(Lake Park)—The Cooperative Lakes Area Monitoring Project or CLAMP is warning residents about high levels of algal toxin in Silver Lake in Dickinson County.

Screening tests were conducted Tuesday for the algal toxin microcystin suggest elevated levels above what are considered safe for recreation. According to a Facebook post, as a screening test, it is not as accurate as a laboratory analysis, but people should use caution when recreating in Silver Lake.

Pets, children and the elderly are most susceptible to the algal toxin. Primary exposure is through ingestion. Rinse pets with clean drinking water if they come into contact with the water.
