Lake Erie tributaries hold cool, steady water into mid-October
Gauge readings around Presque Isle and the Erie tributaries show water in the mid-50s this morning. USGS gauge 04213152 reads 57°F with 8.42 cfs flowing, gauge 04212895 reads 55°F, and gauge 03021890 reads 56°F. A narrow temperature spread across the area points to a stable, settled system. Gauge 04213000 reports 13.8 cfs. Anglers fishing the Great Lakes tributary scene typically look for Brown Trout and Rainbow Trout to move into cooler, flowing water this time of year. Wired 2 Fish's trout lure guide describes working a Great Lakes tributary for brown trout, which fits what these readings suggest.

With a new moon today, expect low-light windows at dawn and dusk to carry the most promise. Dark nights tend to keep fish tucked in cover until the light is lowest, so early morning and the last hour of daylight are the periods worth planning around.
Water in the mid-50s is comfortable for trout and keeps them willing to feed. If the next few days stay cool, those temperatures should hold or ease down slowly, which usually helps tributary trout stay active. A sharp cold snap or a heavy rain would change the picture quickly, so watch the gauges for any jump in flow before heading out.
For technique, Fishing the Midwest notes that fall fish tend to relocate toward living green cover as weeds die back, a pattern worth keeping in mind for any still-vegetated stretches. Tactical Bassin's October content favours jigs, soft jerkbaits and topwater for shallow fall Smallmouth Bass, so those presentations are reasonable to carry along if you work the lake edges as well as the creek mouths.
Context
Mid-October is a transition period for Lake Erie and Presque Isle. Surface water has cooled from summer highs, and tributary flows are usually modest before the late-fall rains. Fish typically start concentrating in predictable spots as baitfish and gamefish respond to the cooling water. Check current Pennsylvania regulations for seasons and size limits before keeping any fish.
