Last Dam

Around Austin-Sunrise at Austin's last dam, the Longhorn Dam. With three gates open, what is typically a meandering creek is rapidly flowing. The Longhorn Dam, just East of I35 in Downtown Austin, is 15.6 miles in a straight-line from what is the first dam in Austin, the Mansfield Dam. Wednesday July 22nd 2026, 07:12.

The left gate fully open creates rapid flow below. Two middle gates are partially open as well.
