I heard the stories but I found the truth when it totally dried up a couple years ago. Just look up the fire that occurred at that time during years of drought. That was a MYTH...THAT IT WAA BOTTOMLESS. IT HAS A BOTTOM AND THE DEPTH OF THE LAKE IS APPROXIMATELY 10 FEET.

It is so low now you can walk across it. About 3 feet at it's deepest point.

It's a state law, not a L.A. County law.<br /><br />Garry: As you probably know, Lost Lake isn't really a sag pond. It was formed when offset stream terraces created a closed depression that filled with water.<br /><br />This area is one of the places I like to take my students. After Lost Lake we go up Lone Pine Canyon to Wrightwood, where we discuss debris flows and actinolite. Then it's on to Big Pines, Jackson Lake, Pallet Creek and the Devil's Punchbowl.
