The Little Red River in Heber Springs rises 8′ per unit they run. There are two generators. If you’re below the dam at Dam Site Park, you’d better get out of the water pretty quickly when the horn sounds. Steps that you walked down 10 minutes ago will be submerged in a few more minutes.
So if you’re planning to wade fish the Little Red, you’re going to want to know about the generation schedule. Here’s the generating schedule (updated daily). Of course, like everything else in life, this is “subject to change,” but it’s better to know than not know.
