Description of mitigation measures/dates used: Deflectors, Glynn Banks (ERDC) on board (6/9-6/13) to provide expertise to avoid turtle takes, no dredging between midnight & dawn (6/9-6/13), began dredging with 1 dragarm on down river side of dredge (6/7-6/13)

Other Remarks: This project experienced difficulties in dragarm use due to rapidly changing sea currents. Tropical storm system may have pushed a number of turtles into the area, thus making them vulnerable to dredging operations. Several sea turtles were sighted: CC (subadult 6/9, 6/12, 2 on 4/29), UNK (juv 6/9, 2 on 5/15, 3 on 5/23). Several sharks including hammerheads were also sighted from the dredge. An old turtle bone was found on 5/8 and not considered a take by the dredge.
