After three years of busts, 2023 was a boom year for snow in the Sierra Nevada. Data provided by INSTAARs Noah Molotch, Leanne Lestak, and Kehan Yang provide a detailed picture of snowpack across the range and at different elevations, which helps the California Department of Water Resources and other water managers better forecast snowmelt in California.

AVÃûʪers find that heavy snowmelt plus usually warm temperatures amped up Oroville Dam incident

July 23, 2020

In February 2017, failures in the spillways of Oroville Dam forced the evacuation of 188,000 people and caused $1 billion in damage repairs. According to scientists, including INSTAARs Keith Musselman, Leanne Lestak, and Noah Molotch, a warmer climate might create more dangerous events like this.
