From KRDO (Kolby Crossley):
The City of Colorado Springs has finally reopened Prospect Lake after elevated levels of a microcystin toxin, or blue-green algae, prompted a 12-week closure…
So after three months, what exactly brought the levels down?
“Main reason is we’ve gotten the colder temperatures,” said Rodriguez. “The lower overnight lows and during the day the highs haven’t been as high so it’s really pushed that organism to stop growing.”

Now the question is: What will the city do to try to prevent this from happening again?
They’ll be trying a new water maintenance program.
Rodriquez said the maintenance will include several products that are “more food-safe, animal-safe, people-safe so that people recreating aren’t going to be exposed to anything that’s hazardous to them but it’s also going to keep our nutrient level in check and in line.”
Rodriguez also said that they are currently working on a protocol for when it comes to testing the water in the future.
