^ Lake Charles was always sort of foul. Granted, not as foul as it is at present, but the water has always smelled bad, it's always been scummy and it's alway been a mosquito hatchery, at least since I started visiting the park in the early '80s. Remember, there used to be a ride called Diamond Falls that was actually in Lake Charles, and I was regularly drenched with that terrible water.
Two of the reasons that LC is so nasty is because it's shallow and because it's drained all the time (or at least it used to be), so it's never been allowed to develop into anything more than a big puddle. I believe that deepening it and turning it into a real ecosystem and habitat would do a lot to clean it up. Stocking it with certain fish and wildlife would reduce the mosquitos as well.
Ugh! I can't seem to find the discussion I once read about the historical depth of Lake Charles. I believe that the discussion was on this forum, but I may be mistaken.
There was once a dive show in the lake, so the water had to have been somewhat deeper than the 3 feet it is today, at least in the spot where that show took place. There was also a water ski show, but you can water ski in fairly shallow waters if you're careful.
There was also that enormous fountain circulating the water. Since Anaconda only hangs around the outskirts of the "lake," perhaps they could add a fountain to the center of it. You know, maybe to cut back on mosquitos a bit.
