Lake Travis, the largest water storage reservoir in the region, holds over 300 billion gallons of water and experiences a natural process known as "turnover" twice a year. This phenomenon is driven by temperature changes. In the summer, long hot days warm the surface of the lake to over 80 degrees while the deeper water remains cool and stable. As colder weather arrives, the surface water cools, becomes denser, and sinks, pushing the deeper water upward. Wind further mixes the lake until the temperature is uniform throughout, officially marking the turnover.
This process brings noticeable changes. As bottom waters rise, decaying organic matter releases hydrogen sulfide gas, creating a distinct rotten smell at the surface. While unpleasant for people, the turnover provides nutrients that benefit fish populations. When warmer weather returns, surface water heats back up, pushing cooler water downward and restoring conditions favorable for swimming and recreation. This natural cycle helps maintain the health and balance of Lake Travis throughout the year.
