Officials give update on Oroville Spillway reconstruction

The Department of Water Resources revealed new information over a conference call to media on Wednesday about the reconstruction of the Oroville Dam Spillway.

DWR says they don't expect needing to use the spillway to lower the water level of Lake Oroville, even with the recent storms.

They say the lake is currently at 809 feet, and that spillway use isn't necessary until water levels reach 830 feet.

Questions were asked about the seepage recently seen on the spillway.

DWR officials say the seepage was expected after the rains, and that it won't be a problem going forward.

The seepage resulted from porous concrete that was temporarily applied during phase one of the spillway project. Officials from Kiewit, a construction company, say they'll be using high-grade permanent concrete for phase two.

Although the operations plan calls for using the spillway as little as possible until it's complete, DWR says the spillway can handle 100 thousand cubic feet of water per second, if necessary.

Phase two of the project will focus on reconstruction, and it's set to begin on May 8th, weather permitting.

Consultants will meet with the Department of Water Resources on April 24th to go over further project details.
