November 7, 2020
When it was last relicensed, the owners of Treadwell Mills dam on the Saranac River put in a fish ladder so salmon could get through.

This 150-acre lake is a popular venue for anglers, boaters, hikers and birdwatchers.

By Tim Rowland
November 16, 2018
The double-crested cormorant made a miraculous recovery after the ban on DDT, a pesticide that had once imperiled the bird’s existence. But while conservationists hailed the return of birds such as the bald eagle, they became increasingly wary of the collateral success represented by the cormorant.
Accelerating climate change threatens Adirondack fish
October 29, 2018
Some parts of the world, including much of North America, outpace the global average in large part because much of the planet is covered by water and it takes more energy to warm oceans than land. That explains how the Adirondacks can be so far ahead of global change.
