Summary of streamflow, suspended-sediment concentrations, and grain sizes of sand-sized suspended sediment at gaging stations in the upper Yuba River watershed, California.

[See figure 1 for station locations. Sand-size material measured by the U.S. Geological Survey in Marina, California. ft³/s, cubic foot per second; mg/L, milligram per liter; mm, millimeter]

Map identifier	Station identifier	Date	Time	Streamflow (ft³/s)	Suspended-sediment concentration (mg/L)	Grain size percent finer than 2.0 mm	Grain size percent finer than 1.0 mm	Grain size percent finer than 0.5 mm	Grain size percent finer than 0.25 mm	Grain size percent finer than 0.125 mm	Grain size percent finer than 0.063 mm
