Also called Castle Rock Creek.

73 NHD reaches, 26.9 miles of drawn channel — side channels and braids included, so more than the distance downriver.

What it is

A limestone spring creek northeast of Fennimore, labelled Fennimore Fork on the maps and called Castle Rock Creek by most of the people fishing it. One of the first Wisconsin streams to carry catch-and-release regulations, and still among the few where every trout goes back. The regulation covers part of the stream, not all of it — the extent above is the agency's wording. What is drawn here is the whole named stream, because there is no boundary anywhere we could check it against.

All trout caught shall be immediately released; only artificial lures may be used. Roughly six and a half miles of designated trout water from Church Road.

Where it is

This name covers a stretch whose boundaries are posted on the ground rather than held in any file this site reads, so the map draws the named stream and the boundaries are described in words above rather than guessed at with a line.

No access site in this state's file falls within 3 miles of the mapped reach.

Regulations on this stretch

All trout caught shall be immediately released; only artificial lures may be used. Roughly six and a half miles of designated trout water from Church Road.

Rules change every year and the posted signs are the authority, not this page. Check the current Wisconsin regulations before you fish. Where this stretch sits inside a larger river, that river's general regulations apply everywhere this stretch's do not.

Best times

A spring creek, so it runs cold in August and open in January — the early catch-and-release season is fished here as hard as the regular one.

Live water temperature

No USGS temperature gauge we read reports within 25 miles of this stretch, so this page has no live number for it. That is a gap in the gauge network, not a judgement about the water.
