Oceans & Clean Water

An unconventional gathering helped spur ideas to speed the pace and scale of river restoration projects across the West.

To preserve habitat for fish and benefits for humans, some scientists suggest we need to explore the need for assisted migration.

Removing two aging Eel River dams known as the Potter Valley Project would benefit salmon, lamprey and people, but what happens next remains unclear.

We rely on freshwater plants and animals for clean water, food, recreation and other needs. And yet they’re often overlooked in conservation.

Accumulating sediment in reservoirs is affecting how much water dams can hold back to supply water for drinking, irrigation and flood control.

Can science and tradition finally help heal the region’s peoples and bring balance to its biodiversity-rich waters and mangrove forests?

To anticipate the impacts of a historic river restoration, we need to understand how salmon, bats, insects, algae and other parts of the ecosystem are behaving today.

In north Brazil, the combined effects of a hydroelectric dam and earth-shifting livestock have altered the landscape — and upended peoples’ lives.

A growing movement across the continent is working to remove thousands of barriers and restore some of the world’s most fragmented rivers.

Humble ponds have a key role to play in fighting climate change and aiding conservation — but only if we protect them.
