The Lake of the Woods dam: Will it ever be fixed?
Date published: 2/9/2009

LAKE OF THE WOODS isn't exactly New Orleans, and hurricanes like Katrina don't come along very often. Still, the water-oriented Orange County community must do what it can to prevent loss of life and property due to a dam breach. Even if the fix is costly.

Wasn't that the lesson learned from the 2005 Gulf Coast disaster? Experts knew the levees around New Orleans could fail in a big storm, allowing the city to flood. Nothing was done, and Hurricane Katrina turned the Big Easy into a big punch bowl.

Word that Veterans Memorial Dam at Lake of the Woods is deficient isn't exactly news. The dam, built in the late 1960s, was inspected 10 years later by the Army Corps of Engineers, which classified it as an "intermediate-size, high-hazard structure." The dam's spillway could accommodate only 67 percent of the recommended capacity, noted the 1979 report.

In 1987, the state Soil and Water Conservation Board issued a conditional permit, noting the structure's failings, and two years after that, the Lake of the Woods Association said it would fix the problem.

Since then, LOWA and the state have been throwing that fix back and forth like a hot potato. Twice LOWA's engineer pleaded for time to figure out a reasonable solution, and twice the SWCB reclassified the dam to accommodate that request--creating a 12-year delay. More stalls followed: LOWA even lobbied to get the state regulations regarding dams rewritten to avoid building an expensive new spillway. It was successful after a fashion--the regs were revised, but LOW didn't benefit from the revision.

Now, 30 years after the Corps of Engineers first noted the deficiency, LOWA has finally agreed to bite the bullet and build a new spillway at a cost of $5.6 million. Let's just say that's a tad more than if it had complied when the deficit was originally noted. Now, some fancy footwork may be required to find financing. Regardless, the fix has to happen.

The dam, one of two owned by LOWA, is classified as "high hazard" because a failure would result in a probable loss of life and extensive property damage to the nine homes and numerous other structures downstream. Granted, it would take an extraordinary weather event to endanger the dam, but Katrinas happen, even here in Virginia.

In 1995, torrential rains caused Timberlake Dam in Campbell County to fail, killing two people and causing extensive property damage. And in 1999, Hurricane Floyd, which dumped 24 inches of rain in Franklin in 30 hours, caused a dozen dams in eastern Virginia to give way.

The law is clear: It's the responsibility of dam owners to ensure they comply with state regulations. Lake of the Woods has had a 30-year stay of execution. Now it's time to dig deep and fix the dam.

Please get your history right. The rainfall at Johnstown was not anywhere near that predicted at LOW. The rich owners were irresonsible and selfish for sure. They stocked the reservoir with fish. They feared the fish would be washed over the spillway and they would lose their precoius fish and fun, so they erected a screen to keep the fish in the reservoir. The flood carried debris that was gtrapped by the screen and blocked the spillway. That caused the dam to overtop and fail.

I was born and raised in Johnstown. I read McCuoolch's definititive study about the flood. I saw the high water marks all o0ver the town. It rained and rained and rained for days before the dam let go. Rich pukes like carniegie were TOO CHEAP and UNCONCERNED ABOUT HUMAN LIFE JUST LIKE LOW. The South Fork dam was rebuilt on the cheap, just like LOW's, who seem to have dues $ for their golf course.

property of the county? (posted by grannyof10 , Feb. 10, 2009 8:08 am)    0 likes
Take a look at MONTCLAIR in PW county, north the 'Burg on 234. Their ammenities make LOW look like a hole in the wall. What a beautifully managed/maintained golfing community, pools, lake and clubhouse! It takes TENS OF MILLIONS ANNUALLY to maintain such a community, and it got to be more than THEY could afford annually in HOA fees too. The county took over, and the rest is history.

You should learn your history. The failure of the dam that caused the Johnstown flood was not caused by a torrential rain like the one postulated for the LOW project. It was caused by a screen across the spillway that the owners erected to prevent their precious fish from escaping that trapped debris and reduced the spillway capacity. The actual rainfall was a fraction of the predicted rainfall that will cause LOW to build a new spillway, which is Weather Service data that is questionable at best.

More comprehensive reporting would be helpful (posted by larryg , Feb. 9, 2009 1:34 pm)    0 likes
A graphic showing the floodway and the homes and other property potentially affected would help everyone better understand the relevancy of the regulation. I'm not convinced that there are not several potential solutions - for instance buying the potentially affected property... this editorial touched on something that seemingly contradicts previous reporting - which implied that the dam was ok when constructed but regs got much tighter and it could not be grandathered.
