The Town of Concord reports on July 17, 2026:: We have received a few bloom reports and can confirm that we have a small bloom within Thoreau’s cove. From samples taken at Thoreau’s cove this week, we observed Microcystis and confirmed the presence of toxin within the collected material. Yesterday we tested the cove for Microcystis and found low to moderate toxin. We then tested at the Town beach and the sample showed less than 2.5ppb - not detectable with our test. We co

The weather has been perfect for White Pond's beaches and waters, but low tides and unenforced rules have brought trouble to the pond's fragile ecosystem. Here's a roundup of wins and losses at the end of June. Win: The Town of Concord got the A-Pod in the water at the end of May. While this was later than ideal, it wasn't bad.

In 2025 alone, two “Sentinel” A-Pods removed 132 pounds of tree pollen and forest debris from the pond before those materials could decompose and

It's been known for years that the supply of trout stocked by the MA Division of Fisheries and Wildlife at White Pond does not correspond to the number of people actually interested in fishing. Divers have reported large number of dead fish at the bottom of the pond, and our counts of fishermen from 2022-2025 year-round don't suggest any change. The time has come for the state to stop stocking trout at White Pond altogether. A big caveat before we continue: we think that fish

On a frigid winter morning at White Pond, the water is still and the air carries the sharp bite of March cold. For many people, the idea of stepping into that icy water would be unthinkable. But for some local Concord residents, the ritual has become a daily source of renewal. “I do it because it makes me feel better every single time, no matter what,” said one interipid plunger. Another swimmer’s journey into cold water didn’t begin with an extreme plunge or a New Year’s res
