Summary:
- Extreme weather patterns, such as droughts and heavy rainfall, are affecting the clarity and light levels in Lake Tahoe, a large freshwater lake in California.
- Droughts can lead to less runoff and sediment entering the lake, which can increase water clarity. However, heavy rainfall events can also increase sediment and nutrient levels, reducing water clarity.
- These changes in water clarity and light levels can impact the delicate ecosystem of Lake Tahoe, affecting the plants and animals that rely on the lake's unique environment.
