[Oroville] Dam operators gradually scaled back water releases to zero over a six-hour period, providing breathing room for construction crews trying to clear debris from a badly choked Feather River channel and restart the dam’s critically needed hydroelectric plant.
Oroville Dam operators plan to halt water releases from the dam’s battered spillway Monday in order to ramp up efforts to remove a debris pile that’s preventing them from restarting a hydroelectric plant.
Water releases through the damaged main spillway at Oroville Dam were scaled back Thursday to allow crews to reach and remove a pile of debris that has built up at the bottom of that chute, officials said.
Feeling confident they’ve created sufficient empty space in Lake Oroville for the time being, state Department of Water Resources officials said they reduced spillway outflows so they could address another looming challenge: restarting the dam’s hydroelectric plant, which can release additional water when operational.
NextEra Energy Resources is working to build a massive hydropower plant just outside Joshua Tree National Park, bringing the weight of one of the country’s biggest renewable energy companies to a controversial project that critics say would harm wildlife and diminish an underground water supply critical to the park.
Whiskeytown Lake, a major reservoir in the foothills of the Klamath Mountains nine miles west of Redding, was built at the site of one of Shasta County’s first Gold Rush communities. Whiskeytown, originally called Whiskey Creek Diggings, was founded in 1849 and named in reference to a whiskey barrel rolling off a citizen’s pack mule; it may also refer to miners drinking a barrel per day.
As one of the most productive agricultural regions in the world, the Imperial Valley receives its water from the Colorado River via the All-American Canal. Rainfall is scarce in the desert region at less than three inches per year and groundwater is of little value.
Hydropower in the United States is primed for a shakeup. On one hand, utilities and governments are tearing down old dams with increasing frequency. … On the other hand, lawmakers and officials are keen to wring more power from rivers.
Earlier this year, in an announcement that has become more routine around the world, Suy Sem, Cambodia’s minister of mines and energy, declared a moratorium on the construction of big hydropower dams until at least 2020. … Cambodia joins a lengthening list of nations around the world that are reassessing big hydropower dams in an era when wind and solar power are less expensive, much easier to build, less damaging, and far less vulnerable to droughts and floods.

Salmon leap over rocks and other small obstacles as they swim up the Tuolumne River to spawn every fall. But they cannot surmount the 110-foot-tall dam that created La Grange Reservoir, much less the 585-foot dam just upstream at Don Pedro Reservoir.
Flying over the Sierra Nevada as California entered its fourth year of drought, the state’s energy chief looked down and saw stark bare granite cloaked in dirty brown haze – not the usual pristine white peaks heaped with snow that would run the state’s hydroelectric dams for the year.
Two major developments in the [Yuba County Water] agency’s history were coming to a head — the application for a new license that will determine how the water project is run for the next 50 years and the takeover of the operation of the project’s hydropower plant.

Many Californians don’t realize that when they turn on the faucet, the water that flows out could come from a source close to home or one hundreds of miles away. Most people take their water for granted; not thinking about the elaborate systems and testing that go into delivering clean, plentiful water to households throughout the state. Where drinking water comes from, how it’s treated, and what people can do to protect its quality are highlighted in this 2007 PBS documentary narrated by actress Wendie Malick.

Hydroelectric power is generated by the ability to turn falling water into electricity and in California accounts for about 15 percent of the state’s power supply annually.
Hydroelectric power is produced when water turns a turbine connected to a generator. This water is stored behind a dam at elevation. Gravity causes water to drop toward a turbine propeller. The falling water turns the turbine which produces power through the connected generator.
In California, the State Water Project provides water for 25 million Californians and irrigation water for an estimated 750,000 acres of farmland. Along the way, it supports industries from agriculture to high tech that make the state a global economic powerhouse.

This printed issue of Western Water looks at the energy requirements associated with water use and the means by which state and local agencies are working to increase their knowledge and improve the management of both resources.
Diverting water for farms and cities, generating hydro-electric power, supplying an ever-growing urban population and protecting endangered species have all shaped the development and management of the Colorado River we know today. How to sustain the system and build a resilient future for what is known as the “lifeline of the Southwest” is the task facing the region and the river’s multiple users.
Hydropower generation is prevalent in the West, where rapidly flowing river systems have been tapped for generations to produce electricity. Hydropower is a clean, steady and reliable energy source, but the damming of rivers has exacted a toll on the environment, affecting, among other things, the migration of fish to vestigial spawning grounds. Many of those projects are due to be relicensed by the Federal Energy Regulatory Commission.
The vital importance of water in the West is a given. It is the basis upon which everything moves forward – the burgeoning subdivisions, the seemingly limitless acreage of fruits and vegetables and the remaining stretches of wilderness that support fish, fowl and wildlife. In addition to its life-sustaining properties, water, more specifically the force of moving water, plays a significant part of the nation’s power system by providing an inexpensive, reliable and renewable generation source.
Those on the California water insider track know all too well the fine line the state walks with regard to maintaining its water supply. Hydrologic conditions put California at the mercy of the weather and some are predicting this year could be the start of a dry cycle not just for the state, but the Southwest as a whole. Combine that with a regional dry spell in the Northwest and California’s power woes, and a potential recipe for disaster begins to solidify.
