Oroville Dam Floodgates Opened, 1st Time Since February

21 Mar 2017, 5:06 pm

On Friday March 17th 2017, the Oroville Dam in California opened the the floodgates above the highly damaged spillway for the first time since the end of February .  


The Dam is releasing up to 50,000 cubic feet per second, dropping  Lake Oroville’s level by approximately four feet per day.  This latest release from the Oroville dam is to lower the lake level in order to provide sufficient storage for rain and snow-melt.  


The flow out of Lake Oroville was stopped at the end of February this year to allow workers to repair and stabilize the dam’s damaged spillway. Workers have removed 1.25 million cubic yards from the base of the spillway, with an expected 1.7 million cubic yards to be removed

Cracks in the remaining intact spillway were also cleaned and filled, concrete and the walls have been stabilized.

Erosion and cracks were found in and around the spillway in early February amid heavy rainstorms that brought the lake level up. Authorities evacuated the town in fears of the dam breaching. People were allowed home after several days.
