One letter-writer from Kennewick, Wash., downriver to the dams, called our salmon recovery plan "the death of reason and common sense." Another writer, tossing in a slap at the Clinton White House, called it part of the Statesman's "continuing cover-up and support for our corrupt administration and the wacko environmental extremists."

Another critic — John Etchart, then-chairman of the Northwest Power Planning Council in Portland, Ore. — called breaching a "long-odds gamble with billion-dollar stakes."

The stakes haven't changed. We're still debating about how to save Idaho's wild salmon, an essential link to our wild heritage and an irreplaceable piece of our river biology. We're still talking about how best to balance the needs of water users with the future of Idaho's rural fishing communities. We're still talking about a fair, forward-thinking balance that removes the dams while replacing the power and slackwater shipping these four dams provide.

But along the way, the proposition of breaching has gone mainstream, for several reasons:

• Dams have been dismantled elsewhere to restore fish and wildlife habitat. More than 465 dams have been removed nationwide, according to the conservation group American Rivers, and this process has continued during the Bush years. For example, in neighboring Washington state, two dams on the Elwha River will be dismantled starting in 2009, restoring more than 70 miles of salmon habitat in and near Olympic National Park.

As a result, there is growing evidence that dam removal performs as advertised, restoring fish habitat.

• Breaching has picked up some surprising supporters.

A recent study — "Revenue Stream: An Economic Analysis of the Costs and Benefits of Removing the Four Dams on the Lower Snake River" — argues that removal will save American taxpayers and Northwest ratepayers $2 billion to $5 billion over 20 years, while generating $9 billion in new revenues. Report co-signers include not only the usual suspects in the salmon advocacy field, but Taxpayers for Common Sense and Republicans for Environmental Protection.

One of breaching's newest and most respected advocates is Don Chapman, a fisheries biologist and longtime consultant for electric utilities. He now argues that the time has come to breach dams and save Idaho wild salmon that have struggled on the feds' endangered species list since the early 1990s.

• Idahoans are split on breaching, as a 2006 Boise State University Public Policy Survey shows.

Thirty-five percent of Idahoans support breaching, the survey says, while 43 percent oppose — a result within the survey's margin of error. When the opponents were asked where they'd stand if the dams' barging network and hydropower were replaced at a similar cost, the support for breaching climbs to 45 percent, and opposition sinks to 31 percent.

While Idaho political leaders remain stubbornly opposed to breaching, Idahoans see the issue differently. This is one issue where the people will need to lead their leaders.

And this must happen because something hasn't changed. Idaho's wild salmon remain in peril, and breaching represents their best shot at recovery.

Last year, 37,636 chinook salmon moved upriver past Lower Granite Dam, the final obstacle to their spawning grounds. In 1997, 46,015 chinook passed the dam.

Breaching opponents may point to their own sets of numbers: a 1997-2006 average run of 66,309 chinook, compared to an average of 22,463 the preceding decade. But the fact remains that Idaho salmon runs have not recovered. That's why, a decade later, the breaching debate is as urgent as ever.

Idaho Steelhead and Salmon Unlimited and the Ted Trueblood Chapter of Trout Unlimited will hold a salmon, steelhead and trout seminar at Boise State University's Jordan Ballroom on Saturday.

The event runs from 9 a.m. to 5 p.m. Admission at the door is $5.

Speakers include Statesman outdoor writer Roger Phillips, who will lead an 11 a.m. seminar on taking good fishing photographs. A panel discussion at 3:30 p.m. will focus on salmon recovery and the Statesman's 1997 editorial series on dam breaching. Speakers include former Statesman editorial writer Susan Whaley and current editorial page editor Kevin Richert.
