Every summer, more than 200,000 people visit Lake Travis to boat, swim and get some sun. But longtime Austin resident Robert Baumgardner is more interested in the geography of the lake than recreation. Specifically, he's interested in the Sometimes Islands.

Over the past few days we've been hearing a lot about the Highland Lakes and the system of dams in the area. As all of that water makes its way down the Colorado River, we thought this would be a good time to get an explanation of exactly how that system works.

So we asked KUT's Mose Buchele.

Update: The LCRA now says it will not open eight floodgates on Thursday, Oct. 18, but may in the coming days. 

It’s never happened before, but the Lower Colorado River Authority will likely open eight floodgates on the Mansfield Dam above Lake Austin by noon Thursday.

So, what can you expect if you live in Austin?
