More Dam Facts
Even if the rain stops soon, river levels could stay high for weeks.

With the continuing rains and the already saturated soil meaning water levels continue to rise, the Lower Colorado River Authority is saying local river and lake levels could stay high for weeks. This means they'll have to keep opening floodgates across the Colorado dam system well into July.
The river is still below flood levels, although it has reached "bank full" status at several points, and the LCRA is balancing river and lake levels around the clock to keep it that way (even their press officers are working 'round the clock to keep people up to speed). To manage this, they're using Lake Travis as storage and managing the levels upstream by controlled floodgate usage at the Buchanan, Mansfield, Tom Miller, Wirtz and Starcke dams. The water dumping over the Inks Dam spillway, just for context, is now four to five feet high.
Recreational boating bans remain in effect on Inks Lake; lakes Travis, Marble Falls, LBJ, and Austin; Town Lake; and the Colorado River downstream of Longhorn Dam. However, check the LCRA site, since they'll be updating the bans daily. (And just before this was posted, the city of Austin further extended its watercraft ban. See press release under "continue reading.")
Area waterway restrictions continue into next week
City of Austin officials have extended the current boating ban for all of Lake Austin, Town Lake and the Colorado River below the Longhorn Dam through noon Tuesday, July 3.
The extended ban is necessary due to the Lower Colorado River Authority’s continuing operations at Mansfield Dam and Tom Miller Dam. Flood gates have been open all week, creating very swift, debris-filled waters and unsafe conditions.
Persons with interests along these waterways should contact the City of Austin Parks Police Headquarters at (512) 974-7707 during business hours to receive written authorization to secure or remove property in the Flood Ban Area. Proof of ownership or occupancy is required.
Watercraft illegally operated on waters in the Watercraft Ban Area is a Class C Misdemeanor, punishable by fines up to $500 and boats may be impounded. Crossing barricades put in place on roadways or boat ramps for public safety can result in a Class B Misdemeanor, punishable by jail time up to 180 days and fines up to $2000.
City officials urge residents to be safe during a flood. Most fatalities occur when people drive through flooded roads or walk near creeks or low-lying areas. Be aware that water can rise very quickly and avoid low-water crossings. At night it may be difficult to see water on the road. Never attempt to drive, swim or walk through water that is flowing in a roadway, ditch or storm drain. "Turn around, don’t drown!"
