SOUTHWICK – The annual algae treatment of South Pond and Middle Pond is Tuesday.
Lake Management Committee member Richard Grannells said portions of both ponds will be chemically treated to control the growth of nuisance algae.
Swimming is restricted until June 26.
“It works really fast,” said Grannells of the treatment.
About 40 percent of those ponds will be treated. Grannells said North Pond is not treated because water frlows from North to Middle to South Pond and North is the deepest, coolest water.
“Algae tends to grow in warm, shallow water,” he said.
There are no restrictions on other lake uses.
“The copper sulfate used in the treatment works very quickly and we are only treating a small portion of the lakes,” Grannells said.
Earlier this month all three ponds that comprise Lake Congamond were treated for other nuisance growth. Solitude Lake Management of Shrewsbury is conducting the treatment.
