Contemporary fire history metrics for the conterminous United States (1984-2023) (ver. 3.0, April 2024) Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey's Landsat Burned Area product was used to identify burned area across CONUS over a 40-year period (1984-2023). The Landsat BA product was consolidated into a suite of annual BA products, which in-turn were used to calculate a series of contemporary fire history metrics (30 m resolution). Fire history metrics included: (1) fire frequency (FRQ), (2) time since last burn (TSLB) and (3) year of last burn (YLB), (4) longest fire-free interval (LFFI), and (5) average fire interval length (FIL). All metrics...

There are 4 separate datasets associated with this Data Release: Water quality data from major Colorado River tributary monitoring sites in and near Grand Canyon from 2015 through 2022. Sediment quality data from the Colorado River and major tributary monitoring sites in and near Grand Canyon from 2015 through 2022. Water quality results from spring and stream sites in Grand Canyon that were sampled by U.S. National Park Service personnel in 2016 and 2017. Time series water quality results from select spring sites in Grand Canyon that were sampled using a Minisipper autosampler. Filtered...

Surveys were conducted within occupied Lahontan cutthroat trout habitat, as designated by the U.S. Fish and Wildlife Service. Data represent reach-based surveys conducted in accordance with the Lahontan cutthroat trout habitat status assessment (LCTHSA) protocol (USGS). LCTHSA uses a probabalistic sampling design (i.e., Generalized Random Tessellation Stratified), standardized collection of habitat attributes, electronic data capture and management, and integration with remote sensing and geospatially-derived data products. Data were collected and managed by the U.S. Geological Survey and U.S. Fish...
