Presa El Pedregal is up highway 80 near Lazaro Cardenas and was built to better control flooding downstream, mainly in Melaque. When I was there a few years ago I don't remember the lake being that large. The water level may have been a lot lower but it sounds like that may not all be water. Last summer local residents reminded the Municipality that the lake had never been dredged. I hope this is not another "build it and abandon it" project so common in Mexico.
