Wiconisco Creek

Wiconisco Creek is a tributary of the Susquehanna River in Schuylkill and Dauphin counties, Pennsylvania, in the United States. It is approximately long.
Course
Wiconisco Creek begins on a bend on a mountain in Porter Township, Schuylkill County. It flows in the general direction of west-southwest for several miles between two mountains, Big Lick Mountain, which is north of the creek and Stony Mountain, which is south of the creek. The creek passes near Tower City, where the southern border of its valley is defined by Berry Mountain, and shortly afterwards leaves Schuylkill County.
Upon leaving Schuylkill County, Wiconisco Creek enters Williams Township, Dauphin County. In this township, the creek continues in a westward direction, crossing U.S. Route 209 and passing Williamstown. Further on, the creek enters Wiconisco Township, where it passes by the community of Lykens. Here, it receives the tributary Bear Creek and then the tributary Rattling Creek. Wiconisco Creek then leaves Wiconisco Township and enters Washington Township, where it picks up the tributaries Big Run and Canoe Gap Run. The creek then reaches the end of its valley and turns abruptly north, crossing U.S. Route 209 again. It briefly enters Lykens Township before starting to meander southwest back into Washington Township. Here, the creek crosses Pennsylvania Route 225 and continues meandering in the same direction. It crosses U.S. Route 209 again and enters Upper Paxton Township, where it begins to meander parallel to Berry Mountain. After a while, the creek stops meandering, but continues west, receiving the tributary Little Wiconisco Creek. The creek then reaches its confluence with the Susquehanna River between Lenkerville and Millersburg.
Wiconisco Creek reaches its confluence with the Susquehanna River upstream of its mouth.

The channel of Wiconisco Creek is tortuous. The creek flows through rock formations made of sandstone and shale. Deposits of anthracite occur in the watershed. The main rock formation in the watershed is the Mauch Chunk Formation. Other rock formations include the Duncannon Member of the Catskill Formation, the Llewellyn Formation, the Pocono Formation, the Pottsville Formation, and the Spechty Kopf Formation.
The Pocono Formation occurs in the southern part of the Wiconisco Creek watershed and also on the northwestern edge. The Llewellyn Formation and the Pottsville Group occur in the northeastern part of the watershed. The Pottsville Group is also found in the watershed's southeastern portion. The Spechty Kopf Formation and the Duncannon Member of the Catskill Formation occur in small areas in its southernmost portion. The rest of the watershed is on the Mauch Chunk Formation.
The Hazleton-Dekalb-Lehew soil association occurs in the southern, northeastern, and northwestern parts of the Wiconisco Creek watershed. A minute area near the mouth of the creek is occupied by soil of the Duncannon-Urban-Land-Chavies association. The rest of the watershed is occupied by the Leck Kill-Minersville-Calvin soil association.
