Come July, water temperatures start hitting summer highs, and trout fishing often is regarded as less than "hot." Rising temperatures will often concentrate trout in declining areas of suitable habitat.

As is so often the case, the secret to success largely rests with knowing where to go.

In a state where anglers direct so much attention toward trout fishing, it's hard to imagine that any good trout rivers are left undiscovered.

But yes, there are a few.

Here's a look at some of our best trout rivers, plus a look at one river that's still so lightly fished it could be considered a secret.

CLARION RIVER
The Clarion River is one of the most lightly fished of our state's trout rivers, maybe because it flows through sparsely populated counties.

Or maybe because its old reputation still lingers for poor water quality. But that has changed considerably, and today's Clarion River rates as one of the finer trout rivers in the eastern U.S.

It has all of the necessary ingredients: big trout, good access, a stretch that's large enough to be float-fished -- as well as Special Regulations sections to provide a variety of fishing experiences.

There are three of these Special Regulations sections on the Clarion River and its main branches.

On the East Branch Clarion River, starting 100 meters below the outflow of the East Branch Clarion River Dam downstream for 1.15 miles, is a Delayed Harvest, Artificial Lures Only, Special Regulations section.

Cool discharge from the dam keeps this section in excellent shape for trout through the summer.

The West Branch Clarion River has a 0.5-mile Catch and Release, Fly-Fishing Only, Special Regulations section, from a wire across the stream to the intersection of state Route 219 and state Route 4003.

The Clarion River's main stem has a Catch and Release, All Tackle, Special Regulations section that extends 8.5 miles from the confluence of the East and West branches to the confluence of Elk Creek.

From Ridgway downstream to Cook Forest State Park, float-fishing is popular. Canoe rentals are available at Ridgway and at the park.

Cook Forest State Park has 226 tent and trailer camp sites. For park information, contact the Cook Forest State Park office, P.O. Box 120. Cooksburg, PA 16217; or call (814) 744-8407.
