Milton is a small 12-acre instream diversion dam and lake on the Middle Fork Yuba River. Nearby towns are Sierra City (4.09 miles) and Graniteville (10.06 miles).

The dam was originally constructed in 1926 to build head and push water into the Milton-Bowman Conduit. 

Later, it was part of the Yuba–Bear Hydroelectric Project, constructed in 1964-65.  The Project is the cornerstone of the District's operations, providing vital benefits to customers, the community, and the environment. 

Milton is downstream of Jackson Meadows and includes the Milton Main Diversion Dam, Milton South Diversion Dam, the Milton Diversion Dam Spillway, and the Milton Diversion Impoundment. Standing 195 feet high and 1,530 feet in length, the dam is an earth-rock fill dam. The reservoir has a capacity of 69,205 acre-feet. The deepest part of the lake is on the west end near the dam.  

Environmental flow requirements to the Middle Yuba are currently 3 cubic feet per second.

Recreation: The lake supports dispersed camping and fishing. Depending on the month and water year type, Milton is known for trophy trout fishing (catch and release). It is part of the wild trout program of California's Department of Fish and Wildlife .

No motors are allowed on this lake, and there is a zero-trout limit and no bait allowed. The closest developed campgrounds are at Jackson Meadow Reservoir to the south.

Milton is located in the Tahoe National Forest.
