How this read is built

West Solomon Lake is a lake in Kandiyohi County, Minnesota. EPA's CyAN satellite estimated a possible blue-green algae bloom here (August 19, 2026); this is a satellite estimate, not a water sample or an official advisory.

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.

Over 7 summers of EPA CyAN satellite imagery since 2020, West Solomon Lake has shown a satellite-estimated bloom-level signal in 7 of them, most recently in July 2026. It shows a bloom-level signal most summers. Its highest satellite estimate was about 2,700,000 cells/mL in July 2021. These are satellite estimates, not water samples or posted advisories; check your state or county health department for official status.

It is currently peak season for blue-green algae, when warm, calm water lets blooms form fastest. This lake has bloomed in most monitored summers (7 of 7), historically peaking around July. Early summer, before the water fully warms, has generally been the safer window here; check the current read before you go either way.
