The photo shows the Klamath River following the 2022 McKinney Fire, with burned areas visible along the distant ridgeline and a debris fan in the foreground near the confluence of Little Humbug Creek and the Klamath River. The photo documents sediment and debris deposited from burned landscapes into the river corridor following wildfire and storm runoff.

Methods of addressing problems of subsidence and increasing carbon storage at White Slough include: 1] reuse of sediment to fill subsided areas and restore elevations that support marsh vegetation (left), and 2] breaching historic dikes in order to restore tidal hydrology (right).

Keswick Reservoir, on the Sacramento River near Redding, receives both water and contaminants via outflow from an upstream dam. Information is needed on dilution rates and how these vary with hydrological/meteorological forcing and reservoir management.
