No changes for Hamilton Pool despite drowning

HOUSTON Cho's family wants the potential dangers of Hamilton Pool outside Austin more clearly marked, including warnings about a steep drop off underwater.

"I hope that they have some sort of draw the line floating device beyond that point it goes down deeply so that people can make decisions and this kind of tragedy will not happen again," said Peter's father, Don Cho.

Travis County says it has signs posted at the location indicating no life guard on duty, and that people swim at their own risk.

We checked with Texas Parks and Wildlife. They say Cho's drowning was the first at Hamilton Pool in at least five years. Statewide in 2009, 128 people died in Texas lakes and rivers, and 36 of those deaths were boat-related. So far this year, there have been nine deaths.
