DENVER -- There's a big mess at City Park where a lake is being overtaken by thick, green, slimy algae.

The city is trying to put together a plan to clean up the mess, but it's causing concern for waterfowl and water lovers alike.

The city's plans include bringing in vacuum trucks to suck the algae from the surface of the water. The water is also going to be chemically treated with copper sulfate added every two weeks.

Workers are going to try to skim as much algae from the top of the water as possible. The city said the hot weather has made the algae worse even though it's part of the normal lake ecosystem.

In the meantime, park rangers are taking time to talk to people and educate them about the algae growth, letting them know it's not dangerous.
