Lake Pontchartrain is a generally oval-shaped lake whose south shore is metropolitan New Orleans, LA.

It is about 24 miles at most from north to south, which is the approximate length of the Causeway that crosses it. It is about 40 miles east-to-west, yielding a total area of about 630 square miles.
