Channel Cross-section Data for Powder River between Moorhead and Broadus, Montana from 1975 to 2016

This data release consist of 34 channel cross sections of Powder River measured from 1975 through 2016 along a 90-kilometer reach from Moorhead to Broadus, Montana. Most channel cross sections were measured annually from 1975 through 1998 and then intermittently through 2016. In 1978, after all cross sections had been established, there was a extreme flood with an approximate 50-year recurrence interval. Thus, the data represent the short- and long-term response to an extreme flood. The data are in 34 Excel files (one file for each channel cross section) containing worksheets corresponding to each channel cross-section survey (from 2 to about 40). Worksheets contain the basic survey data (dates, equipment, reference elevations, foresights, distances from reference pins, and elevations).
