Syracuse, N.Y. -- More than 80 water bodies in New York state have harmful algae blooms, the Department of Environmental Conservation reported today.

This week's total of 81 is the highest this year. September is the peak season for blooms, and the past week's hot, dry weather helps the algae thrive.

Seventeen of the water bodies are new on the list this week, include three Finger Lakes: Conesus, Owasco and Seneca. The DEC said other lakes might also have blooms that haven't been reported or confirmed yet.

Toxins produced by the blooms can kill dogs and sicken people. The DEC urges people to avoid algae blooms and especially to keep their dogs away.
