DIY Guide to Fly Fishing Codorus Creek in South-Central Pennsylvania

Why would anybody in their right mind visit a Codorus Creek, which has been known as “Inky Stinky” by nearby residents for decades?

A lot can change in twenty years. Codorus Creek was once well known for its signature pungent scent, but through a combination of lawsuit settlements and cleanup initiatives, the odor has all but disappeared.

Additionally, the water quality has improved and the insect population is bouncing back.

So what does this mean for the trout?

Surprisingly, Codorus Creek is now teeming with brown and rainbow trout. 

Codorus Creek has come a long way from what it once was. See for yourself!

Fly fishing Codorus Creek

Codorus Creek is a 42.4 mile long tributary of the Susquehanna River in York County, Pennsylvania. The headwaters are located in Maryland, and the creek is formed by the confluence of the south and west branches.

The East Branch is stocked and follows Park Road. But the West Branch is where things get interesting!

The tailwater section of the West Branch has the largest brown trout in the creek. It is around twenty feet wide and has plenty of weed growth, which might make you feel like you are in a spring creek.

This section also has shallow pools and riffles. But this section can also prove quite a challenge, as the overhanging branches make it difficult to cast.

Currently, plans are underway for a Codorus Creek water trail. Additionally, the Codorus Creek Watershed Association is working on preserving and restoring other local tributaries. One thing is for sure: Codorus Creek just keeps getting better and better!

Best Spots to Fish Codorus Creek

Codorus Creek is easily accessible from Codorus State Park. Codorus Creek runs along a CSX rail line and parts of Porters Road, Hayrick Road and Thomas Drive. You’ll be able to see small yellow signs as you approach indicating where the fishing areas are.

Fly fishermen have their choice between the freestone section or the West Branch. The East Branch is mostly a put-and-take stream. The West Branch is below Lake Marberg and was originally stocked. However, recently the state reclassified this section as a Class A Wild Trout Stream.

You’ll want to be careful with your footing at Codorus Creek. The creek is wadable but the water is cold even in the summer months, so you might want to don heavy socks under your waders.

The stream’s muddy bottom varies from hard to soft, depending on which section you are in. Since this creek also has a decent population of crustaceans and poison ivy,  you’ll definitely want to watch your step!

Best Time to Fish Codorus Creek

The season for Codorus Creek is the standard Pennsylvania trout season. The springtime is best, due to the hatches.

Although the insect population is improving from what it once was, the hatches are still sparser than you would normally find in a Pennsylvania creek. But fall is also a great time to visit, as you’ll find larger brown trout during this time.

You can also visit in the summer, but you’ll want to stick to the tailwater sections during the hotter summer months as the water is cooler there.
