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.
The locations of wetlands can vary widely from marshes and ponds, to edges of lakes and oceans, to low lying areas that flood often. In today’s world wetlands, like many other natural ecosystems, are threatened by human activity, global warming, and the changes both are bringing with them. These natural environments play a number of
As algal blooms flourish on the edges of the Great Lakes, lake management bodies look to cut down the flow of nutrients into the water that feeds the algae. But, as a recent report by the International Joint Commission explains, not all parts of the lakes suffer from too many nutrients — in fact, the
To clean up the pollution in Jordan Lake, North Carolina lawmakers have tried arguing. They’ve tried SolarBees. They’ve even tried ignoring the problem. All those tactics have failed. Now state officials are examining a potential chemical treatment for the lake — yet another experiment on a vital drinking water source for more than 350,000 people.
In August of 2018 starry stonewort, an aquatic invasive species was found in a lagoon of Geneva Lake and within a year it was found in Geneva Lake. Initially it was hoped that the isolated population in the lagoon could be eradicated by dredging before it got into the lake, but the attempts failed and
