Blue-green algae at Pond in the River
Pond in the River is a pond in Oxford County, Maine covering about 0.7 sq mi, the 250th-largest of the 319 lakes SwimZone monitors in Maine. Satellite imagery detected no blue-green algae bloom as of July 21, 2026.
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.
