The flow of the creek is influenced by precipitation, snowmelt, and agricultural runoff. There are no notable tributaries or dams along the creek. During the winter months, flow is generally low, while spring and summer rains can cause significant flooding. Interestingly, the Big Creek has been a source of controversy as it runs through a coal mine that was accused of polluting the creek. The mine has since been shut down, but the impact on the creek's hydrology remains unknown.
