Five people died in Central Texas floods in October, and then the rain kept coming for the next two months. Catastrophic flooding devastated the Hill Country, and statewide at least 180 Texans died because of the countless overflowing rivers and creeks.

When storms roll in, water rushes downhill fast, gaining speed and force as it moves — often with deadly results.

TEXSAR, an Austin-based nonprofit first responder organization, has deployed swiftwater teams, boats, drones and K9s to help search for missing people. It hopes to raise $100,000 to maintain its operation. Donations can be made online.
