Fly Fishing Castle Rock Creek Wisconsin
Castle Rock Creek, a limestone spring creek, is also known as Fennimore Fork. It is located just east of Fennimore and flows from there into the Blue River. This stream is known for its tough to catch trout but that’s the way a good spring creek should be. It’s very fertile and has a very high pH. The water chemistry provides plenty of food for the trout. Although fly fishing Castle Rock Creek can be a little technical, it’s well worth any serious fly anglers time to fish it.

Most of the stream flows slowly through the meadows and pastures. Its water stay cold and clear except the times excessive runoff ads some color. Castle Rock Spring provides most of the stream water.  

The stream is a little larger than most of the other spring creek in the Driftless area. It has large, often deep pools connected with shallow, fast flowing riffles. The riffles usually have gravel bottoms and the pools have lots of plant growth.

The section from the second bridge on Highway Q upstream to Church Road is “catch and release”, “artificial lures and flies only” regulations.

The river can get a little crowded during the peat season but there’s plenty of trout to catch and the pressure doesn’t hurt the population. This is largely due to the difficulty in catching its stream-bred brown trout.

Its fertile water supports a large number of aquatic insects and crustaceans. There are many different species of baetis species and other similar insects called Blue-winged Olives. It has a huge population of caddisflies including Little Black Caddis, Cinnamon
Caddis, Spotted Sedges and several other species..There are plenty of scuds and sowbugs.
Terrestrial insects are plentiful during the summer months. Under low light conditions, streamers are often effective in fooling the big browns. Fly fishing Castle Rock Creek is a match the hatch challenge for the best of the bug wise anglers. It is also a stream where our Perfect Flies are worth their weight in gold.
