Staying vigilant: Harmful algal blooms remain in Utah Lake, Deer Creek as summer turns to fall

Harmful algal blooms remain active across Utah Valley as summer recreation fades and hunting season begins, according to the Utah Department of Environmental Quality. Most of Utah Lake is under an orange advisory, advising people not to swim while allowing boating. Lindon Marina has a red advisory, urging boaters to avoid algae areas. Deer Creek Reservoir in Wasatch County received warning advisories this month. East Wallsburg Bay and the South Basin boat ramp are yellow, while Rainbow Bay and Island Park Marina are orange, again directing people to avoid swimming. Fishing is allowed, but officials suggest discarding skin and guts. The state plans to stop monitoring in October, though risk persists later. Waterfowl hunters are urged to keep dogs away.
