Rainbow trout caught on Big Spring Creek in Pennsylvania

DIY Guide to Fly Fishing Big Spring Creek in South-Central Pennsylvania

They don’t call it Big Spring Creek for nothing.

Big Spring Creek is the fifth largest spring in Pennsylvania, and is one of the world’s most productive limestone spring creeks.

Native brook trout and wild rainbows in the 5 to 10-pound range were once common here.

Fly fishing Big Spring Creek, however, is no easy task.

The water in Big Spring Creek is crystal clear, which makes this a beautiful but difficult fly fishing location.

If you are not afraid of a challenge, Big Spring Creek is a wonderful choice for the adventurous angler.

Big Spring Creek is a five mile long tributary of Conodoguinet Creek in Cumberland County, Pennsylvania. It emerges near U.S. Route 11, approximately eight miles northeast of Shippensburg, and feeds Conodoguinet Creek near Newville. The creek is fed by smaller streams, which helps keep the water temperature cool all year.

Big Spring Creek was once known nationwide as one of the best brook trout fishing streams in America. Unfortunately, the creek has lost some of its prestige. From 1972 to 2003, Big Spring Creek had its own state fish hatchery at the head of the stream. The effluences from this system took a toll on the native trout and insect population.

But all is not lost! You’ll still find a good population of large brook trout in the upper reaches. There are also plenty of rainbow and brown trout waiting to be caught - but only if you’re sneaky enough!

The crystal clear water in this stream makes it difficult to sneak up on the trout. You’ll want to use light leaders and tippets here. Accuracy is also key so you don’t accidentally spook the trout. The fish here can be picky eaters, so you’ll also want to ensure you have the right flies.
