Bucks Creek is in the Sulphur Springs System. The system consists of Cockle Cove Creek, Bucks Creek, and Sulphur Springs. Cockle Cove is a salt marsh with a central tidal creek that drains almost completely at low tide. Sulfur Springs is a shallow embayment at the head of Bucks Creek that is transitioning to a salt marsh. The entire system is undergoing ecological change resulting from the constant physical change at the mouth of Bucks Creek.
