Plumas Lake is a master-planned exurb and census-designated place in Yuba County, California.

Plumas Lake was first conceived in 1993 as a means to guide development along the Feather and Bear Rivers.

[5] The old settlement was impacted by Gold rush-era hydraulic mining in the Yuba River watershed upstream.

Mine tailings wound up in the riverbeds and were then transported into the Sacramento Valley, where they accumulated in the river channels and reduced their conveyance capacities.

Flood risk has been a concern throughout Plumas Lake's development and many individuals and agencies were opposed to its construction.

[3] According to the United States Census Bureau, the CDP of Plumas Lake covers an area of 11.84 square miles (30.7 km2), all of it land.

Plumas Lake is in the southern tip of Yuba County near the confluence of the Feather and Bear Rivers.

The most popular definition is the census-designated place which includes land south of Algodon Road, north of Bear River, and some adjacent rural areas.

The largest definition is the Plumas Lake ZIP code area which includes land east of the Feather River, west of Forty Mile Road, and everything north of Bear River up to the new developments along Arboga Road.

Plumas Lake currently has 15+ parks (including Wheeler Ranch)[14] and a paved pedestrian/bike path called the Bear River Habitat Trail.

[15] Also nearby is the Plumas Lake Golf Club, Toyota Amphitheatre, and Hard Rock Hotel & Casino Sacramento at Fire Mountain.

Plumas Lake receives water, wastewater, park, and recreation services from the Olivehurst Public Utility District.
