Boardman River Dam Update: 9/12

First off, I’m happy to announce that we saw the entire family of Trumpeter Swans flying low over the pond and landing this morning before our Construction Team meeting.   Prior to this we had reports that the cygnets were exercising their wings but no one had actually seen them in flight until today.   It was obvious by a couple face plants that they still need to work on their landing technique!

As of Monday, Molon had dredged 53,810 cubic yards of material.   That number should surpass 55,000 by the end of the day today.  The Molon crew opened the new section of channel below the East Overlook to water today and hope to have water flowing through the remainder of the new channel by noon tomorrow.

After this, they will commence with the remaining 2.5 foot drawdown that can be obtained using the existing gates in the lower part of the power house.  This will help dry up the east delta area so Molon can begin shaping the floodplain along the banks of the new river channel while the crew working on the sheet pile finishes up the temporary drawdown structure.   It’s anticipated the temporary drawdown structure will take a couple of weeks to complete.  At that time Molon will proceed with the final drawdown of the pond.

The young swans should be strong fliers by then. Please check out the progress from the East Overlook in person if you have a chance.
