While we don’t test for blue-green algae in Lake Sixteen, the Oakland County Parks and Recreation Natural Resources Staff and our lake contractor monitors the water for visual signs of harmful algal blooms (the first step in detection). If any suspicious material such as mats, discoloration, foam, or scum are found, it would be immediately reported to the Michigan Department of Environment, Great Lakes and Energy for follow-up testing. Lake Sixteen is not a particularly shallow or nutrient rich lake, making it less susceptible to the formation of harmful algal blooms. No suspicious material has ever been found on Lake Sixteen. The Oakland County Parks and Recreation Natural Resources Staff does other testing on the lake and works with volunteers through the Michigan Clean Water Corps on testing the lake. The results from 2018 can be found here.
