Tom Rickey, PNNL Fish-friendly hydropower is the goal of international team Think of the pressure change you feel when an elevator zips you up multiple floors in a tall building. Imagine how you'd feel if that elevator carried you all the way up to the top of Mt. Everest — in the blink of an eye. That's similar to what many fish experience when they travel through the turbulent waters near a dam. For some, the change in pressure is simply too big, too fast, and they die or are...

BOLSHIYE KOTY, Russia - The world's oldest, deepest and biggest freshwater lake is growing warmer, dirtier and more crowded. Lyubov Izmestieva is charting these insidious changes.

By Darren Schuettler PAK MUN RIVER, Thailand (Reuters) - Mekong fish don't jump. It was one of the many hard lessons learned at Thailand's Pak Mun Dam, a minnow as dams go, but it casts a long and costly shadow over Asia's water wars.

While much of the world has focused on the war in Iraq, a group of wetland ecologists has been busy collecting data on the Mesopotamian marshes of southern Iraq. Formerly the largest wetland in Southwest Asia, the marshes are home to the native Ma'dan marsh dwellers, as well as numerous species of migrating waterfowl and game fish. Drainage of the wetlands as well as toxic contamination over the last twenty years devastated much of the marshlands. A mere 10 percent remain as viable wetlands....

WASHINGTON (AFP) -- Nearly one fifth of the Mesopotamian marshes of southern Iraq, almost completely drained by Saddam Hussein, are once again flooded with water, according to experts working on an international effort to restore the wetlands. Considered the cradle of western civilization -- the location of the Garden of Eden, according to scholars of the Bible -- the marshes, fed by the Tigris and Euphrates rivers, are key to the economy, politics and ecosystem of the region. "The future...
