The water is at historically low levels, and the last public boat ramp on Lake Travis could close at any time.

Lake Travis is fading away at a foot and a half per week. The "sometimes islands" by Mansfield Dam now look like more of a peninsula. Nearby is the last remaining public boat ramp that could go at any time.

Boaters Robbie Gleason and Caroline Hogan put their boat in within less than a half a foot of the ramp being closed.

"I was pretty surprised. I didn't think it would drop that quick. [It’s] really low. You’ve really got to pay attention to where you’re going,” Gleason said.

"The smaller boats and the shorter trailers aren't really a concern to the people operating the park right now. It's those larger boats and longer trailers that may have problems in the next week,” LCRA Spokesperson Krista Umscheid-Ramirez said.

Not everyone is willing to chance it.

"Last year we'd come out on the weekdays and it would be way more crowded but now there's only a couple people out,” Hogan said.

Lake Austin seems to be taking on some of the Lake Travis traffic.

“It's not very fun because you have less areas to where you can boat and there are more islands popping up and it's harder to see and gives you less water to work with than when you are here,” Austinite Alaine Comsudi said.

If the Mansfield ramp is closed, other lakes may get even busier because not all boaters are willing to pay for a private ramp.

“If anything else go to LBJ since it's a constant level,” Gleason said.

There is one plus. If the lake gets to 635 feet, Travis County parks crews will begin pouring cement. They plan to add onto the ramps at Mansfield Dam, Sandy Creek and possibly Pace Bend. Maybe with a few more feet of pavement, the next drought won't ruin the summer for any boaters.

Anything under 640 feet and the ramp will be closed. For the most current lake levels click on http://www.lcra.org/.
