With temperatures spiking across California this week, now is a great time to reserve your spot on our Headwaters Tour July 24-25 when we’ll explore the role of the Sierra Nevada snowpack in the state’s water supply and how heatwaves can accelerate snowmelt. The state’s critical ‘frozen reservoir’ was slightly above average at the end of the 2024 snow survey season, following an epic snowpack in 2023 that prompted widespread flooding and the resurrection of Tulare Lake. During the July tour, we’ll also learn how snowpack is measured and translated into forecasts of California’s water supply for the year. … The 2-day, 1-night tour with an overnight in Lake Tahoe travels up the Sierra foothills and into the mountains within the American River and Yuba River watersheds. Meadow restoration, climate change, wildfire impact and more will be discussed as we pass through Eldorado and Tahoe national forests.
