Pennsylvania has about fifty miles of Lake Erie shoreline and one of the densest steelhead fisheries in North America packed into the creeks behind it. The runs turn on rain, because the creeks are small.
Seasons, limits and licence rules are set by your state agency.
Each bar below spans January to December, with today marked, and draws the quoted sentence underneath it. Where an agency describes a run by season rather than by month, the card carries the sentence without a bar.
Erie County creeks are shale bottomed and shallow, so a run here is a series of pushes after rain rather than a steady arrival. The state agency describes rain raising the tributaries and drawing anglers in behind it.
During October through April, steelhead travel from the depths of Lake Erie to spawn in nearby tributary streams.

The Fish and Boat Commission’s own reference guide splits the year into three periods rather than naming a run: early September to early November, mid November to early March, and early March to mid May. It also gives the thing that actually matters on this shoreline, which is how long a creek takes to drop back into shape after rain: a day or less on the small ones, one to two days on the medium ones, and two to four days on the large ones.
STREAM SIZE & ESTIMATE for FISHABLE LEVELS AFTER RAIN EVENTS
Fish passage counts are published by the programmes that run the counting stations, linked below with what each one reports.
No agency publishes a live or near live count on any Pennsylvania river covered here. The live readings above are river conditions, and the agency linked at the top of the page is the source for run reports.
Run windows on this page are quoted from the agency named beside each one. River conditions come from the U.S. Geological Survey and are readings, not forecasts and not fish counts. Fishing seasons, bag limits, gear rules and licence requirements for Pennsylvania are set by the agency linked here, and a run window is not an open season. For rules, see Pennsylvania Fish and Boat Commission. National picture: every state with a salmon or steelhead run →
