Current USGS flow is 260 cfs and has been stable for about 6 hours. Today's flow is high for this date; the upper end of the normal range is near 259 cfs. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.

Before choosing how to fishCheck the water first
There is not enough reliable current information to recommend wading, bank fishing, or floating.
Check before you drive
Current flow and weather.
Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

Area description
Barnum and Jennings Randolph tailwater
Primary upper flow-reference reach; check dam and rule context before fishing.
Restrictions and seasonal notes
Maryland DNR and Potomac-Garrett sources are better than old pullout descriptions.
Border-water fishing can create rule confusion; check current state rules before harvesting fish.
02No map pin

Westernport and Luke corridor
Lower North Branch context with different gauge value and access planning.
Restrictions and seasonal notes

How to fish it
Choose the reach before choosing flies.
The North Branch Potomac has upper tailwater and lower border-water sections with different gauges, access, and regulation details. Use Barnum for Jennings Randolph planning and Luke for lower context.
- Use the Barnum gauge for upper tailwater planning below Jennings Randolph.
- Check Maryland catch-and-return/artificial-lure rules by boundary and reach.
- The river has powerful current, boulders, and private-property edges.
- Keep West Virginia and Maryland border-water context in mind when planning access.
Why the score looks this way
FlowUse caution
USGS shows 260 cfs with a stable over about 6 hours trend. Today's flow is high for this date; the upper end of the normal range is near 259 cfs. Fishable water may exist, but do not rate it highly without a safe access, clarity, and wading or boat plan.
Short-term weatherUse caution
The forecast has storm or heavy-precipitation risk, so timing and access matter more than the score alone.
Public alertUse caution
A Flood Watch is active near this forecast point, so the score is capped until runoff, clarity, crossings, and road access are checked. NWS alert: Flood Watch issued August 2 at 3:50PM EDT until August 3 at 2:00AM EDT by NWS Baltimore MD/Washington DC.
SeasonHelps score
Early summer: Caddis, mayflies, and stable flows can produce good trout windows.
Water temperatureHelps score
USGS water temperature is about 58F, with no heat stop triggered.
Read the water
What changes the plan.
The North Branch fishes best when cold releases and stable flows create defined lanes without making wading dangerous. If the river is rising or too heavy, fish from safe edges or pick a smaller tributary.
Stable cold release
Nymph deep seams, swing soft hackles, and cover pockets with careful wading.
High release
Avoid mid-channel wading; use bank water or a safer backup reach.
Low clear water
Use longer leaders, smaller flies, and avoid repeated casts over the same fish.
Summer warmth
Check temperature and move to colder water if trout handling becomes risky.
Your trip plan
Know when to go—and when to skip it.
Best flows
Use RiverReports and USGS 01595800 at Barnum for upper tailwater planning, then compare USGS 01598500 at Luke when the lower corridor is part of the day. One gauge does not answer every reach.
When to skip
Skip wading when releases are high or rising, border-water rules are unclear, the access point depends on private land, or boulder current and weather make exits uncertain.
Local plan
Pick upper Barnum or lower Luke context first, check the Maryland special-management rule language, then choose a public access plan through Potomac-Garrett or a known corridor before tying on flies.
Backup water
If the North Branch is too high, crowded, or access-limited, compare the lower Savage, upper Savage, or Big Gunpowder depending on travel range and target species.
Hatches & flies
Bring a flexible box.
TimingWhat to watchUseful flies
March to AprilMidges, early black stones, BWOsZebra midge, black stonefly nymph, BWO emerger, pheasant tail
Fly pattern · report suggests “Zebra midge”Zebra MidgeLook for a very slim tapered thread body, evenly spaced contrasting wire rib, a small bead, and no tail or wing. The reviewed classic is black with silver wire and a silver bead. Red, olive, brown, glass-bead, jig-hook, resin-coated, or tailed forms must remain labeled variations rather than replacing the classic identity.See photos & how to fish it ↗
Fly family · report suggests “black stonefly nymph”Black Stonefly PatternsBlack stonefly wording is a color and insect-group label, not one exact recipe. Size, nymph versus adult stage, wing profile, and weighting must remain explicit.See family guide ↗+ 2 more reviewed guides in the Fly Box April to JuneHendricksons, caddis, March Browns, SulphursHendrickson, elk hair caddis, March Brown, Sulphur comparadun
Fly family · report suggests “Hendrickson”Hendrickson PatternsHendrickson is a hatch name. Nymphs and emergers, upright or low-riding duns, and rusty spent spinners are different fly jobs.See family guide ↗
Fly pattern · report suggests “elk hair caddis”Elk Hair CaddisLook for a tented elk- or deer-hair wing, clipped hair head, dubbed body, rib, and hackle palmered along the body. The body color should be labeled because tiers often match different natural caddis colors.See photos & how to fish it ↗+ 2 more reviewed guides in the Fly Box SummerCaddis, terrestrials, small mayflies, baitfishCaddis dry, ant, beetle, hopper-dropper, small woolly bugger
Fly family · report suggests “Caddis dry”Caddis Patterns by StageCaddis is not one fly. Larvae live below, pupae and emergers rise through the column, tent-wing adults ride or move on top, and spent forms create other silhouettes.See family guide ↗
Fly family · report suggests “ant”Ant PatternsAnt patterns can be foam, fur-bodied, winged, or sunken. The narrow waist and paired body lobes matter more than one material recipe.See family guide ↗+ 2 more reviewed guides in the Fly Box FallBWOs, October caddis, streamer waterBWO dry, soft hackle, October caddis, sculpin, small leech
Fly family · report suggests “BWO dry”Blue-Winged Olive PatternsBWO describes a hatch group, not one fly. Nymph, emerger, dry, cripple, and spinner profiles must stay separate because they occupy different parts of the water column.See family guide ↗
Fly family · report suggests “soft hackle”Soft-Hackle Wet FliesA slim body and sparse webby feather collar define the family. Body material, tail, bead, and insect-specific color create different named patterns.See family guide ↗+ 3 more reviewed guides in the Fly Box 01
Decide whether you are fishing the Barnum tailwater area or lower Luke/Westernport water.
02
Nymph boulder seams and pool heads with enough weight to control depth.
03
Swing streamers and soft hackles through slower tailouts when flows allow.
04
Cross only where you can return safely if releases or weather change.
05
Respect posted private land and do not assume every bank is legal access.

Before you leave.
What should I check first before fishing the North Branch Potomac?+
Check Barnum and Luke flows, the weather forecast, and current Maryland trout special-area rules first.
Are there special regulations on the North Branch Potomac?+
Yes. Several sections have catch-and-return, artificial-lure, and boundary-specific rules.
Is the North Branch Potomac easy to access?+
Some access is practical, but it is a larger border river with private land, boulders, and reach-specific planning.
What flies should I bring for the North Branch Potomac?+
Bring the hatch chart flies, a few confidence nymphs or baitfish patterns, and a backup selection for high, low, clear, stained, cold, or warm conditions.
