Rock formations made of sandstone are in its watershed and rock containing carbonate minerals is at its headwaters.

Roughly seven eighths of the watershed of North Branch Buffalo Creek is on forested land, but agricultural land such as row crops and pastures occurs, as do impervious surfaces. The creek was historically used as water power for a number of mills and logging and agriculture have also been historically done in its watershed. It passes through a water supply reservoir known as the Mifflinburg Reservoir. A number of bridges have also been constructed across it.
