"Right so its alot easier to plug the canal at the lake - it appears to be about 75' wide."

I have a good image here that says the canal is ~the size of the breech, 200' according to reports.

There is a photo above showing boththe breech and the mouth of the canal.

the canal is alot narrower than the breech - and duh - did it ever occur to put a lock on the mouth of the canal?
