Blue-green algae at Laurel River Lake
Laurel River Lake is a lake in Laurel County, Kentucky covering about 9.3 sq mi, the 7th-largest of the 11 lakes SwimZone monitors in Kentucky. Satellite imagery detected no blue-green algae bloom as of July 19, 2026. Larger, warmer waters like this can hold a bloom for weeks once nutrients and calm weather line up.
Blue-green algae (cyanobacteria) blooms are most common from midsummer into early fall, when the water is warm, calm, and rich in nutrients from runoff. They can produce toxins that make people sick and can be rapidly fatal to dogs, so skip water that looks green, scummy, or like spilled paint, and keep children and pets out of it.
