Wildfire And Water Security: Post-Fire Erosion And Sedimentation Threaten Utah's Reservoirs, Quinn Olpin, Kendall Becker, Scott Hotaling, Aish Chandrasekaran, Patrick Belmont

All Current Publications

As an arid state with limited water, Utah relies heavily on reservoir storage to maintain its water supply throughout the year. This vital water storage, however, is increasingly at risk due to contemporary wildfires. Wildfires pose a risk to water storage because after vegetation burns, erosion typically increases. Eroded soil can be carried by rivers and deposited into reservoirs where it accumulates as sediment, reduces water storage capacity, clogs dam outlets, and degrades water quality. Identifying which watersheds are most vital to maintaining Utah’s water supply, are most threatened by wildfires, and are most prone to high levels of post-fire …
