From 9News.com (Caitlin Hendee):

Boulder residents are advised to keep their children and animals out of Wonderland Lake in north Boulder and a similar warning was issued for Quincy Reservoir in Aurora.

Sloan’s Lake is the only body of water in Denver that has tested positive for the algae. Signs are posted there warning people not to swim or wade in the lake, though health officials said they haven’t heard of anyone getting sick from it.

Thunderbird Lake in southeast Boulder also has reports of blue-green algae. Swimming and wading are not allowed there.

Blue-green algae is a bacteria found in non-flowing freshwater that can be fatal to animals if ingested. The algae naturally occurs in aquatic ecosystems and can appear rapidly – especially during the summer with hot weather and in slow-moving water bodies, such as lakes, according to the Colorado Department of Public Health and Environment…

According to the Colorado Department of Public Health and Environment, harmful algae blooms often have the following characteristics:

  • May look like thick pea soup or spilled paint on the water’s surface.
  • Can create a thick mat of foam along the shoreline.
  • Usually are green or blue-green, although they can be brown, purple or white.
  • Sometimes are made up of small specks or blobs floating just at or below the water’s surface
  • Blue-Green algae bloom

    1. I’ve seen some mats of algae in several Nebraska lakes. I don’t know if it’s blue-green algae (maybe it all is), but the lakes look like Monet paintings, some complete with waterlilies.
