| Window | Reading |
|---|---|
| Too low | Under 20 cfs |
| Low and fishable | 20 - 40 cfs |
| Prime | 40 - 110 cfs |
| High - edges only | 110 - 175 cfs |
| Blown out | Over 175 cfs |
Tannic freestone: runs tea-colored even when clear. Green-tea and falling is prime; milky after floods for 24-48 hours.
Fast for a forest creek: moderate rises clear in about a day; floods take two.
How the bands were set: Working bands derived from USGS daily discharge statistics for station 03011800, 10 years ending Oct 2026: percentiles p10 12, p25 23, median 57, p75 104, p90 168, p95 220 cfs. Small basin, quick moods: the gauge is in the Delayed Harvest reach, so the number is the water.

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 (over 175) | Small basin, fast flood: the DHALO runs milky and pushy for a day or two. | Fish the edges on the fall, or the tributaries. | Streamers on the first drop. | Wait a day. |
| Prime tea-green (40 - 110) | The whole section fishes; wild browns feed across lies. | Walk the full corridor; match the hour's hatch. | Season's sequence. | Go. |
| Low and clear (under 20) | Gin tannic water; wild fish at maximum wariness. | Kneel, cast once, 6X-7X in the pools. | BWO, midges, ants in season. | The hardest, best test. |
| Cold snap | Slow pools glaze at the edges. | Midday midges in the deepest slots. | Zebra midges. | Short sessions. |
| Warm rain | Wild browns slide out of cover on the drop. | Streamers tight to the banks as it falls. | Sculpins, buggers. | Go on the drop. |
| Summer heat (over 68 F) | Even forest water warms in a true heat wave. | Dawn only, highest in the system, thermometer out. | Terrestrials early. | Measure first. |
Access points
Guffey Road Bridge (Rocky Road) - top of the DHALO · Map pin
Parking: Bridge pull-offs at the Guffey Road bridge; National Forest land around the crossing.
The Delayed Harvest Artificial Lures Only section starts here: 4.77 miles downstream to the Allegheny National Forest boundary near Westline (PFBC). The gauge is at this bridge - read it, then fish it.
Westline - bottom of the DHALO · Map pin
Parking: Village of Westline: roadside parking, the Westline Inn for supplies; the creek meets the Allegheny Reservoir arm (Kinzua Bay) just below.
Where the special water ends and the creek dies into the bay. Below Westline is general-regulation water toward the reservoir - lake fish wander up in spring.
Dewdrop reach (below Westline, toward the bay) · Map pin
Parking: Forest Service recreation access at Dewdrop on the reservoir arm.
The creek's last mile is really the reservoir's first cove: spring warmwater and wandering lake trout water more than creek fishing - listed so you know where the creek story ends.
Access changes with postings and seasons — respect every sign, and confirm current PFBC regulations before fishing.
