Santa Clara Valley Water District asks voters for $682 million parcel tax for floods, dams, environmental projects

After years marked by a historic statewide drought and devastating floods around downtown San Jose, Santa Clara County’s largest water provider has decided to ask voters to approve a parcel tax to pay for a wide variety of projects, from flood control to creek restoration, along with some costs of rebuilding the county’s largest dam at Anderson Reservoir.

Decline in Hydropower Hampered by Drought Will Impact Utility Costs

Hydroelectric power from dams usually provides about 15% of California’s electricity needs. But in 2015, at the zenith of the worst drought in California’s recorded history, it supplied only 6%.

Another Washington Dam Removal — and 37 More Miles of Salmon Habitat Restored

PILCHUCK RIVER, near Granite Falls, Snohomish County — Washington’s dam-busting summer is still rolling, with two more dams coming down on the Pilchuck River, opening 37 miles of habitat to salmon for the first time in more than a century.

The $2 million dam removal project is a collaboration between the City of Snohomish and Tulalip Tribes, and will benefit multiple species of salmon, including threatened chinook salmon, crucial food for endangered southern resident killer whales.

It’s the state’s second dam teardown project in two months. In July, the city of Bellingham blew up its Nooksack Diversion Dam on the Middle Fork of the Nooksack River, opening 16 miles of habitat for salmon, including chinook.

Newsom Lays Out Big Dreams for California’s Water Future

Touting ways to shield California’s most precious resource from climate change, Governor Gavin Newsom released strategies Tuesday to improve drinking water quality, revive a stalled multibillion-dollar tunnel and build new dams.

Migratory River Fish Populations Plunge 76% in Past 50 Years

Populations of migratory river fish around the world have plunged by a “catastrophic” 76% since 1970, an analysis has found. The fall was even greater in Europe at 93%, and for some groups of fish, with sturgeon and eel populations both down by more than 90%.

As Flood Season Settles In, Experts Shed Light on Dam Safety Problems

U.S. dam safety frameworks have helped to prevent major calamities, but the May collapse of the 95-year-old Edenville Dam in Michigan illustrates that key failure risks remain—often involving many causes, according to a study of dam safety risk assessments by Oak Ridge National Laboratory.

To Dam or Not to Dam

For the past two decades, dams have been falling across the United States in a bid to reverse a legacy of destruction of fish and their habitat. American Rivers, a nonprofit advocacy organization, estimates that 1,200 dams were dismantled nationwide from 1999 to 2019, including major dams on the Elwha and White Salmon Rivers in Washington State.

Damming Up Water Progress Throws California’s Future Into Limbo

Get ready… here comes the true California water cycle: It begins with headlines and quotes warning of pending disaster based on what could, might, maybe, or possibly happen over the state’s water infrastructure.

It follows with attacks against a single water district, then moves to a concerted effort to convince the average Joe that making a profit in farming and being successful should be accompanied by deep regret and guilt.

Thousands Fled for Their Lives When Two Michigan Dams Collapsed. More Disasters Are Coming, Experts Say

The urgent evacuation of 10,000 people from communities below two failing dams in central Michigan last month prevented the loss of life, but the collapsed dams expelled billions of gallons of water from two large lakes, sending them hurtling downstream in a powerful rush of destruction. Water ripped buildings off their foundations, smashed and twisted roads and bridges, damaged or destroyed an estimated 2,500 properties and triggered fears of contamination as it swept by a chemical plant and hazardous waste sites and submerged downtown Midland — a city of 40,000 people — under 9 feet of water.

Escondido Discusses Rehabilitating Lake Wohlford Dam

The Escondido City Council met on June 3 to discuss options for rehabilitating Lake Wohlford Dam, instead of building a replacement dam, and to award contracts for the Lindley Reservoir Replacement Project.

The council heard a report on the possibility of rehabilitating the Lake Wohlford Dam, which was first constructed in 1895 as part of Escondido’s local water system, to address seismic deficiencies rather than replacing the dam altogether.

According to the report, replacing the dam would cost more than $46.4 million, an amount much greater than the 2012 preliminary cost estimate of $30 million. Furthermore, it would cost an estimated $3.5 million to offset known negative impacts to the environment.
