Waters of Maryland

Trout Streams & Rivers

From limestone spring creeks to freestone mountain runs, Maryland offers remarkably diverse trout fishing for every skill level.

Catch & Release

Gunpowder River

Maryland’s most celebrated tailwater. Cold, clear water below Prettyboy Dam holds a dense population of wild browns and rainbows, with exceptional hatches spring through fall.

📍 Baltimore County 🎣 Wild Brown & Rainbow

Wild Trout

Savage River

A remote freestone gem in Garrett County. Native brook trout thrive in the cold, hemlock-shaded headwaters — demanding wading rewarded by pristine wilderness.

📍 Garrett County 🎣 Native Brook Trout

Scenic

Big Hunting Creek

Flowing through Catoctin Mountain Park. Tight casting, classic Appalachian scenery, abundant summer hatches, and an established population of wild brown trout.

📍 Frederick County 🎣 Wild Brown Trout

Trophy Water

North Branch Potomac

A productive tailwater below Jennings Randolph Lake. Consistent flows and cold temperatures hold large rainbows year-round, including through the heart of winter.

📍 Garrett County 🎣 Rainbow Trout

Accessible

Patuxent River

The most convenient option for central Maryland anglers. Stocked throughout the trout season with easy access and family-friendly stretches in Howard County.

📍 Howard County 🎣 Stocked Rainbow

Hidden Gem

Little Gunpowder Falls

A quieter tributary of the main stem, holding browns into summer with lighter pressure. Ideal for exploring with an ultralight rod and small dry flies.

📍 Harford County 🎣 Brown Trout

Entomology & Tactics

Essential Fly Patterns

Match the hatch and fool Maryland's selective trout with the right patterns for every season and stream type.

Spring · May–June

Sulphur Emerger (PMD)

The Gunpowder’s legendary sulphur hatch defines late spring evenings. A size 16–18 Sulphur Comparadun or CDC Emerger fished in the film during the rise is devastatingly effective.

Brook Trout · All Season

Woolly Bugger

The proven streamer choice for Savage River brookies. A dark olive or black Woolly Bugger swung through plunge pools draws aggressive takes from native fish.

Year-Round

Blue-Winged Olive (BWO)

Hatches heavily on overcast, drizzly days from fall through spring. A size 18–22 Sparkle Dun or Parachute Adams is the go-to dry on most Maryland tailwaters.

Winter · Year-Round

Zebra Midge

When no surface activity is visible, a size 20–24 Zebra Midge suspended under an indicator consistently produces on the Gunpowder and North Branch year-round.

Summer · Fall

Elk Hair Caddis

Caddis are prolific on Maryland freestone streams. A size 14–16 Elk Hair Caddis skated across the surface at dusk brings aggressive takes from wild browns.

Seasonal Guide

When & How to Fish Maryland

✓
Spring (Mar–May)
Focus on midday BWO hatches and early Sulphurs. Water temps rise quickly — watch the thermometer carefully above 65°F.
✓
Summer (Jun–Aug)
Fish early morning or evening. Terrestrials — ants, beetles, hoppers — shine in the warmer months on freestone streams.
✓
Fall (Sep–Nov)
Browns become aggressive pre-spawn. Streamers and larger nymphs produce well throughout October and into November.
✓
Winter (Dec–Feb)
Tailwaters stay fishable all winter. Slow, dead-drifted midges through deep pools on cold, sunny afternoons will find fish.
✓
Maryland requires a freshwater fishing license plus a trout stamp. Verify DNR regulations before each outing — rules vary by water.

Early Season BWOs on the Gunpowder — A Promising Start to 2026

Overcast skies and 46°F water temps brought out a steady Blue-Winged Olive hatch from 11am to 2pm. Several browns rising in the riffle above the Falls Road bridge took a size 18 Parachute Adams without much hesitation. Water clarity was excellent and flows were running close to ideal for mid-March…
