A waterway ban that has been in place in Austin for nearly a month will be lifted at noon on Friday, the Austin Fire Department said in a statement.

Lake Austin, Lady Bird Lake and the Colorado River downstream of Longhorn Dam will reopen for commercial and recreational use.

The city had closed the waterways since Oct. 16 after heavy rain and historic flooding on the Highland Lakes made conditions unsafe.

The Lower Colorado River Authority, which manages the Highland Lakes upstream from Austin, said lakes Marble Falls and LBJ in the Hill Country will remain closed until at least next week because of swift water flow and hazardous debris.

Lake Marble Falls will not reopen until at least Monday, and Lake LBJ will not open until at least Friday, the agency said.

Property owners who live along the lakes and whose possessions were damaged in recent flooding will be allowed on the closed lakes for the limited purpose of recovering or securing damaged property, the LCRA said.

"Boating on the lakes remains dangerous, and time on the lakes recovering property should be minimized. Submerged hazards may be difficult to see, especially at night," the agency said in a statement Friday.

Lakes Travis, Buchanan and Inks have all be reopened to the public.

The LCRA ceased flood control operations this week following last month's storms. As of Wednesday, they had closed all the open floodgates at dams along the lakes.

However, heavy rains overnight Thursday into Friday prompted the agency to partially open a single floodgate at Bastrop Dam, which forms Lake Bastrop, to release runoff from the storms.

The lake recorded 3.17 inches of rain in the past 12 hours, according to LCRA rain gauges.
