Shoreline algal blooms are rapidly approaching crisis condition at Lake Tahoe. The blooms degrade water quality, cover large areas of beach with mats of decomposing algae, and in Fall 2021 caused the first toxicity-related beach closure. 2022 conditions were even more dire.
TERC’s nearshore algal monitoring program uses helicopter surveys to record the entire shoreline of the lake at monthly intervals through the prime growing season to discover and track algal blooms. This research serves as a warning system, to alert the public and agencies to potentially dangerous situations, and guides clean-up crews to where they are most needed.
Help the TERC algal research team to maintain, expand and mitigate to preserve the beauty of Lake Tahoe.
