Dam Removals In Vermont Accelerate In The Age Of Climate Change

The old dam in West Rutland, Vermont before
demolition began this summer. The dam
was removed to improve stream ecology
and prevent flood damage. Old dams
in Vermont are coming under more 
and more scrutiny in the age of 
climate-change driven floods. 

 Back in high school, I briefly had the worst job I ever had.

There was a town reservoir in West Rutland, Vermont that was a municipal water supply. The reservoir was temporarily drained, and we had to muck out the algae and mud left behind to ensure future water quality. 

YUCK!

The town no longer uses that water supply. And I have to say West Rutland now has some of the best tasting tap water of any town I've tried. 

But the dam was still there. Or was. Work began earlier this summer to tear it down. Part of the reason is climate change, of course! 

The dam was growing more and more unsafe due to its age and the increasing severity of rain storms created in large part by that climate change. 

 As WPTZ reports:

"Officials said because of the dam's outdated infrastructure and old age, parts are breaking off during storms and changing the direction of the river. West Rutland Town Planner Mary Ann Roulette said the dam has caused major disruptions over the years. She revealed there as minor damage affecting nearby property this past July."

Karina Dailey, a restoration ecologist and chair of Vermont's dam task force said the West Rutland deconstructions  is one of several dam removal projects. Others are getting going in Newport, Ripton, Berkshire and Winooski. 

DAM SCRUTINY

Communities statewide are discussing removing dams, perhaps hundreds of them. Usually in the name of river health, and the fact removing these small dams can minimize flooding in climate-driven storms. 

 "The best resilience is to let these rivers function naturally," Dailey said. 

Sure, we're having a drought now, but it's only a matter of time before we start running into those super charged rainstorms again. 

It's interesting this is going on now as some Vermont dams were built almost a century ago after the cataclysmic Great Flood of 1927.  

Large flood control dams like Wrightsville, Waterbury and East Barre were built after that flood. Montpelier suffered extensive damage in the July, 2023 flood, but the Wrightsville Dam helped prevent the water from being even deeper. But that dam was almost overtopped in 2023, and that would have caused an even more cataclysmic inundation.

Still, those large dams did their jobs in 2023 and 2024 and did protect some property. It's the small dams that are causing problems. 

In the 2023 floods, five Vermont dams failed and 60 were overtopped. That event has put new urgency into efforts to remove old dams. 

As Vermont Public reported in a separate article, Vermont has more than 1,000 dams around the state. Many are overdue for repairs or are old and becoming dangerous. As those climate induced storms intensify, those dams become more unstable, and can collapse under heavy rains, worsening damage. 

Even if these old, unstable dams don't collapse during floods, they can create damage in heavy rain storms. 

"Dams not created specifically for flood protection are regularly full and do not provide storage capacity. And they frequently direct water outside the main channel at high velocities which causes bank erosion and impacts to communities,"  said Andrew Fisk, the northeast regional director for the environmental advocacy group American Rivers.

Which is precisely why that dam in West Rutland was removed, and many other dams in Vermont are on their way out. Or, dams like ones recently removed in Dover, and another in Ripton were taken out for ecological reasons. But those removals had the happy side effect of minimizing damage from future floods.

MONTPELIER

Flood-prone Montpelier is looking at removing old dams and has already started on one. 

The Pioneer Street Dam is about 1.3 miles upstream from downtown Montpelier. It's cracked, could collapse in a flood, and could redirect water toward homes and businesses even if it doesn't get smashed down in a future flood. 

Also this summer, right near the Pioneer Street Dam, deconstruction work started on a 19th century home that was on property that once belonged to Jacob Davis, the founding settler in Montpelier was deconstructed.

The property located at 5 Home Farm Way, about two miles upstream from Montpelier consists of a high style Greek Revival house with an attached barn and 19 acres of agricultural land. 

Bricks and planks from the home are being resold for new construction elsewhere. Removing the home and barns opens up new floodplain space, allowing water to spread out over fields before reaching Montpelier during torrential storms. 

Vermont usually tries to preserve historic buildings, but sometimes, there's a greater good that overrides that. "The highest and best use of a floodplain is to serve as a floodplain, said Ben Doyle, president of the Preservation Trust of Vermont, reports Vermont Public. 

Between the removal of the Pioneer Street Dam and the old house, the Winooski River will have more opportunity to spread out into floodplains during big storms before some of that water could reach downtown Montpelier. 

There are three other old mill dams upstream of Montpelier that should be removed, advocates said. They no longer serve the purpose they once did a century ago. They don't even hold back water. The space behind the dams are filled with silt. 

Time for them to go.
