2022 McKinney rain-on-wildfire study area on the main-stem Klamath River, California. The map shows burned areas from historical wildfires between 2013 to 2022, burned areas for the 2022 McKinney Fire and 2022 Yeti Fire, major tributaries, four dams removed in 2023 and 2024, and three monitoring stations. River distances, measured upstream from the river mouth, are 282 km to the confluence of Humbug Creek, 272 km to the confluence of Vesa Creek, 211 km to the Seiad station (USGS station number 11520500), 96 km to the Orleans station (USGS station number 11523000), and 13 km to the Klamath station (USGS station number 11530500). Photos taken the week after the rain-on-wildfire event show (a) a post-fire debris flow (PFDF) scar in the headwaters of Vesa Creek58, (b) a debris fan at the confluence of Vesa Creek with the main-stem Klamath River58, (c) active fire and fish kill (Karuk Tribe), and (d) and sample of fire-scar material in transport at the Klamath station (Public Domain).
