Environmental advocates say springtime harbor dredging in Georgia would harm nesting loggerhead sea turtles. ATLANTA – Environmental advocates opposing a plan to dredge coastal Georgia shipping channels starting this month have won a court victory. U.S. District Judge Stan Baker granted a preliminary injunction Thursday blocking the U.S. Army Corps of Engineers from dredging activity in Brunswick Harbor that had been due to begin May 28. In a lawsuit against the Corps filed on behalf of the group One Hundred Miles, the Southern Environmental Law Center argued dredging this time of year would harm endangered loggerhead sea turtles. The Corps historically has limited dredging to the winter months, when the turtles are not nesting.
