Forecasted storms expected in the Feather River basin this weekend may require using Lake Oroville’s flood control outlet spillway (also known as the main spillway) this week or next.

Today’s snow survey by the California Cooperative Snow Surveys Program indicates that water content in the statewide mountain snowpack increased from 23 percent of the March 1 average to 52 percent of today’s historical average. The early-April snow survey is the most important for water supply forecasting because the snowpack is normally at its pe ...

The underground secant pile cutoff wall was completed on March 7, 2018 and crews are placing roller-compacted concrete for the emergency spillway splashpad.

As part of ongoing work to improve California’s preparedness for dry conditions and better adapt to climate change, DWR has released results of a study examining Southern California tree-ring data, and the centuries-long story the tree-rings reveal.

DWR and CAL FIRE/Butte County Fire Department have jointly launched three major fuel reduction projects designed to reduce wildfire threat and bolster forest health around Lake Oroville.

Today’s snow survey at Phillips Station tells a more positive story than it did before the recent storm, but totals are still well below average.

The underground secant pile wall is 95 percent complete and is targeted for completion in March of 2018. Foundation preparation continues for the roller-compacted concrete (RCC) splashpad. Phase Two of construction on the main spillway is expected to begin in May.

Today, the Department of Water Resources (DWR) released a Cost-Benefit Analysis for California WaterFix by Dr. David Sunding, a professor of natural resource economics at UC Berkeley, that finds the first stage of the project could bring billions of dollars in benefits to Californians who obtain their water from participating State Water Project (S ...
