UPDATE 10 a.m. FRIDAY: In a Facebook post Thursday night, the National Weather Service's Sacramento office said the dam was not at risk of "imminent failure" and a flood watch was set to be cancelled.
There is a flood watch in effect until midnight Thursday for a private earthen dam in Yuba County along Little Dry Creek.
Yuba County and local officials have reported the possibility of the dam's failure.
Several homes in the area have been notified by local law enforcement of the potential dam failure. Flooding would occur in rural areas south of the dam and possibly toward Spring Valley Road in Yuba County.
