is water pollution. Pollution has been an increasing issue for the lake, which is known for its crystal-clear waters. Pollution comes from numerous sources, including urban runoff from streets and yards, watercraft activities, and atmospheric deposition of chemicals and particulates. These activities disturb the delicate balance of the lake’s healthy ecosystems. As water pollution increases, it leads to an increase in sediment in the lake, which clouds the water and diminishes clarity and prevents sunlight from reaching deep enough for underwater photosynthesis, which is essential for maintaining the lake’s food web. Reducing the impacts of pollution on Lake Tahoe requires efforts from both local and regional agencies.
