Summary
The USGS Wyoming-Montana Water Science Center (WY–MT WSC) recently 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. In association with the report, this data release presents peak-flow frequency analyses for 14 selected streamgages in the Beaverhead River and Clark Fork Basins that were based on methods described by Sando and McCarthy (2018). The results are presented in three child items: a child item containing [...]

In association with the report, this data release presents peak-flow frequency analyses for 14 selected streamgages in the Beaverhead River and Clark Fork Basins that were based on methods described by Sando and McCarthy (2018).
The results are presented in three child items: a child item containing the results excel spreadsheet, a child item containing the peak flow specification file, and a child item containing the WATSTORE file.

Sando, S.K., and McCarthy, P.M., 2018, Methods for peak-flow frequency analysis and reporting for streamgages in or near Montana based on data through water year 2015: U.S. Geological Survey Scientific Investigations Report 2018–5046, 39 p., https://doi.org/10.3133/sir20185046.
This dataset includes peak-flow frequency analyses and results for 14 selected streamgages in the Beaverhead River and Clark Fork Basins, Montana, based on data through water year 2016. 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).
