This report has been superseded by OF 2004–1085
This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code.
This report is a compilation of peak-discharge and event-volume data measured from basins which have been burned by wildfire in the western U.S. Each point on the map represents a location for which measurements of post-fire runoff (either debris flow or flood) have been published or reported by personal communication. This database was created as a tool for land managers who need measurements of post-wildfire runoff events in order to make appropriate mitigation decisions.
You may click on the locations on the map to learn more about each runoff event. The information is organized in the database by state, and includes the location and year of the fire, measures of basin area and relief ratio, the percent of the basin burned by fire, any reported rainfall information, and the reference for each event. When not reported in the original reference, we measured the basin area and relief ratio from 7.5' topographic quadrangle maps. The relief ratio was calculated as the maximum relief from basin mouth to the drainage divide divided by the length of the longest stream channel extended to the drainage divide. We also list the flow process (debris flow, mudflow, flood, etc) as reported by the authors. The bibliography can be linked by clicking on the reference author's name or source heading in the table. You may also access the database or bibliography directly through these links.
We plan to update the database periodically as more information becomes available. If you have data you would like to contribute, contact Sue Cannon at cannon@usgs.gov.
