Winged Olives spotty all summer and heavy in fall. Wild East adds Quill Gordons and Grey Fox to the spring list and calls April 1 to June 15 prime time. Tricos come off in the mornings from Lehighton to Bowmanstown in July and August.
The two year-round sections and the rest of the river
Two pieces of the Lehigh are listed in the 2026 PFBC summary as Stocked Trout Waters Open to Year-Round Fishing: from the Carbon/Luzerne county line at the outlet of F. E. Walter Reservoir downstream to the confluence with Sandy Run, and from 0.33 mile upriver of the railroad bridge at Glen Onoko downriver to Mauch Chunk Creek. On those two reaches you can fish every day of the year with a trout permit; regular season limits apply from the April 4 opener through September 7, extended-season limits (3 trout) from January 1 to February 15 and September 8 to December 31, and from February 16 to opening day you may fish but not keep a trout.
Everywhere else on the Lehigh above the first dam at Easton the statewide inland rules apply: 7-inch minimum, 5 trout from 8 a.m. on April 4 through September 7, 3 trout in the extended season, closed to trout fishing from February 16 until opening day. There is no artificial-lures section on the main river. Confirm the year-round boundaries in the current summary before you go.
