Summary of streamflow and suspended-sediment measurements for four sites in the Upper Yuba River watershed, California, during water years 2001, 2002, and 2003.

[See figure 1 for station locations. Latitude and longitude are referenced to the North American Datum of 1927 (NAD 27). Elevation is referenced to the National Geodetic Vertical Datum of 1929 (NGVD 29). EDI, equal-discharge interval; N, number of samples. mi², square miles; ft, feet; ft³/s, cubic feet per second. —, gage discontinued because of poor rating]
