The “lake” is surrounded by giant man-made embankments on all sides, surrounded by an additional  set of embankments, with gates to let the water out. There is no dam per se, because there is ~200 km of this man-made 10-20m tall earthen embankment (levee) around the entire river system - it is part of that. 

this is still a dam for me?
