The run corridorThe mouthSpringville Dam — the run stops here
The colour is this river's run stage today, read off NYSDEC
run-timing guidance. Where along the corridor the fish are is not
modelled here — only the sixteen rivers the staging estimator covers
carry that.
Drawn 30 September 2026, north up, and it is a map of the river rather
than of the lake it runs from.
2 species run Cattaraugus Creek out of Lake Erie — steelhead and lake-run brown trout. The corridor is 35.7 miles of run water over 92 NHD reaches, from the harbour mouth up to Springville Dam. As of 30 September 2026, steelhead is at tail-off and lake-run brown trout is at staging.

The run species, one by one
Every species the corridor file records on this river, with the field mark that calls it at
the net. Windows are New York's curated guidance; a species that runs twice on one
calendar carries both entries.
Steelhead — lake-run rainbow trout
A chrome rainbow off the lake, the stripe faint on a fresh fish and loud on one that has wintered in the river.
Two runs on one calendar: a fall push that winters in the river and a spring run onto the gravel. The fall fish are the reason a January river is not empty.

Sept–May
Size
Five to twelve pounds, and bigger on the Manistee-type rivers.
Buttery flanks with black and red spots, and no spotting on the tail worth the name — the mark that separates it from everything else in the run at the net.
Runs with the autumn steelhead and behind the salmon, and is the most nocturnal fish in the corridor. Many hold over into February and March.
