“…During hydrologic events, OC and associated BC are mobilized from the burned landscape to lower reaches of the watershed and downstream waterbodies (e.g., lakes and oceans), thereby affecting downstream water quality (Shakesby et al 2016). The increased mobilization of sediment, OC, and BC post-fire can also pose challenges for downstream water resources and treatment facilities (Cawley et al 2017;Robinne et al 2018Robinne et al , 2021Hohner et al 2019;Chen et al 2022).…”

Coastal mountain rivers export disproportionately high quantities of terrestrial organic carbon (OC) directly to the ocean, feeding microbial communities and altering coastal ecology. To better predict and mitigate the effects of wildfires on aquatic ecosystems and resources, we must evaluate the relationships between fire, hydrology, and carbon export, particularly in the fire‐prone western United States. This study examined the spatiotemporal export of particulate and dissolved OC (POC and DOC, respectively) and particulate and dissolved black carbon (PBC and DBC, respectively) from five coastal mountain watersheds following the 2020 CZU Lightning Complex Fires (California, USA). Despite high variability in watershed burn extent (20–98%), annual POC, DOC, PBC, and DBC concentrations remained relatively stable among the different watersheds. Instead, they correlated significantly with watershed discharge. Our findings indicate that hydrology, rather than burn extent, is a primary driver of post‐fire carbon export in coastal mountain watersheds.
