Gauge: USGS 04213152 — Walnut Creek Upstream Pool, near Erie, PA
Reading baked into this page when it was last updated at 2026-10-14 20:30 — checking the live USGS feed now…
| Window | Reading |
|---|---|
| Too low | Under 15 cfs |
| Low and fishable | 15 - 50 cfs |
| Prime | 50 - 150 cfs, falling, green |
| High and fishable (falling only) | 150 - 250 cfs |
| Blown out | Over 250 cfs, or rising and chocolate |
This is the one Erie trib with a turbidity sensor on the gauge. Practical overlay (consensus): under 2 FNU is gin clear, roughly 2-10 FNU clear green, 10-40 FNU green to stained. Prime clarity is the magic green: about 18-30 inches of visibility.
Small, rocky basin - clears faster than most Erie streams. PFBC classes Walnut as Medium (1-2 days to fishable after a rain event); after a moderate rain it often greens up within a day.
How the bands were set: Angler/guide consensus bands anchored to USGS daily statistics for station 04213152 (18 years of record; mid-October median daily flow 18 cfs). Working numbers, not instrument ratings.

Season playbook
Resolved from today's date — the current season is highlighted. On the live site this re-resolves in your browser.
Fall (Sep - Nov)This season
The water: First pulses on rain in Sep-Oct; by November the creek can hold fish top to bottom on good water. Color cycles fast - plan around the drop into green.
Fish present: Steelhead building to peak; stray salmon early; browns in lower pools.
How to fish it: Mouth and lower pools early season; follow fish up after each rise. Egg patterns rule.
Winter (Dec - Feb)
The water: Low, clear, cold; slush on the coldest snaps. Fish go deep and slow.
Fish present: Steelhead (holdovers and winter fish).
How to fish it: Deepest holes, smallest offerings, midday windows. Manchester-area engineered pools hold the most fish - mind the posting.
Spring (Mar - Apr)
The water: Snowmelt and rain keep flows up; sucker run crowds the creek mid-spring.
Fish present: Fresh steelhead, dropbacks, suckers.
How to fish it: Sucker Spawn and egg patterns behind spawning suckers; dropbacks hit shiners and streamers on the swing.
Summer (May - Aug)
The water: Low and warm in the creek; the action moves to the mouth and marina.
Fish present: Smallmouth, catfish, panfish at the mouth; few steelhead.
How to fish it: Fish the lake side of the mouth at dawn and dusk; leave the creek fish alone in warm water.
On now — hatch & forage for October
- Salmon egg drift (chinook and coho strays) — Glo-Bug, Clown Egg, bead eggs
- Steelhead egg drift (peak run) — Glo-Bugs, single-egg patterns, egg sacks (bait)
- Emerald shiners — Emerald Shiner streamer, White Death, Clouser-style minnows
- Crayfish — Crayfish patterns, Woolly Buggers
Full calendar
| Item | Window | Size | Patterns | Notes |
|---|---|---|---|---|
| Salmon egg drift (chinook and coho strays) | Sep - Nov | eggs 6-10 mm | Glo-Bug, Clown Egg, bead eggs | Early fall: steelhead in the lower creek key on eggs below spawning salmon. |
| Steelhead egg drift (peak run) | Oct - Dec | eggs 6-10 mm | Glo-Bugs, single-egg patterns, egg sacks (bait) | The main event. Fresh fish eat eggs first, questions later. |
| Emerald shiners | Sep - May | 2-3 in baitfish | Emerald Shiner streamer, White Death, Clouser-style minnows | Lake shiners stack at the mouth and in the lower pools all season. |
| Midges | Nov - Mar | #20-26 | Zebra Midge, midge pupa patterns | What the creek's own insects offer in winter: tiny and reliable on clear cold days. |
| Little black stoneflies | Jan - Mar | #16-20 | Black stonefly nymph, small black bugger | Winter staple hatching on mild afternoons. |
| Sucker spawn (white sucker and redhorse) | Mar - May | eggs 6-8 mm | Sucker Spawn (pale cream/yellow) | Spring: steelhead and dropbacks feed behind spawning suckers in the riffles. |
| Steelhead egg drift (spring) | Mar - Apr | eggs 6-10 mm | Egg patterns, beads | Spawning steelhead put eggs in the drift through the spring season. |
| Crayfish | May - Oct | #6-10 | Crayfish patterns, Woolly Buggers | Resident forage in the creek; summer smallmouth food at the mouth. |
Weather & conditions playbook
The row matching the live flow band is highlighted when the gauge answers.
