Barton Springs Pool and the Barton Creek Greenbelt are closed Thursday because of swift water, debris and erosion on the trail after overnight storms dumped as much as 3 inches of rain in parts of the Austin metro area, the city's Parks and Recreation Department said.

City officials are asking that people obey signs and do not use the greenbelt until the Parks Department determines it is safe.

Barton Creek is also closed until further notice because of rapidly moving water, the city said.

"The Parks Department is closely monitoring the greenbelt, creek and pool conditions, and as soon as conditions improve, we will inform the public," city officials said in a statement.

Barton Springs Pool, Austin's iconic swimming hole, is closed for its weekly cleaning day, and the city said it will determine when to reopen it based on conditions.
