State water board to hear Lake Tahoe pesticide proposal

The California State Water Resources is scheduled to vote on a proposal that would allow the use of aquatic pesticides at Lake Tahoe under certain circumstances. The State Water Board is scheduled to consider the amendment to the Lahontan Regional Water Quality Control Board’s Basin Plan during a May 15 meeting in Sacramento. The regional water board approved the plan in December. Existing rules effectively prohibit pesticide application to water within the agency’s jurisdiction.

DEC Begins Emergency Rule-Making for Hydrilla Infestation Treatment

ALBANY, NY — The New York State Department of Environmental Conservation adopted an emergency rule to allow for herbicide treatment to combat hydrilla, an invasive plant species that has plagued parts of the Cayuga Inlet since last summer, the agency announced today.

“Immediate action is necessary to stop the spread of hydrilla to preserve native plants and indigenous aquatic ecosystems throughout New York state,” said DEC Commissioner Joe Martens. “By amending the regulation to allow the use of fluridone pellets, DEC is helping control the infestation of a destructive species that threatens the Finger Lakes economy and habitat.”

DEC Adopting Emergency Measures To Stop Hydrilla

Albany, NY (WIBX) – Boaters and fishermen aren’t the only ones battling hydrilla in some of New York’s waters. The Department of Environmental Conservation is joining the fight, too.

According to the agency, emergency regulations have been adopted to stop the invasive plant’s spread through the Cayuga Inlet.

The new rules allow fluridone pellets (an aquatic herbicide) to be added to water less than 2 feet deep for 90 days, to treat existing hydrilla. The DEC will then renew the measures until a permanent rule is made.

Toxic rift over drift

Felicity Fitz-William awoke to the rhythmic thump of a distant helicopter one day last April. It sounded like an average fly-by until she heard it coming closer and closer. As the noise grew to a thunderous roar, she jumped from her bed to see a chemical spraying helicopter with full booms extended, landing in the paddock across from where she was staying in Ligar Bay. She grabbed her chemical mask and phoned her daughter in tears begging to be picked up and taken away from the danger she knew would make her ill.

PLYMOUTH — Plans to remove invasive weeds from Billington Sea will restrict boat traffic on the West Plymouth pond through the middle of the summer. Workers installed a curtain net Thursday that will separate Billington Sea’s western bay from the main body of the pond. The netting will enable the treatment of that bay with an herbicide that will kill two different types of invasive weeds that are choking the bay.
