Maiden Creek is a 20.3-mile-long (32.7 km)tributary of the Schuylkill River in Berks County, Pennsylvania in the United States. The name "Maiden" is an English translation of the Native American word Ontelaunee.
Maiden Creek is formed by the confluence of Ontelaunee and Kistler creeks in the community of Kempton. The tributary Sacony Creek joins at the community of Virginville.
The creek was dammed in 1926 to form Lake Ontelaunee.
The creek joins the Schuylkill River northeast of the city of Reading, for which it serves as the main drinking water supply.
The Maiden Creek watershed covers approximately 216 square miles (560 km2) with more than 2,100 miles (3,400 km) of perennial streams, including Maiden/Ontelaunee Creek and ten named tributaries (Kistler Creek, Stony Run, Pine Creek, Furnace Creek, Mill Creek, Sacony Creek, Peters Creek, Baileys Creek, Willow Creek, Moselem Springs). The watershed is in the southeast portion of Pennsylvania, lying within the upper Schuylkill River Basin in northeastern Berks County and extreme western Lehigh County. Small portions of eastern Schuylkill County lie within the watershed at the ridgeline of Blue Mountain and in State Gamelands. Nineteen townships and five boroughs, or parts thereof, lie within the watershed. The boroughs of Kutztown, Fleetwood, Lenhartsville and Lyons, along with Greenwich, Maidencreek and Richmond townships lie entirely within the watershed. Nearly all of Albany, Lynn, Maxatawny and Windsor townships are within the watershed as well.
