Historic Dam Removal

Elwha Dam. Retrieved from: www.nationalgeographic.com

For 98 years, the 125-foot high Condit Dam in southeastern Washington State held back the White Salmon River, creating a serene lake, but choking off the waterway to salmon. Wednesday, in an historic effort, the dam was dramatically breached, and ecologists hope the increased flow of water will restore the waterway to fish and other aquatic organisms, as well as the birds and mammals that rely on them.

The dam removal comes just weeks after dismantling began on the Elwha Dama few hours to the north. Demolition of the Condit occured with a bang, compared to the virtual whimper of the Elwha. At that site, downstream from Olympic National Park, engineers are dismantling the two dams slowly, in a process that’s expected to take three years. They say a quicker removal would endanger the area due to the higher amount of silt in the lake.

Silt is still readily apparent in the dramatic video above, both in the darkly colored water rushing from underneath the conrete and in the fast-emptying lake.”

Restoring Iraq’s Wetland Marshes to the Original Eden

“A place so beautiful, teeming with water and life, that according to the Christian faith it was the birthplace of mankind.

That was until the 1980s, when Saddam Hussein drained these great wetlands of southern Iraq, destroying them, turning them to desert.

However, since his overthrow, a remarkable effort has begun to restore these Mesopotamian Marshes, among the most important wetland habitat in the world.

One man is leading the way, attempting to rejuvenate the marshes and bring back the diversity of animals and plants that once lived there.

A BBC film crew has followed his progress, revealing how he and his colleagues are succeeding in attracting rare birds back to a land ravaged by persecution and war.

In the 1990′s Saddam Hussein drained the wetlands to punish the indigenous Marsh Arab tribes, who had risen against him in the aftermath of the first Gulf War.

He built a network of canals to channel water from the Euphrates and Tigris Rivers around the marshes, dumping it straight into the Arabian Gulf.

Within a matter of months, the marshes, which had covered 15,000 square kilometres, were reduced to less than 10% of their original size.”
