Ah the tides. What are the tides on the lake. I did a search and found nothing. Nobody has seemed to have written about the tides in the lake on the net. I am not done yet either.
There's a dam between the lake and the Gulf. Gulf salty, lake not. The lake is normally controlled at 1 foot above sea level.
There are no significant tides on a lake, the body of water involved is too small. Lake Michigan (300 X 90 miles and 900 feet deep) has only a 1 inch tide. I'm sure Lake Ponchartrain's "tide" is less than .001 inches.
