OROVILLE, Calif. - Those in the area should expect to hear the Oroville Dam spillway siren on Jan. 15.
The DWR said the 10-second siren will blare after 10 a.m. for several hours, following a "This is only a test," announcement.
Neighbors of the dam and those driving on Oro Dam Boulevard are expected to hear the siren, as well as those at the Diversion Pool, Spillway Boat Ramp area and Dam Crest/Oroville Dam Road.
The sirens are in place to notify people when water releases down the main spillway. They will be tested monthly, according to the DWR.
Officials say they believe testing will be done by late Wednesday afternoon.
