Water hyacinth has been the scourge of the Delta in recent years, but by this summer it could be providing the power to city lights. A pilot project is in the works to harvest it for biogas. Port of Stockton Environmental Manager Jeff Wingfield says the port is proposing a pilot project to harvest the
Heron Lake in far southwestern Minnesota was once considered one of North America’s most productive waterfowl lakes and in an effort return the lake into a productive waterfowl rest stop, the DNR has once again revamped their management plant. The DNR will systematically be adding predatory fish to sharpen the attack against the destructive carp,
Nyamitanga Division Chairperson Moses Karanzi Kajubi says the move to manually remove the water weed should be supported instead of being criticized. He says that they intend to do the cleaning of the river at least once a month, by pulling the water weed out of the water and cut it into pieces so that
The Department of Natural Resources has completed a Strategic Analysis of Aquatic Plant Management (APM) in Wisconsin, summarizing current information on APM and potential management alternatives. The Strategic Analysis report [PDF] will help inform decision-makers and the public about this topic and aid in the development of future APM policy. While aquatic plants are a
A new study maps the potential of wetlands – an ecosystem flooded with water and supporting a vegetation of aquatic plants – to improve water quality. Through the study, the researchers claim that regrowing wetlands can act as a key strategy for improving water that is laden with contaminants like nitrate. Nitrates reach groundwater, rivers,
As many Americans plan trips to lakes and river this Labor Day Weekend, experts are sending out a warning to watch out for toxic algae blooms. Researchers identified 318 bodies away in the US that have been infected by the microscopic organism called cyanobacteria. Approximately 86 percent of the outbreaks were in recreational areas, but
A highly invasive aquatic weed has been discovered in a number of ponds in the Animas Valley in Colorado, putting the heat on to eradicate it before it enters the Animas River and, potentially, Lake Nighthorse. The invasive weed aggressively outgrows and outcompetes native aquatic plants. It can then clog irrigation systems and ponds, and
Bow fishing, as opposed to an environmental fish kill, is behind the recent culling of hundreds of carp in Paddock Lake, Wisconsin. Flooding led to a rush of runoff into the lake, which, in turn, reduced oxygen levels. This can lead to a natural fish kill, and some carp perished as a result. However, village
In southwest Minnesota, the Okabena-Ocheda Watershed District is tagging and tracking carp in an effort to find out where they congregate in the winter. The data is hoped to reveal the potential for a wintertime seining event. Lake Okabena has two to three times more carp than a healthy lake should have. It’s been determined
