Workers Start Repairs On Key Water Pumping Station

Work crews in California have started repairs to a key pumping station in the state’s water system. State officials said repairs at the Clifton Court Forebay pumping station started Wednesday. The Department of Water Resources says the pumps there are being shut down to repair a damaged intake valve. The Clifton Court Forebay is a crucial part of the north-south water system that delivers Northern California water to millions in Central and Southern California. The pumps, pipes and dams in the system have been strained by five years of drought followed by the heaviest rain in decades this winter.

State Dealing With Another Reservoir Fix Near Tracy, Says It Won’t Interrupt Water Deliveries

On rich Delta farmland just outside Tracy, Suzanne Womack spent her childhood on more than 600 acres dating back to 1961. “I moved there when I was 3 years old,” said Womack. “I learned to ride horses there.” Now, for years, her attention has turned to preserving her land against what she calls poor maintenance by the state linked to the massive Clifton Court Forebay fed by the Delta’s Old River, right next door.

Contradiction in Water Policy

In 2016, annual precipitation was average for the Central Valley and above average for northern California. But the allocation of Central Valley Project water to public water agencies that serve farmers south of the Delta was only 5%. The federal government blamed the low allocation of water on hydrological conditions, rather than environmental regulations that limited pumping of water and prevented water from being moved through the system to communities south of the Delta.

VIDEO: A Look At Repair Efforts At The Lake Oroville Dam Spillway This Week

Images from the state Department of Water Resources show round-the-clock work the week of March 11-17, 2017 at Oroville Dam. A giant fracture developed in Oroville Dam’s main spillway during a heavy storm earlier this year. Five days later, water flowed over the dam’s emergency spillway for the first time, nearly causing the hillside below to fail. Approximately 188,000 downstream residents were evacuated for two days.

Can California Repair Damaged Delta Reservoir Within 45 Days?

State officials said Wednesday that Californians reliant on water pumped out of the Sacramento-San Joaquin Delta won’t face supply shortages, even as crews shut down a massive pumping station that serves much of Southern California for at least a month to make repairs to its intake reservoir. The repair effort involves Clifton Court Forebay, a shallow reservoir that serves as an entryway for a Delta pumping station critical to the State Water Project, the state-run water delivery network that moves water north to south through California.

Wet Winter Fails to Solve California’s Forest Problems

Despite the wet winter and far-above-average Sierra Nevada snowpack, California forests remain at risk from tree mortality, bark beetle infestations and overgrown landscapes, according to presentations at the 2017 California Farm Bureau Federation Leaders Conference.(Left) Timber operator and Tuolumne County Farm Bureau President Shaun Crook during the California Farm Bureau Leaders Conference in Sacramento. Photo/Ching Lee. During the event, foresters and forest landowners discussed all those issues and communicated concerns directly to Randy Moore, U.S. Forest Service Pacific Southwest regional forester, who participated as a guest speaker.

Has Lake Tahoe Ever Looked More Beautiful Than It Does Right Now?

A powerful and unrelenting winter blast coated the Northern Sierra Nevada this winter. Back-to-back storms buried the Lake Tahoe area in snow, crippling transportation, shuttering ski resorts, knocking out power and disrupting the daily lives of thousands. In the first three weeks of January alone, the region received nearly a full winter’s worth of snow, and then came February, and the Sierra Nevada was slammed yet again with moisture-packed storms fueled by weather systems known as atmospheric rivers.

Area Water Basins Still Hovering At Record Low Levels, Managers Say

While this winter’s precipitation was good news for Northern California, that story doesn’t translate to much of the Inland Empire, area water managers said Tuesday. “The precipitation that refills our underground storage basins is actually below average, so far,” said Bob Tincher, manager of water resources for San Bernardino Valley Municipal Water District. “So if it were to stop raining today, even with the wet year in Northern California, our groundwater storage levels could actually decrease again this year.” The Inland Empire needs three consecutive above-average precipitation years to refill local groundwater basins, he said.

 

NID: Snow ‘Reservoir’ In Good Shape – This Year

Mitch Brown jammed the blade of his loader into a two-story pile of snow outside Donner Ski Shop, the sports rental store he runs. From there, Old Highway 40 toward bustling ski resorts was lined with walls of snow more than 20 feet high. “It snowed nearly 24 feet in 12 days,” Brown said recently. “We’ve been working 18-hour days to clear it. This winter’s bumper crop of snow — on the heels of the worst drought in 500 years — underscores the threat to this central source of water for western Nevada County and most of California.

Damage At Contra Costa County Reservoir Halts Pumping

The extraordinary volume of water pouring through California’s rivers and reservoirs this winter appears to be behind more damage to the state’s water infrastructure. State officials said Tuesday that an intake structure at Clifton Court Forebay, a 2½ mile-wide reservoir in eastern Contra Costa County, would be shut down because it needs repairs after heavy inflows.
