What the runs do here

South Branch Pentwater 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.

From the National Inventory of Dams (USACE). Hazard potential is a downstream-consequence classification, not a statement about the structure's condition.

The water above and below

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.

Getting to it

Public access sites near the dam, straight-line distance. A dam itself is private property unless its owner says otherwise; these are the places the state lists as open.
