Algae, if left unchecked can kill nearly all life in a pond or lake, make it difficult to use the lake for expected recreational purposes, and can also be smelly and unsightly. For many years, the Park District battled the algae that grows year round in the Park District’s retention ponds by contracting a private company to apply chemicals to ponds and lakes affected by algae growth. The chemical application, though relatively expensive, has been somewhat effective in most cases. In 2003, the Park Board approved an eco-friendly plan to install above water (fountains) and/or below water (bubblers), depending on the square footage and depth of the lake/pond aerators, in each of the District’s retention ponds over a period of years.
The first aerator was installed in Willow Lake in Deerpath Park in late fall 2003 and activated in spring of 2004. A second aerator in the west detention pond at Grosse Pointe Park was installed and activated in the summer of 2004. Three aerators were added to Little Bear Lake in 2007. Over the next few years, aerators are scheduled to be added to other Park District lakes, based on need.
In 2018, a set of underwater bubbler aerators were installed at Grosse Pointe to compliment the fountain. The underwater bubbler aerators will remain operable year around to increase the amount of dissolved oxygen in the water.
In 2019, the underwater bubbler aerators at Deerpath were replaced. One set is on the south end of the pond, complimenting the fountains. The other set is on the north end of the pond. Both sets of underwater bubbler aerators will remain operable year around to increase the amount of dissolved oxygen in the water.
After a reasonable test period, it appears the District was successful in meeting the primary goal of eliminating algae growth. The addition of the underwater bubbler aerators will increase dissolved oxygen into water. This will increase the chances for aquatic life to thrive.
Fountains operate during daylight into early evening hours April through November. Underwater bubbler aerators will operate 24 hours and day, 365 days a year.
