Online_Linkage: https://doi.org/10.5066/P9CG3DRR Description: Abstract: This table contains geographic information defining watersheds that were burned in large wildfires (greater than 100 square kilometers) that occurred in California or California-draining regions (i.e., upper Klamath watershed) between the years 1984 and 2021. Each wildfire was broken into tens to thousands of small watersheds, and each row of this table contains geographic information defining a single watershed. Purpose: We used these data to run the Water Erosion Prediction Project (WEPP) model using the Python module wepppy on all watersheds burned in all large wildfires from 1984 to 2021. From these data we created a statewide annual postfire sediment budget that is presented in the associated publication. These data can be used in combination with wepppy wrapper scripts that are available online (https://github.com/rogerlew/wepppy). Supplemental_Information: Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Note that although the metadata says the data are in UTM-10N projection, some of the data are in UTM-11N. Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 1984 Ending_Date: 2021 Currentness_Reference: Wildfires that occurred during this time period were part of our study.
