The largest-ever dam removal is underway, a milestone in the nation’s reckoning over its past attempts to bend nature to human will

It was a small moment, with little fanfare, in one of the most remote patches of northern California. Just the rat-a-tat of three Caterpillar excavators gnawing through concrete signaled the beginning of the largest dam removal project in the history of the country, and perhaps the world.

The Klamath River dams, built between the early 1900s and 1960s, fundamentally reshaped one of the West’s most […]

Rooted in Roman law, the public trust doctrine recognizes the public right to many natural resources including “the air, running water, the sea and its shore.”

The public trust doctrine requires the sovereign, or state, to hold in trust designated resources for the benefit of the people.
