Officials determined that that fish died from a low dissolved oxygen level in the water, basically suffocating the fish. The low dissolved
Winterkill occurs when fish suffocate due to a lack of dissolved oxygen in the water and is the most common type of fish kill. Dissolved oxygen is required by fish and almost all other forms of life living in water bodies. Even bacteria living on lake bottoms require dissolved oxygen to survive. Low oxygen levels
A heat wave combined with a chemical treatment for weeds proved to be deadly to some fish in Bon Aire Lake, according to the executive director of Merrillville Stormwater Utility. Matt Lake said about 100 fish died recently in an isolated incident in the 21-acre lake when the heat index rose to 110 degrees the
About 5,000 fish have died because of algaecides applied to Hartwell Lake in an effort to improve the region’s drinking water. The South Carolina Department of Natural Resources and the state’s public-health agency are investigating the fish kill, which affects the area around the Anderson Joint Regional Water System’s intake on the lake. 160 acres
An outbreak of toxic algae has killed almost all fish at Lake Mission Viejo, a world-class bass fishery in California.

Suburban Chicago official says hundreds of fish died in the community’s lake when oxygen levels plummeted after an herbicide was applied to combat aquatic plants. About 400 fish, including largemouth bass, died last week in Libertyville Illinois’s Butler Lake soon after a company applied a chemical that’s designed to control invasive weeds, including the lake’s
