HERRIMAN, Utah (AP) - The popular Blackridge Reservoir in Herriman may be closed for weeks as officials determine if an algae bloom may be toxic.

The lake with white sand beaches was closed Thursday after four to five algae species were discovered turning the water green.

The algae can be seen on the surface of the water and on rocks along the northern edge of the reservoir.

City officials say it is likely due to a clogged aerator that has since been replaced and that the reservoir is being closed as a precaution, potentially for weeks until health risks are determined.

Toxicology lab results are expected next week.



A scheduled triathlon will move its swimming events on Saturday to the Sorensen Recreation Center in Herriman.
