For over 50 years, researchers with the UC Davis Tahoe Environmental Research Center (TERC) have been carefully observing the waters of Lake Tahoe. This week, the annual “State of the Lake” report was released. According to UC Davis TERC director Geoffrey Schladow, 2021 data shows some major changes that hadn’t been observed to this point. One of the most notable is a drop in the Mysis shrimp population. This non-native plankton species was introduced into the lake in the 1960s.
