St. Sebastian River

The Saint Sebastian River is a river in the U.S. state of Florida, a tributary of the Indian River west and north of the city of Sebastian.

Dredging
Dredging took place from 2006 through 2009, costing $18 million and removing 2000000 ft3 of muck from the bottom of the St. Sebastian River. The muck consisted of silt, clay, sand, shell and organic material, which consumed oxygen and threatened the life of aquatic species.
