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.”

Plan Released for Klamath River Dam Removal | American Rivers

https://www.americanrivers.org/2018/06/plan-released-for-klamath-river-dam-removal/

“The Klamath River project will be the most significant dam removal and river restoration effort yet. Never before have four dams of this size been removed at once which inundate as many miles of habitat (4 square miles and 15 miles of river length), involving this magnitude of budget (approximately $397 million) and infrastructure.

But perhaps more important than the size of the dams is the amount of collaboration and the decades of hard work that have made this project possible. American Rivers has been fighting to remove the dams since 2000. And thanks to the combined efforts of the Karuk and Yurok tribes, irrigators, commercial fishing interests, conservationists, and many others, our goal of a free-flowing river is now within reach.”

Biggest dam removal ever! Klamath was largest salmon producer until dams interrupted reproduction cycles.

Section 437 of the bill attempts to block judicial review of all agency decisions regarding the environmental review of a proposed water transfer project in California known as the “delta tunnels project,” or “California WaterFix.”

“In November, the IJC issued a 25-page report advising both governments take decisive steps to protect human health and the environment by reducing polybrominated diphenyl ethers (PBDEs) in the lakes. The brominated flame retardants, which are bioaccumulative and found in many products, have been in use since the 1970s and exposure has been linked to cancers, reproductive health, thyroid, neurobehavioral and developmental disorders.”

Audio: Proposed federal water bill would streamline new dam projects | 89.3 KPCC

http://www.scpr.org/news/2017/01/09/67954/proposed-federal-water-bill-would-streamline-new-d/

The bill would codify into federal law the 1994 Bay Delta Accord, an agreement between state and federal authorities to coordinate water use and quality standards for water in the California Delta, where the confluence of the Sacramento and San Joaquin rivers enters Suisun Bay and flows toward the Pacific Ocean. Making the accord a federal law would restore water deliveries to Central California users that were “cut off by environmental lawsuits and a series of illogical regulations,” Valadao says in the bill’s summary.”

Stream lining dam project process good for farmers but what about the environment?

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.
