Officials are asking for your help to track blue-green algae in Lake Champlain.
Algae blooms can produce toxins that cause nausea, skin irritation and in severe circumstances death in dogs.
The Lake Champlain Committee uses visual monitoring with the help of volunteers. Dozens of locations are observed and reported around the lake on a weekly basis for 12 weeks. Volunteers are required to take one half hour each week and attend one training session.
"I believe we are the only monitoring program in the country that reports the absence of blooms as well as their presence. Last year, we had 468 reports and less than 6 percent of them saw algae. So sometimes there's a mistaken impression that the algae is always in the lake and everywhere in the lake, and we're trying to get a better handle on when they actually occur and where they actually occur," said Mike Winslow of the Lake Champlain Committee.
