Sierra Nevada Network lake monitoring project: Lakes throughout Sequoia, Kings Canyon, and Yosemite national parks are monitored to detect changes in water quality. Emerald Lake Watershed Study: Emerald Lake and the Tokopah Valley in Sequoia National Park have been the focus of sustained lake and watershed research since 1983. Knowledge gained through this research has transformed our understanding of how the thousands of lakes and watersheds in the Sierra Nevada are responding to global change.
