| Summary: | This data package documents selected special conditions affecting the magnitude of peak flows at streamgages in Alaska. The data consist of a table of special conditions for selected peak flows and a table of data sources. This dataset resolves ambiguity introduced by historical variations in USGS National Water Information System (NWIS; https://doi.org/10.5066/F7P55KJN) peak-flow code assignment practices or inherent in defining multiple possible conditions for a single code. For peak flows assigned a code 3 or 9 in the NWIS peak-flow database, the special conditions forming the basis for code assignment were (1) snowmelt or (2) a sudden release of water. Sudden releases of water included glacier dammed lake outburst, glacier and debris dammed lake outburst, sediment dammed lake outburst, mass failure/lake outburst, landslide debris dam breakup, beaver dam breakup, natural flow diversion, or subsidence from detonation subcategories. Data sources used to verify the basis for the codes included reports, ... |
