What Am I Missing?

East Baton Rouge Parish is moving forward with plans to protect downtown Baton Rouge from the rising Mississippi River. The Department of Public Works says they’ve purchased miles of boom from the Kenner, La company, Tiger Dam. They will begin installing the boom from Hollywood Casino to near LSU on Wednesday.
These are the same bright orange tubes used to keep oil away from barrier islands in the Gulf of Mexico after the BP oil spill. This time, the boom will be filled with river water, stacked and anchored to the levee, adding up to 18 inches of height to the levee system.
The boom will remain in place until the Mississippi River levels recede.
Even filling them with water, shouldn't they still have some bouyancy?

You just answered your own question

did you miss the part where he said they will be anchored to the levee??

But won't the anchors just displace more water, thereby raising the water level!?!?!

I can see it if they are strapping them down securely, but at the same time isn't the digging/drilling into the levee that would be required for that a bad thing?

i think this is just that little extra security measure b/c they can do it.
the buoyancy wouldnt be an issue unless a good amount of water could get under them. they will be extremely heavy and would need at least a foot of water under them to create lift....

Makes sense. Thanks!

The rubber is denser and heavier than water. And that is a lot of rubber. So it should have an overall specific gravity higher than the water.
