‘Urgency Change’ Will Allow More Water to Be Stored in Lake Oroville and Shasta Lake

Federal and state water agencies have issued an urgency change to conserve more water in Lake Oroville and Shasta Lake.

District 1 Rep. Doug LaMalfa announced Wednesday, the U.S. Bureau of Reclamation and California Department of Water Resources have issued a temporary urgency change petition. It will be in effect now through June 30.

The urgency petition allows the State Water Project and Central Valley Project to release less water through the Delta, in order to conserve stored water at reservoirs including Shasta Lake, Lake Oroville and Folsom Lake.

How Much Rain Does California Need to Get Out of the Drought? A Lot Still

If you flashback to October, it might seem hard to believe that California’s Sierra Nevada would be experiencing a below-normal snowpack at this point of the winter. During October, the region was regularly pummeled with atmospheric rivers and major winter storms, with those storms dropping feet of snow in the mountains.

But as of early February, despite that strong start, the region has had its driest period of winter in recorded history. It has been more than 32 days and counting since the last snowfall at the U.C. Berkeley Central Sierra Snow Lab, breaking the previous record of 31 set in 1990.

Lake Oroville Rises 89 Feet, Power Plant Resumes Operation After December Rains

After two years of setbacks and struggles due to a severe drought, California got some good water news on Tuesday. The reservoir behind the tallest dam in the state and the nation, Lake Oroville in Butte County, now has enough water in it after heavy December rains that the power plant began operating again.

California Reservoirs Continue to Rise After Major Winter Storms

California has seen big changes in reservoir levels so far this rainy season and the trend is up for the foreseeable future.

At the beginning of the water year for 2020-2021, some major reservoirs, such as Lake Oroville, were at record lows. California’s well-known reliance on water capture and transport was under severe strain until a record October storm provided quick relief.

 

Rain Does Lake Oroville Good

As the calendar prepares to turn into 2022, Northern California is getting covered with snow, and rainfall in Butte County is leading to more water in Lake Oroville.

As of midnight Tuesday, Lake Oroville had 1,323,897 acre-feet of water in it. While that number is 37% of the lake’s capacity, it also reflects 72% of its average storage his time of year.

Here’s How Much December’s Rain Added to Northern California Reservoirs

As a rainy December comes to close, nearly all Northern California reservoirs were still drier than historic averages for this time of year, according to data from the California Department of Water Resources.

But the precipitation still gave several reservoirs a boost from the beginning of the month.

California’s Major Reservoirs Are Still Far Drier Than Average

The just-passed atmospheric river gave California a lot of precious, badly needed water. But how well did our all-important reservoir systems do? For California, water storage, above and underground are the key to California’s economic fate.

As of midnight Monday, California’s major reservoirs keep getting more water from the weekend’s storm as the runoff finds its way into them.

As Drought Worsens, Officials say Mandatory Water Cuts Likely Coming for Urban Californians

With the drought showing no signs of abating, California officials announced Wednesday they plan to deliver almost no water from the State Water Project to begin next year — and suggested that mandatory cutbacks in urban usage could come if conditions stay dry.

Karla Nemeth, director of the Department of Water Resources, said the various cities and farm-irrigation districts that belong to the State Water Project — the elaborate state-run network of reservoirs and canals — are getting “essentially a zero allocation” to start 2022.

 

Spillway Gravel Launch Ramp Reopens as Lake Oroville Rises

As the rain falls down in the watershed, Lake Oroville’s water level rises.

Lake Oroville recovered some of its water over the last two weeks from a recent storm ending a long streak of low lake levels that has lasted since its record low on Aug. 4.

According to a community update from the California Department of Water Resources, the recent storm brought the reservoir’s elevation from 629 feet on Oct. 22 to 658 feet by Oct. 27. The elevation Wednesday was 661 feet.

Opinion: Socal’s Water Planning Offers Lesson for State

Another historic drought has gripped the West and California, with the entire state facing abnormally dry conditions and 87% of it facing an extreme drought, according to the latest federal data. Yet Southern Californians are in far better shape to handle the situation than Northern Californians thanks to policies that southern water agencies have adopted.

Two-thirds of the state’s rain falls in Northern California, which has one-third of the state’s population — and vice versa. Yet many northern cities are running out of water, with several San Francisco Bay Area communities already adopting water rationing and water-use restrictions. This isn’t happenstance, but the result of planning — or lack thereof.
