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
Michigan anglers are fed up with the way some area lake associations have amped up their aquatic plant treatments in recent years. The annual dump of herbicides has destroyed a lot of fish habitat in recent years. It doesn’t matter whether you fish for panfish, bass, pike or walleye; excessive treatments have negative effects. Plants
An outbreak of toxic algae has killed almost all fish at Lake Mission Viejo, a world-class bass fishery in California. An estimated 10,000-plus bass, catfish, sunfish and blue gill have died in the past few months at the man-made recreational lake, said Kevin Frabotta, general manager of the Lake Mission Viejo Association, the homeowners association
Commercial fishermen and fish fertilizer suppliers are struggling to keep up with a demand for carp as people spend more time gardening and growing their own food during the pandemic. The impacts of carp include a reduction in water quality, riverbank damage, and potential contribution to algae blooms which comes at the expense of native
Water suppliers along the drought-stricken Colorado River hope to tackle another tricky issue after the U.S. Bureau of Reclamation installs a new leader: salty water. The river provides water for 40 million people from Colorado to California, and helps irrigate 5.5 million acres of farm and ranchland in the U.S. But all that water also
The water of Hamilton Harbour in Ontario, Canada, has been used and abused over the decades, as sewage water and industrial by-products have flowed into the port since the 1800s with devastating consequences for the harbor’s flora and fauna. Today, treated sewage water, which isn’t fully cleansed of algae-causing nutrients, is still released into the
Marine ecosystems suffer from nutrient pollution, as most of our waste tends to get dumped in the sea. This kind of pollution can become very deadly, as high levels of nutrients foster algal blooms which destroy water quality and deplete its oxygen — in short, they kill everything else around them. New research at the
Whether you visited Renner Reservoir for the first or 10th time this summer, you probably noticed a branchy, aquatic algae called chara covering the bottom of the reservoir. Compared to other aquatic plants, which are referred to as macrophytes, chara forms denser mats offering less habitat for fish and a less palatable meal for invertebrates.
LakeLine A publication of the North American Lake Management Society Fall 2000 Innovative Technologies for Lake Management Africas’ Lake Victoria is the second largest freshwater lake in the world. It is less than 260 feet at its deepest point. For nearly ten years a growing water hyacinth infestation has wreaked havoc on the neighboring countries.
