Oregon dam's demise lets the Rogue River run

Savage Rapids Dam, the cause of fights and lawsuits for years, is finally torn away, as across the U.S., the the era of dam-building of the early 20th century has given way to a new era of dam breaching.

GRANTS PASS, ORE. — For years, the water stored by the Savage Rapids Dam has nurtured the green bean fields and grazing pastures of southern Oregon, turning them into a lush region of bounty.

But there has been a price: the death of thousands of fish, which slammed themselves into the concrete wall of the dam in a futile effort to head upstream.

Those scenes from years past now resemble a faded sepia-tone photograph. Many of the big farms have turned into 10-acre hobby ranches; the salmon are in danger of disappearing; and even the federal Bureau of Reclamation, the agency that harnessed rivers and irrigated the West, began saying a few years ago that it would be better to just tear down the dam once and for all.

So they did.

On Friday, a platoon of bulldozers and earthmovers tore away at the last of the temporary earthen berms holding water behind the dam. The Rogue River rushed free, flowing through its historic channel for the first time since 1921.

"Starting through," muttered Robert Hamilton, regional project manager for the Bureau of Reclamation, who worked on the dam for more than 20 years, fixing and then finally dismantling it. "Don't see something like this every day."

Across the U.S., the era of dam-building that characterized the early 20th century has given way to a new era of dam breaching.

Here in the Pacific Northwest, where some of the biggest battles over fish and concrete have raged, the Marmot Dam on the Sandy River near Portland was demolished in 2007. An agreement was reached last month to remove four dams on the Klamath River in California and Oregon in what is described as the world's biggest river restoration project. Two dams on Washington's Elwha River are slated for removal in 2012.

In southern Oregon, Savage Rapids is one of four dams being dismantled on the Rogue River. With Friday's breaching three projects are complete, and the fourth, Gold Ray Dam, 18 miles upstream from Savage Rapids, could be brought down by next year, returning a 157-mile stretch of the river to its natural state.

Savage Rapids "has been known as the No. 1 fish killer on the Rogue River," said Bob Hunter, who spent 20 years as a staff attorney with the environmental group WaterWatch, working to bring the dam down. "It's the first dam migrating salmon and steelhead meet on their way upstream, and pretty much everyone in the fishing community knew this dam was causing a great deal of harm."

But the 30-foot-high, 500-foot-long irrigation dam was also providing cheap, needed water to farmers and homeowners in the Grants Pass Irrigation District, which had held a legal right since 1918 to a share of the Rogue's waters.

Over the last two decades, rural southern Oregon had been plagued by lumber mill closures resulting from cutbacks in logging to protect the endangered spotted owl; few in the area were initially enthusiastic about losing their water to the threatened coho salmon, one of several species of salmon and steelhead trout that migrate up the Rogue River.

Many families enjoyed boating and water-skiing on the picturesque 3 1/2 -mile reservoir behind the dam.

"It became, I guess, our Statue of Liberty," said Dan Shepherd, manager of the irrigation district, which spent years fighting to preserve the dam.

But the combined power of the environmental movement, the federal government, the simple economics of water and concrete, and a new population that wants its rivers wild, not tamed, became too massive to fight, he said. "It was either you go out of business, or you reinvent yourself and go forward."

The fights seemed endless. Two fishing organizations filed a challenge to the district's application several years ago to expand its water rights. The National Marine Fisheries Service sued the irrigation district, accusing it of illegally killing salmon protected by the Endangered Species Act. The district filed suits of its own trying to keep the dam.

The aging edifice became a bellwether for conservative state lawmakers from the region who were determined to protect it, and former Democratic Gov. John Kitzhaber, who pushed to let it go.

Michael Lambert, a fish passage engineer for the state Department of Fish and Wildlife, went to the dam to take a look for himself and came to the same conclusion the federal Bureau of Reclamation did: It would be cheaper -- and better -- to simply tear it down.

Hamilton described the damage to fish: "You could see the fish try to come up here and try to leap over a 40-foot dam. They'd hit the spillway and fall back down." In other cases, fish would struggle to climb the dam's rudimentary fish ladder -- meant to help fish migrate past a barrier -- but would fall out and die. Young fish migrating out to sea would get trapped in the water pumps' screens and perish.

The Bureau of Reclamation concluded that it would be cheaper to remove the aging facility and build electrically powered pumps in the river to get the Grants Pass district the water it needed.
