Abstract
Wildfires pose a significant risk to water resources due to alterations to hydrologic flow paths, increased export of eroded sediments, and the introduction of wildfire-produced organic matter. Black carbon, the condensed aromatic fraction of charcoal and burned biomass, can facilitate the transport of environmental pollutants, can promote the formation of toxic disinfection byproducts, and is a major contributor to the global carbon cycle. Due the unpredictable nature of wildfires, it is often difficult to examine organic matter—and associated black carbon—export immediately post-fire. This limits our understanding the catchment-specific and temporal changes in organic matter transport from fire-affected streams. The lack of data from “first-flush” events reduces the ability to model and mitigate perturbations of fire to aquatic systems. In August 2020, the SCU Lightning Complex Fires burned two paired, non-perennial watersheds (North Dark Canyon and South Dark Canyon) located at the Blue Oak Ranch Reserve in Mt. Hamilton, California. This dataset presents black carbon, organic carbon, total suspended solids and total dissolved nitrogen concentrations from samples taken from the first wet-up post-fire until dry down, capturing the "first-flush" and subsequent events immediately post-fire.
