Wetzel Run

Wetzel Run is a tributary of Kern Run in Snyder County, Pennsylvania, in the United States. It is approximately 4.3 mi long and flows through Beaver Township.

Course
Wetzel Run begins on a large ridge in Beaver Township. It flows northwest for several tenths of a mile before turning north-northeast for several tenths of a mile, receiving an unnamed tributary from the right. It then turns north-northwest for a few tenths of a mile before turning northeast for several tenths of a mile, receiving another unnamed tributary from the right and reaching the bottom of the ridge. The stream then turns north for a few tenths of a mile before turning northwest. After several tenths of a mile, the stream turns west and then north-northwest, crossing US Route 522 and approaching Thomas Ridge. Here, the stream disappears from the surface and turns west for several tenths of a mile before reaching its confluence with Kern Run.

Wetzel Run joins Kern Run 1.10 mi upstream of its mouth.

History
Wetzel Run was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1191196.

A bridge carrying US Route 522 over Wetzel Run was built in 1927. The bridge was a relatively narrow, single-span concrete bridge with a length of 24 ft. Eventually, the bridge deteriorated to become functionally obsolete and was replaced in 2012 for $456,000. The new bridge had two 12 ft wide lanes and 8 ft wide shoulders and is a precast concrete box culvert bridge. The new bridge opened for traffic on August 27, 2012 and is predicted to last at least 50 years.

Biology
Wild trout naturally reproduce in Wetzel Run for 3.59 mi of its length.
