Deprato Mounds (16 CO 37), also known as the Ferriday Mounds, is a multimound archaeological site located in Concordia Parish, Louisiana. The site shows occupation from the Troyville period to the Middle Coles Creek period (400 to 800 CE). The largest mound at the site has been radiocarbon and decorated pottery dated to about 600 CE. It was added to the NRHP on October 22, 1998 as NRIS number 98001258.
The site is a complex of five platform mounds and a central plaza area sitting on four acres of land to the east of the confluence of Black Bayou and Bayou Cocodrie. The mounds now appear smaller than they were in the past because extensive flooding since their construction has deposited 3 feet (0.91 m) of sediment over the base of the mounds and the plaza. The largest remaining mound, Mound C, has a base measuring 82 feet (25 m) by 66 feet (20 m) and is about 6 feet (1.8 m) in height. Mound D has been used as fill for a highway construction project. Mound E is now the location of a house. During excavations human remains were found in three of the mounds. The site has been purchased by The Archaeological Conservancy, a nonprofit organization that plans to protect the site from future degradation.
