Drink Tahoe Tap
Unlike many areas, we are lucky to have our tap water come from one of the freshest water sources in the country, Lake Tahoe. We are at the top of the water chain here in Tahoe with the water having only fallen from the sky in the form of rain or snow before it went through our water treatment plant and became your tap water. Use a refillable water bottle and Drink Tahoe Tap!

Dog Waste and Water Quality
Not only is the dog poop which gets left behind in our parks and on our beaches a nuisance and an eyesore, it can also be bad for the environment and a public health risk! Dog poop contains bacteria including Fecal Coliform and E. Coli which can get into water ways and pollute our drinking water. Many towns in the Tahoe basin get their drinking water straight from the lake, so remember, if "They Drop It, You Drink It."
UC Davis Tahoe Environmental Research Center
The UC Davis Tahoe Environmental Research Center annually produces the Tahoe: State of the Lake Report. The report summarizes data collected as part of the center’s ongoing, decades-long measurement programs, while also presenting research driven by important questions of the day. This includes how drought has impacted Tahoe’s forests, and the lake’s response to increasing levels of algae on the shoreline, climate change, and invasive species. It also takes a first look at what new technologies, including autonomous underwater vehicles, are finding in the deepest parts of the lake.
Aquatic Invasive Species, including Zebra and Quagga Mussels
One of the biggest threats to Lake Tahoe right now is the Zebra and Quagga Mussels.
