Beaver Creek begins in a wetland in West Abington Township, Lackawanna County. It flows southwest for a few tenths of a mile, receiving a very short unnamed tributary from the along the way, and passes through a lake before turning northwest.

The elevation near the mouth of Beaver Creek is above sea level. The elevation of the creek's source is between above sea level.
The surficial geology along the lower reaches of Beaver Creek mainly consists of alluvium, although Wisconsinan Till also occurs in the area. There are also a few small patches of Wisconsinan Outwash and alluvial fan. Further upstream, alluvium and Wisconsinan Till are also prevalent. However, there is also a patch of Wisconsinan Ice-Contact Stratified Drift, another patch of Wisconsinan Bouldery Till, and a few patches of wetlands and peat bogs.
The watershed of Beaver Creek has an area of . The mouth of the creek is in the United States Geological Survey quadrangle of Ransom. However, its source is in the quadrangle of Factoryville.
