Intensive in-lake and watershed management caused Kohlman Lake, the northernmost lake in the Phalen Chain of Lakes in Minnesota, to go from a relatively turbid to a clear water state. Aquatic plants responded to the clean waters by growing up to the surface. The change in lake state and a comprehensive water quality monitoring dataset
Keeping aquatic invasive species out of Montana bodies of water, specifically invasive mussels, is very important to protecting the native fish and plant species in the area. Researchers said cleaning, draining and drying boats is nearly 100% effective at keeping AIS out of Montana. That is why boat inspections are required in the state. Seaplanes
An aquatic weed harvester was used to remove macroalgae from Georgica Pond in New York from 2016 through 2018 and on a limited basis last year, an effort to inhibit harmful algal blooms, including toxic cyanobacteria, or blue-green algae. Approval has just been granted for the the mechanical harvester to be operated from June to
In order to stop the destruction of infrastructure by aquatic invasive species, USACE and its partners are using three methods of management: biological, mechanical, and chemical. Each process varies in its effectiveness depending on the species of aquatic plant being treated – leaving the team to rely heavily on data to determine the best method
Algal blooms in Bednesti Lake, British Columbia, Canada, over recent years led researchers to look into how humans impact aquatic life. Overall what they found was a chain reaction, when a type of aquatic plant like a lily pad was removed, other plants disappeared too. Researchers analyzed 16 human-caused disturbances and 10 natural disturbances to
Around 83% of green turtles and 86% of loggerhead turtles found off the coast of Queensland were found to have plastics within them, a study from Deakin, James Cook and Murdoch universities found. Researchers examined the contents of the stomach, intestines, cloaca and bladder of stranded or captured turtles collected from the Indian Ocean off
Each year, the St. Albans Area Watershed Association uses mechanical harvesters to cut and remove tons of unwanted plant material out of St. Albans Bay. The harvesters scooped up almost 90,000 bushels of plants in 2020 alone. The aquatic weed harvesters are used for establishing things like navigation lanes and clearing out areas of varied
In the last few decades, the lake’s weedy, northern-most portion has clogged hulls and deterred boaters from entering the lake from the Oswegatchie River. Patches of weeds greet the water’s surface near every dock, and nearly invisible from a distance on a windy day, matted greenery creates a basin of weeds seven-feet-deep in some spots.
Some shoreline residents of Duck Lake, Michigan aren’t keen on the continued use of chemicals to treat invasive aquatic plants for fear of unintended consequences. Green Lake Township has for years collected a special assessment tax to pay for Eurasian watermilfoil treatments in Duck Lake, an effort to keep the species’s signature mats of floating
