Mark Parisi, an assistant manager for Wheel Fun Rentals, works on repairing foot paddle boats on Ferril Lake near the Boat House at City Park on June 30, 2016 in Denver, Colorado. Denver Parks and Recreation is trying to take care of a huge algal bloom that has taken over the lake and shut down the boating on the lake. The department is using an algaecide that they are sprinkling by hand into the water as well as rakes to try to pull the long algae out of the water.
