Little Mahoning Creek in Pennsylvania

Little Mahoning Creek is used to being underestimated. It isn’t famous, but it does provide decent trout fishing. The Creek boasts a Catch-and-Release—fly Fishing Only Section and flows through scenic pastures.

If you find yourself in Southwest Pennsylvania, you’ll want to take some time to enjoy the Little Mahoning.

About Little Mahoning Creek

Fly fishing Little Mahoning Creek in southwest Pennsylvania

Little Mahoning Creek (known locally as the “Little Mo”) is a tributary of Mahoning Creek that begins at Deckers Point and flows into Nashville. The headwaters, which are stocked, get as wide as thirty feet. The upper section of the Creek runs through beautiful pastures, with trees and bushes lining the banks.

Additionally, the Creek has large, deep pools that provide good hiding places for trout. The rock substrate is excellent, and there are fast-flowing runs and riffles. You will likely see brown, brook, and rainbow trout here. While the Creek has had its share of problems with water quality and poaching, it is still a fine fishery worth checking out.

Best Places to Fish Little Mahoning Creek

The stream is accessible from State Route #1038, which grants access to the headwaters section. Bridges and side roads along this route also provide entry. 

The best place to fish in Little Mahoning is in the Catch-and-Release—Fly Fishing Only section, which is located just below Nashville. This four-mile section runs from Cesna Run downstream to State Route #1034 at Rochester Mills. 

Stream Flow and Current Conditions

Be sure to check the stream conditions before heading out to fish. The USGS stream gauge near McCormick, Pennsylvania, provides a good indication of the current conditions of the creek.

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

There aren’t any area fly shops or guides (that I know of) that can provide a Little Mahoning Creek fly fishing report.

Fishing Regulations

Pennsylvania requires all anglers 16 and older to have a standard fishing license and a special permit for trout fishing, which can be obtained online or in most sporting goods stores in the state.

A portion of Little Mahoning Creek is managed under Catch-and-Release – Fly Fishing Only (CRFFO) regulations. This section runs from Rochester Mills, 4.1 miles upstream to Cesna Run.

Little Mahoning Creek fishing regulations are available on the Pennsylvania Fish and Boat Commission website.

The nearest airport to Little Mahoning Creek is the Pittsburgh International Airport, about an hour and a half away from the stream. Another nearby option is Allegheny County Airport, which would only add five minutes to your drive. Remember that you can travel to any major or municipal airport in Western Pennsylvania and arrive at your destination after a few hours of scenic driving.

There are plenty of excellent camping options in Southwest Pennsylvania. Milton Loop Campground is only a ten-minute drive away. The campground is well-known for its friendly staff and clean accommodations.

If you would rather sleep with a roof over your head, check out Barclay Bed & Breakfast. Transport yourself to an earlier time as you enjoy Barclay’s famous home-cooked breakfasts in a beautiful Victorian dining room. The clean and spacious rooms offer fascinating historical decorations with modern-day comforts. But avoid planning your visit around Groundhog’s Day; the B & B is packed during this time.

Little Mahoning Creek might not be the most talked about fishery, but it is still worth a visit if you are in the area. Enjoy!
