Periphyton blooms, however, signal changes that can degrade both water quality and a shoreline’s natural beauty.</p> October 06, 2025 - 9:06am Katherine E Kerlin /climate/news/lake-tahoe-algae-experiment-suggests-seasonal-shifts-ahead Wildfire Smoke Reached 99% of U.S. Lakes in 2019-2021 /climate/news/wildfire-smoke-reached-99-us-lakes-2019-2021 Where there's smoke, there's not always fire. Wildfire smoke drifted to nearly every lake in North America for at least one day per year from 2019 to 2021, found a UC Davis study.
