What the runs do here
South Br Thunder Bay River carries no anadromous run on our corridor map, so
this page makes no claim about salmon or steelhead at this dam. What it sits on is coldwater —
resident trout water — and the section below says which classification says so.

Simmons Creek
0.43 mi from the dam · Cold stream (MDNR VSEC) · typed Cold
Coldwater designation is the state's own classification. A dam sits on one river and this list
is every designated reach within a mile and a half of it, so a tributary mouth shows up here too.
Water right now
No USGS temperature gauge we read reports within 20 miles of this dam, so
this page has no live number for it. That is a gap in the gauge network, not a judgement about
the water.
