We have recently had closings of some nearby Finger Lakes to all types of recreational use because of HABs and their related microcystin toxins. Upstream of Lake Ontario, western Lake Erie is suffering from a major HAB outbreak that has caused cities (e.g.: Toledo) to warn residents that they should not consume, cook or even bathe with water from the public water system. Basically they told the public not to use public water, period. Levels of toxins exceeded the World Health Organization’s (WHO) drinking water standard of one (1) part per billion (ppb). Toxin contaminated water cannot be made safe by boiling, chlorination or filtration.
Sodus Bay has had essentially no HAB outbreaks this year and toxicity levels, so far, are un-detectable at <0.1 ppb. The following information is preemptory and an attempt to inform you before the need to ask questions arises. One can safely assume that most guidelines for dogs are applicable to humans.
