Starting at low tide on March 8, the water remaining in the chamber will be pumped out so the lower walls and floor are accessible.
The pumps for this operation are located underneath the Administration Building. If you peek in the basement windows, you may be able to see some of the plumbing for the pumps.
Barring unforeseen findings, the small lock is scheduled to re-open to boat traffic by March 20.
