Current schedule is 2006. It already has started. This is the first dredging effort.
Much more work remains to be completed.
The dredging work will not create any water quality problems. The new Normal Pool will be 3.2 feet lower than the existing Normal Pool of elevation 726.9, or elevation 723.7. Here's what that means in relation to what you would normally see. For instance, say the upper gage at Locks 3 Elizabeth was at 9.7 feet. Therefore, the new Normal Pool level will be 3.9 feet below the river level you see right now.