| Condition | What changes | Tactics | Flies | Verdict |
|---|---|---|---|---|
| High and off-color (rising or chocolate) | Gauge over 250 cfs or turbidity spiking: fish slide to bank edges and the lake. | Stay home or fish the mouth from shore. Be first back as it falls through 250 into green. | Big, bright eggs and buggers for the first fishable hours on the drop. | Mostly stay home - set up for the drop. |
| Prime green and falling | 50-150 cfs and dropping into 18-30 inches of visibility: the whole creek turns on. | Cover water. Fish move and eat; this is when mid-creek easements shine. | Eggs first, then nymphs and swung buggers. | Go. Best window on the creek. |
| Low and clear (under 15 cfs) | Gin-clear, spooky fish; most of the run stages in the lake and at the mouth. | First and last light at the mouth; in the creek, deepest slots only, long light leaders, downsized patterns. | Single eggs, small nymphs, midges. | Creek is a waiting game - fish the mouth. |
| Cold snap (water under 38 F) | Fish go lethargic and deep; slush ice some mornings. | Sleep in. Fish the warmest midday hours in the deepest, slowest holes. | Small eggs and midges, dead-drifted slow. | Short, targeted sessions only. |
| Warm rain on a warming trend | A fall warm rain is the starting gun: fresh fish pour in on the rise and spread on the drop. | Fish the mouth on the rise, the lower pools as it greens, mid-creek a day later. | Eggs and bright buggers. | Go - and plan the next two days around the drop. |
| Post-front (bright, high pressure) | Clearing skies and dropping temps push fish into shade and deep slots. | Shade lines, undercut banks, first light. Downsize and slow down by midday. | Natural eggs, small nymphs. | Fishable - adjust expectations and timing. |
Access points
Walnut Creek Marina and PFBC Access (the mouth) · Map pin
Parking: Large PFBC lot at the marina, 241 Manchester Rd, Fairview. Ramps, fish-cleaning station.
Fish the mouth pool and the lake shore. The USGS gauge sits at the upstream pool right here, so the number you checked online is the water in front of you.
Manchester Hole and the falls · Map pin
Parking: Very limited roadside parking; much of the bank is private.
The famous stacked-fish hole below the falls. WARNING: landowners posted property at the hole in fall 2025 after repeated angler misconduct - access is restricted and may be closed; fish only where you are certain you are on public water or easement, and respect every posted sign. PFBC cut a fish-passage trough around the falls in 2026, so fish now spread farther up. Special hours apply on Walnut from Route 5 to the Manchester Road bridge (see Regulations).
Dutch Road tubes (PFBC easement)
Parking: Small PFBC easement parking near the Dutch Road crossing, Fairview Twp.
Public fishing easement (312 ft, both banks, acquired 2026) at the tubes area - part of PFBC's push to open mid-creek water. Quieter than the lower pools.
Sterrettania - Route 832 bridge · Map pin
Parking: Village of Sterrettania; park in designated areas only, not on lawns or posted ground.
Mid-creek public stretches and easements around the Route 832 crossing. Fish run this far mainly on good water; pressure drops off sharply up here.
Asbury Woods and Millcreek Township easement corridor · Map pin
Parking: Asbury Woods and Bridger Park (Millcreek Twp) parking with a footpath to the creek.
PFBC easements: Asbury Woods Partnership (730 ft, both banks) and a 3,600 ft Millcreek Township easement with parking and footpath at Bridger Park. New water worth learning now that the falls bypass passes fish up.
Access changes with postings and seasons — respect every sign, and confirm current PFBC regulations before fishing.
