Summary

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected streamgages operated by the WY–MT WSC. This data release presents peak-flow frequency analyses for 11 selected streamgages in Jefferson County, Montana, that were based on methods described by Sando and McCarthy (2018).

Purpose

This dataset includes peak-flow frequency analyses and results for 11 selected streamgages in Jefferson County, Montana, based on data through water year 2017. Peak streamflow data used in the analyses are available from the U.S. Geological Survey (2018), and are available in the published data. Estimates of peak-flow magnitudes for 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent AEPs are reported. The procedures used for the peak-flow frequency analyses are documented in Sando and McCarthy (2018).
