    Sediment and flow measurements were made during the course of 13 runoff seasons between 1982 and 1997 on a gravel-bed stream near Bondurant, Wyoming. The data for Little Granite Creek, compiled through the efforts of the U.S. Geological Survey and USDA Forest Service, is one of the most comprehensive databases on transport processes for an individual site available as of this writing. Bedload, moved by flows ranging from 0.05 times to nearly twice the bankfull discharge, was measured with an original Helley-Smith bedload sampler while wading, while suspended from a bridge, or from a temporary sampling platform. Samples of suspended load were collected using depth-integrating samplers. Laboratory analyses were conducted in accordance with standard U.S. Geological Survey methods. Hydraulic data were taken from summaries of discharge measurements maintained by the U.S. Geological Survey and by supplemental measurements made by Forest Service personnel in 1997. All data on rates of bedload transport, particle-size distribution of individual samples, suspended sediment load, measurements of hydraulic geometry, and channel surveys are presented in tables and graphs.
