Flood Frequency Data Collection, Alaska and Conterminous Basins in Canada

Data Download [Various] | AK Science Portal | Project Site | Date Range: 2022 - 2022

Estimates of the magnitude and frequency of floods are needed for engineering design of transportation and water-conveyance structures, flood-insurance studies, flood-plain management, and other water-resource purposes. In 2016, the U.S. Geological Survey estimated flood frequency and magnitude for selected streamgages in Alaska and conterminous basins in Canada and developed methods for estimating flood frequency and magnitude at ungaged streams (Curran and others, 2016). More current estimates of flood frequency are often needed for water-resource purposes, including estimating the annual exceedance probability of an observed flood peak.

Data sets included:

Flood Frequency Data and 2022 Observed Flood Probability for Two Streamgages in the Delta River Basin, Alaska, 1963-2022 Metadata
Flood Frequency Data for a Streamgage in the Hulahula River Basin, Alaska, 2011-2021 Metadata
Flood Frequency Data and 2020 Observed Flood Probability for Selected Streamgages in the Fortymile River Basin, Alaska, 1911-2020 Metadata
