You know, as already mentioned, the fire dept had a truck down at the pond, last week, and was spraying water high up the air and out onto the pond, closer to the Snow's Brook inflow. They could jury-rig a device to add powdered chlorine into the water stream and spray it out onto the pond water and shock the 7-acre pond. Walmart or Ocean State Job Lot has big buckets of powdered swim pool chlorine.

Where there's a will, there's a way to send that no good duck itch parasite straight to parasite hell! (Just hum that old 1975 Jaws-movie ....

Seeing a big number of Mallards, 45-50 ducks, all lined up on the sandy beach like that, two nights ago on Friday at 9:15, trying to catch and eat something present in the water strongly points the blame at these ducks that flew in from somewhere. They left many small white downy feathers in the sand at the water's edge.
