North Jersey Lake’s Contamination Prompts Warning From Officials

WARREN COUNTY, NJ — A lake in Warren County is under a harmful algal bloom advisory, and experts are warning residents.

On March 17, a test was conducted in the waters of Liberty Township's Mountain Lake. Results have revealed that an algal bloom poses a "moderate health risk" to the public.

NJ Fish and Wildlife advises against humans or pets swimming or wading in the waters at this time. Residents should also avoid drinking the water or eating any fish caught in the lake.

Catch-and-release fishing, as well as boating, is still okay, but experts say residents should use extra caution, especially when kayaking or canoeing.

Harmful algal blooms occur when colonies of algae "grow out of control and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds," according to the National Oceanic and Atmospheric Administration.

The toxic bacteria detected in Mountain Lake are primarily "Phormidium," a species of cyanobacteria.

Consumption or prolonged contact with Phormidium can cause vomiting, diarrhea, tremors, paralysis, skin irritation, and potentially fatal consequences, according to the U.S. Environmental Protection Agency.
