Caldwell Creek is a tributary of Oil Creek in Warren County and Crawford County in Northwest Pennsylvania. The Creek rises south of Torpedo, then flows south through Warren County into Pine Creek, about one mile northeast from East Titusville.

The upper branch of Caldwell Creek joins the West Branch, forming the main stem of the stream. The West Branch starts at Sanford Corners and gradually becomes wider. It is fed by two tributaries: Middle Branch and Three Bridge Run. There is a catch and release section in this area.

The main stem of Caldwell Creek is heavily stocked and has deep pools. It runs for about ten miles before joining Pine Creek. The entire Creek is well-covered with a canopy of tree limbs, so you won’t have to worry about the water being too warm. 

The holdover brown trout in this stream can get quite large, particularly in the main stem.

Best Spots to Fish Caldwell Creek

You can access the West Branch of the Creek from the bridges on State Route 304 and 357. You will also find smaller roads leading off of the main routes. This will require a bit of a hike, so make sure you are in good shape before you go. You can also access the main stem from Doytville Road. 

The catch and release section is located from the West Branch Bridge to Three Bridge Run. This area is open year round. 

The best place to fish Caldwell Creek is the main stem, as you will find good canopy coverage and large brown trout in this area. The stream is accessible to wade fishermen. 

Stream Flow and Current Conditions

Be sure to check the stream conditions before heading out to fish Caldwell Creek. The USGS stream gauge near Grand Valley, PA provides a good indication of current conditions.

The graph below shows the stream flow (discharge) for the past 7-days. If flows are considerably above or below historical norms (yellow triangles on the chart) then fishing conditions may not be ideal.


    Best Time to Fish Caldwell Creek

    The season for Caldwell Creek is the standard Pennsylvania trout season. However, the catch and release section is open all year.

    Spring is the best time to visit the stream, due to the insect hatch. At Caldwell Creek, you’ll find Mayflies, Caddisflies, and Stoneflies. Additionally, terrestrials are common in the summer. 

    You might also have success tackling this Creek in the fall, as that is when you’ll see the largest brown trout due to the spawn. You can also fish this stream during the summer, as the water remains relatively cool throughout the year.
