Blue-green algae at Sunshine Cove/Yankee Cove
Sunshine Cove/Yankee Cove is a lake in Juneau County, Alaska. Blue-green algae are not currently monitored at this water.
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.
