Manage invasive and overgrown aquatic vegetation in lakes, rivers, and wetlands. Solutions include mechanical harvesting and safe plant control methods.
New summer, same problem. The weeds in Lake Hopatcong in New Jersey are back and, according to at least one aquatic and watershed management expert, are “some of the worst” in recent memory. Fred Lubnow, director of aquatics programs at Princeton Hydro, has been studying the lake for more than 20 years. He said in
Bioengineering is defined by the Michigan Department of Environmental Quality as “using a combination of native planting and natural, or biodegradable materials to provide shoreline protection.” It also is often referred to as softshore engineering or lakescaping. Many shorelines use seawalls. These are a hard surface, such as wood, metal or concrete, that is installed
Around 3,707 tonnes (4086 tons U.S.) of weeds have been cleared from the 910-acre Bellandur lake. In the past five days alone 737 tonnes (812 tons U.S.) have been removed by just two machines, according to an official release issued by the Bangalore Development Authority. The BDA is said to be using three weed harvesters
Invasive curlyleaf pondweed has been choking East Okoboji Lake, snarling boat propellers, burning up motors and shutting down swimming, tubing and other water sports in an area that depends on recreation. The weed’s invasion is driving heated debates about how to control it — from using mechanical removal to administering herbicides that raise concerns about
In the fight against weeds growing the airport’s pond used by floatplanes, the weeds came out on top in previous years. However, their new weapon; which isn’t new at all, but 20 years old, seems to be winning the war on weeds. Juneau, Alaska, airport manager, Dave Palmer said staff tried herbicide and various other
In response to a plan put together by Lake Pend Oreille Waterkeeper, council members decided to decline the Idaho State Department of Agriculture’s offer to apply herbicide treatments in areas of watermilfoil infestation. This option came at no cost to the city, but the idea of herbicides in the water made many residents cringe. After
In Stockton, California managers have been trying to keep the water hyacinth that washes in from the Delta under control with herbicide treatments. Unfortunately even after 15 applications, the hyacinth has extended beyond the level of control. Port officials say a state spraying program failed to control the hyacinth, so they contracted with a Bay
Hydrilla’s roots run deep in Florida. After a Gulf Coast aquarium dealer had the plant shipped from Sri Lanka in the early 1950s, the stringy nuisance has cost government agencies countless millions. Hydrilla grows up to two inches a day, clogging lakes, rivers and canals that flow to the Melbourne-Tillman (C-1) canal in Palm Bay.
After 20,000 tonnes of weed removed, the southern side of Bellandur Lake, once again resembles a water body. But the waters soon disappear into a thick cover of grass. About 120-150 acres of the 910-acre lake is still covered by 25,000 tonnes of grass. Executives of Harvins Constructions Private Limited, the company tasked with de-weeding
Leave the weed cutting on lakes to the professionals, was one common theme at Thursday morning’s Cayuga County Water Quality Management Agency meeting in New York. Invasive species have proved to be particularly difficult to manage this year, and in areas such as Cayuga Lake and Skaneateles Lake, agencies have found property owners with good
