The Little Schuylkill River was known as the Tamauguay Creek or River in the 18th and early to mid-19th centuries.[3] Its name is derived from the Lenape word for "beaver" (tëmakwe[4] or tamaqua) and also the Lenape method for using "hunter’s hints,"[5] which identified it as the "place of the beavers".
When European settlers arrived in the region, the Little Schuylkill River, a tributary of the Schuylkill River, came to be known as Little Schuylkill River with the name Schuylkill coming from the Dutch language word that translates as "hidden river".
