Continuous 15 min streamflow and water-quality observations showing unprecedented and acute water-quality impairments captured at the Seiad station, within a 95 km fish kill zone and located 211 km upstream from the Pacific Ocean and 71 km downstream from the Humbug Creek confluence along the main-stem Klamath River, California. Time-series graphs show streamflow, turbidity, specific conductance (SC), dissolved oxygen (O2), pH, and water temperature observations from July to September and show the 2022 data collected before, during, and after the McKinney rain-on-wildfire event in the context of historical data spanning 2012 to 2021, with turbidity data spanning 2018 to 2021. The Seiad station description is in (Table 1), the Seiad station location is shown in (Figs. 1, 2), and the fish kill zone is shown in (Fig. 1).
