I’ve heard for years about what I thought was a mythical creature - an eel that lives in Barton Springs. Turns out the eel is real, and was spotted as recently as a month ago by the ladder near the diving board.

That from Karen Kocher, producer of an interactive documentary being created about the springs.

You can catch a free screening of several of the short videos that will make up Kocher’s project at 8:30 p.m. tonight on the patio at the Beverly S. Sheffield Education Center, near the main entrance of Barton Springs. (No word yet on whether the eel makes an appearance.)

When complete, the documentary will be made up of several dozen videos about the history, science, culture and spiritual practices at Barton Springs. If you strung all that video together, Kocher says, it would run nearly twice as long as a feature film. Instead, the documentary will be made up of several dozen videos on a website that collectively tell the story of the springs. A high-resolution version of the project will be installed as part of a permanent exhibit at the Barton Springs Education Center.

If you plan to attend the screening, bring a chair or blanket to sit on. Afterward, jump in the pool and howl at the full moon - it’s an Austin tradition.
