The UCLA study highlights the inadequacies of decades-old infrastructure in the Golden State that were “designed for the climate of the past and not for the rapidly changing climate of the future,” Climate Signals notes.

“Our big dams were designed to capture smaller floods than what we expect in the future,” said Daniel Swain, a UCLA climate scientist and lead author of an earlier study on California’s climate-related weather extremes. “We can make some changes on the margins, but these structures were built for a climate that we no longer have.”

Exeter’s Great Dam Removal :: NOAA Fisheries

Good news for boaters! And everyone!

Friday, September 9, the town of Exeter, New Hampshire celebrates the removal of the Great Dam and the restoration of the Exeter River. The town will hold a public ceremony in Founders Park at 10am.

There have been dams along the Exeter River since the 1640s or so. The Great Dam, named for the nearby Great Falls, was built around 1831 to provide power to Exeter’s mills. After coal and oil power came to Exeter, the Great Dam continued to provide power to Exeter businesses into the mid-20th century. When the dam’s owner sold the dam and factories in 1981, the Great Dam was donated to the Town of Exeter.

With the need for the dam gone, the Great Dam fell into disrepair. In 2000, the New Hampshire Department of Environmental Services advised the town that the dam had serious safety and flooding issues. The Town considered repairing, modifying, or removing the dam, and finally decided that removing the dam was the best solution.
