We have traveled 75 miles and passed through 3 locks today. The Ten-Tom now consists of broad lakes above the dams with narrow channels below. Our first eleven lock-throughs raised us from 0 to 330 feet above sea level. The 12th of the “dirty dozen” (Whitten Lock and Dam) will raise us another 85 feet! Since the dam has no spillways, there is no flow passing through the dam except for the small amount that occurs via lock-throughs. The water below and above the dam is extremely clear.
This will be our last “up” and soon we will then we will start to go down when we cross the divide of the Tombigbee and the Tennessee watersheds (The Tennessee is north flowing while the Ten-Tom and Tombigbee is South flowing.) At this point, 150 million cubic yards had to be dug out (1,300 feet wide and 175 feet deep) in order to connect the river to these two watersheds.
Following the Tennessee watershed, we will lose elevation all the way to the Ohio at which time we will then go up again.
We are staying at Grand Harbor Marina, www.gograndharbor.com, tonight and having dinner at Johnny's Pier.
