Know & Report Golden Algae

Passport to Texas from Texas Parks and Wildlife and the Sport Fish and Wildlife Restoration Program

Small, relatively harmless, populations of golden algae exist in most freshwaters. Yet when conditions are right, as when temperatures cool, the population of this toxic organism may explode.

It could very well be that the cold knocks down the other competing algae so that then the golden algae has an advantage over them and blooms.

Dave Sager works with inland fisheries in the area of ecosystems and habitat assessment. He says golden tinged water with foam on the surface is a sign that a bloom is underway. Dead fish is another.

Initially, the fish that are in the shallows or at the surface of the water are impacted first. You’ll see the bait fish, the shad or minnows and shiners that will die first. And then later on as the bloom and the toxins spread through the water column you’ll see other fish like the sunfish, large mouth bass, striped bass and others starting to be affected.

Sager reminds freshwater anglers and boaters that they play an integral role as a kind of early warning system.

They can see when a fish kill event is taking place – see that the water is golden; there’s foaming on the water. And call in to let us know so that we can then go out and do an investigation.

You’ll find the number to call to report a golden alga bloom at passporttotexas.org.
