These data were collected to measure possible debris flows into the lake during the 2018-2019 rainy season following the July-August 2018 Carr fire that burned vegetation around the entire lake. Post-fire hillslope sediment yields are commonly substantially greater than pre-fire yields, but the degree to which they increase can vary substantially. Effects of wildfire on sediment yield have important implications for hazards (debris-flow risk), ecosystem disturbance and recovery, and downstream water...

The original survey collected 130 km of data with a 14-cubic inch sleeve-gun (airgun) source, a 24-channel streamer, and 3.125 m shot spacing. Reprocessed profiles show increased data resolution, with data recorded to 750 ms two-way-travel-time, and interpretable data down to about 400 m.
