The rain is ending, but Austin says it’s still too dangerous to get on the water

Austin Fire Chief Joel G. Baker on Friday issued a temporary ban on recreational, commercial and navigational use of Lake Austin, Lady Bird Lake and the Colorado River downstream of Longhorn Dam. The order took effect immediately and remains in place until 5 p.m. Tuesday.

According to the city, heavy rainfall that began earlier this week prompted floodgate operations at Mansfield Dam and Tom Miller Dam, creating high, fast-moving water and sending debris downstream. Officials said those conditions have made the waterways unsafe for boating and other recreational activities.

The order also warns that people can be cited for violating the ban or attempting to cross barricaded low-water crossings. It also says watercraft operating illegally within the restricted areas may be impounded.

The restrictions come as floodwaters continue moving through rivers and creeks across South Central Texas, even though the threat of additional heavy rainfall has diminished. In its Saturday forecast discussion, the National Weather Service said elevated water levels will persist in several river basins into early next week and urged people to avoid flooded areas and never drive through flooded roads.

Even after rain stops, flooding may continue to cause impacts.

Monitor road conditions and pay attention to forecasts especially if you live near waterways or downstream.

The weather service also warned Saturday that creeks, rivers and standing water remain hazardous even after floodwaters begin to recede. In a public safety message shared on social media, it said hidden dangers can include displaced wildlife, stinging insects, live electrical wires, bacteria, toxic chemicals, raw sewage and submerged debris.

While dry weather is expected to continue through much of next week, the NWS said hot July temperatures and humidity will return as floodwaters slowly recede.
