Lake Whitehall Plan Targets Invasive Weeds With Herbicides and Harvesting

Tue, 21 Dec 2021 20:57:26 +0000

The Massachusetts Department of Conservation and Recreation is aiming to reduce invasive plant species in Lake Whitehall in a plan that calls for herbicides and mechanical harvesting.

The reservoir has extensive growth of “exotic nuisance aquatic vegetation,” including fanwort and variable-leaf milfoil, according to a report by ESS Group, a firmed hired by the state.

The planned management program calls for herbicide treatments, mechanical harvesting, hand and diver harvesting, and benthic barriers, a method that uses sediment.

“DCR is also seeking approval for the use of algaecide treatments should they be necessary to control algae blooms following the management of aquatic invasive plant species in the reservoir,” the report reads.

Copper Sulfate Algae Treatment Leads to Fish Kill in Colorado Reservoir

Colorado Parks and Wildlife is investigating Johnstown officials after their attempt to treat an algae outbreak left nearly 1,000 fish dead.

The Greeley Tribune reports that Parks and Wildlife spokeswoman Jennifer Churchill says a worker put a copper sulfate into the town’s reservoir this summer to treat the algae. She says chemical ended up suffocating 972 fish.

The National Pesticide Information Center says copper sulfate can cause sudden plant death, causing fish to suffocate because of depleted oxygen and clogged gills.
