Kellum Creek is a tributary of Roaring Brook in Lackawanna County, Pennsylvania, in the United States.

The surficial geology in the area consists of alluvium, bedrock, peat bogs, wetlands, Boulder Colluvium, and Wisconsinan Till.

It then turns northwest for a short distance before reaching its confluence with Roaring Brook at the southern tip of the Elmhurst Reservoir.

However, they opened the creek and many others in the area to the public in 2002 by leasing the surrounding land to the Pennsylvania Fish and Boat Commission for $1 per year.

[9] A trail crossing Kellum Creek on its path from Pennsylvania American Water lands in Roaring Brook Township to a location near the sewer plant in Mosvow in the North Pocono region has been planned.
