The creek is fed by several small tributaries and is dammed at several points. Seasonal trends show increased flow during spring thaw and precipitation events. Interestingly, the creek was the site of a Revolutionary War battle and George Washington’s troops crossed it during the Valley Forge encampment. The hydrology of Valley Creek is affected by land use changes and stormwater runoff from nearby residential and commercial areas.
