Changing Winters Are Impacting Lake Tahoe and Other Freshwater Ecosystems

By the end of the century, mountain lakes could be as early as 25 to 61 days earlier than they are today thanks to climate change, according to new research out of the Carnegie Institution for Science.

"We need to learn more about how this change in winter, whether from snowpack dropping on to a watershed or the loss of lake or stream-ice, may have lasting ramifications for what we might observe in the ice-free summer season," says one of the researchers in a press release.

Lake Tahoe, for example, doesn't typically have ice in the winter, but the smaller streams and lakes in the Tahoe basin and across the mountains of California rely on it as an important variable.

In another study, the researchers found that when ice on the lake melted sooner, the occupation of different lake habitats (nearshore versus deep water) changed for Brook Trout, as did their feeding behaviors.

"The science that is needed to conserve Lake Tahoe or the smaller streams and lakes in the Tahoe basin or California need to account for changes to winter processes," says the lead researcher. Read the Entire Article
