Wearing snowshoes and aviator sunglasses, Gov. Gavin Newsom stood in a field near Lake Tahoe recently and listened as an engineer from the Department of Water Resources announced the results of California’s April snow survey, which is conducted every year when snow depths in the Sierra Nevada reach their maximum.
The combination of these factors means that mountain snowpack plays a crucial role in regional hydrology, since it acts as a sort of natural reservoir that stores substantial amounts of water during the winter and spring and disburses it over the course of the summer. With the help of computer models, we can begin to disentangle the effects climate change will have on California’s snowpack over the coming decades.
