The new shift begins dredging the channel, bucket by bucket.


Crane empties its bucket into the dump scow.


The bucket is huge! It scoops up 8-10 yards of sand.

Dredging is to be completed in approximately 10 days. (Work began Sunday, June 22, 2003) The crane using its clamshell bucket will dredge a channel along the dock, removing material instead of moving the material as the Sandwick did.

A loaded dump scow holds about 1,200-1,400 cubic yards of material. During the operation, the scow will be loaded at different levels depending on the depth of the water. Approximately 50 seconds elapse from the time a scoop is taken, emptied into the scow and returned for the next scoop. In a perfect world, using the 8 yard bucket, it should take 2.5 hours to fill the scow to the 1,200 cubic yard level.

It takes 30-45 minutes for the scow to move out around the jetty, release it's load and return.
