In the immediate aftermath of the SR530 Landslide, the USGS supported first responders and decision-makers as a key member of the collaborative effort to monitor the stability of the landslide deposit and the associated impoundment of the North Fork Stillaguamish River during rescue operations. With the initial disaster response now over, longer-term questions have arisen regarding the stability of the newly incised channel and the fate of sediment eroded from the deposit.

Building upon the efforts and instrumentation deployed during the initial response, the USGS is actively monitoring the evolution of the new channel and the volumes of sediment transported by the river at locations upstream and downstream of the landslide. These data are a critical part of recognizing and responding to potential hazards to the newly reconstructed stretches of Highway 530 and downstream bridges, and for understanding changing flood hazards both upstream and downstream of the slide.
