Environmental Change in the Lake Tahoe Basin
Discover the science behind Lake Tahoe’s changing environment in this multidisciplinary book published by the University of Nevada Press. Written for a general audience, it brings together decades of research to tell the story of Tahoe’s past, present, and future.
This site offers supplementary materials to complement the book, including data, figures, and additional resources for readers who want to dive deeper.

OSM 1-1 The relative importance of dissolved and particulate matter in scattering and absorption of light in the Lake is shown. Note that inorganic material is the largest contributor to scattering of light, but not to its adsorption, where phytoplankton dominate.

OSM 4-1 Average annual Tmax and Tmin, averaged across the Basin and four ESMs, for historic (1950-2005) and future (2006-2100), RCP 4.5. Data smoothed with a three- year running average.

OSM 4-2 Projected future percent of precipitation falling as snow in the Tahoe Basin, average of four ESMs, with RCP 4.5

OSM 4-3 Shows the downward trend in maximum annual snowpack Snow Water Equivalent (SWE, the depth of water stored in the pack) for the basin-wide modeled future under RCP 4.5 plotted together with the modeled historic snowpack.

OSM 11-3 Curlyleaf Pondweed (Potamogeton crispus), native to Europe, is a widespread invasive submersed plant that is found in all contiguous US states. It was first noted in the Tahoe Keys channels in 2003 (see OSM 11-4) and it's fast spread within the Tahoe Keys was documented over the course of 3 years.

OSM 11-4 Eurasian watermilfoil, a nonnative submersed aquatic plant from Eurasia, was first identified in the Tahoe Keys in 1995 (Anderson and Spencer 1996). Since then, new infestations have been documented every few years, demonstrating its continued spread along the Lake Tahoe shoreline.
