Flood Frequency Data for a Streamgage in the Hulahula River Basin, Alaska, 2011–2021

This data release provides the source data and results of a flood frequency analysis for a streamgage in the Hulahula River Basin, Alaska. Data are provided for one streamgage that had at least 10 years of peak-flow record. The data include streamgage information, PeakFQ input (.txt and .PSF files) PeakFQ output (.PRT, .EXP, and .JPEG files), flood frequency parameters, flood frequency estimates for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities. These data were intended to support investigations of streamflow in the Hulahula River Basin.
