30 Facts About Lake Travis Water Level

Understanding Lake Travis

Lake Travis, a reservoir on the Colorado River in central Texas, is a popular spot for boating, fishing, and swimming. Its water level can fluctuate significantly due to various factors. Here are some intriguing facts about Lake Travis water levels.

1. Lake Travis was created in 1942 to manage flood control and water supply. The Mansfield Dam, originally called Marshall Ford Dam, was built to create the reservoir.

2. The lake spans 63.75 miles in length, making it one of the largest lakes in Texas. Its vast size contributes to the significant changes in water levels.

3. Lake Travis has a maximum depth of 210 feet. This depth can vary greatly depending on rainfall and water usage.

4. The lake's full pool elevation is 681 feet above mean sea level (msl). This is the level at which the lake is considered full.

5. During droughts, the water level can drop significantly. In 2011, the lake reached a historic low of 618 feet msl due to severe drought conditions.

6. Flooding can cause the water level to rise dramatically. In 2018, heavy rains caused the lake to rise to 704 feet msl, well above its full pool elevation.

7. The Lower Colorado River Authority (LCRA) manages the water levels. They monitor and adjust the levels to balance flood control, water supply, and recreational use.

8. Lake Travis is part of the Highland Lakes chain. This chain includes six lakes that are all managed by the LCRA.

9. The lake's water level affects local wildlife. Fluctuations can impact fish populations and the habitats of various bird species.

10. Recreational activities depend on water levels. Boating, fishing, and swimming conditions can change based on the lake's current state.

Historical Water Levels

Lake Travis has seen many changes in its water levels over the years. These historical fluctuations provide insight into the lake's behavior and management.

11. In 1951, the lake reached its highest recorded level of 710.4 feet msl. This was due to heavy rainfall and flooding.

12. The 1980s saw significant droughts that caused the lake to drop below 630 feet msl multiple times.

13. In 2007, the lake experienced a rapid rise. Heavy rains caused the water level to increase by over 20 feet in just a few days.

14. The 2011 drought was one of the worst in Texas history. Lake Travis dropped to 618 feet msl, its lowest level since the lake was created.

15. In 2015, the lake recovered from drought conditions. Heavy rains brought the water level back up to 681 feet msl.

16. The 2018 floods were a significant event. The lake rose to 704 feet msl, causing widespread flooding and damage.

17. Historical data helps predict future trends. By studying past water levels, the LCRA can better manage the lake's future.

Factors Influencing Water Levels

Several factors contribute to the fluctuations in Lake Travis water levels. Understanding these can help explain why the lake changes so much.

18. Rainfall is the primary factor. Heavy rains can cause the lake to rise quickly, while droughts can cause it to drop.

19. Water usage impacts levels. The lake provides water for millions of people, and high usage can lower the water level.

20. Evaporation plays a role. During hot Texas summers, significant amounts of water can evaporate from the lake.

21. Inflow from upstream reservoirs affects levels. Water released from other reservoirs in the Highland Lakes chain can raise Lake Travis.

22. Outflow through the Mansfield Dam controls levels. Water released from the dam can lower the lake to manage flood risks.

23. Seasonal changes influence levels. Spring and fall typically see higher water levels due to increased rainfall.

24. Climate change may impact future levels. Changes in weather patterns could lead to more extreme fluctuations in the future.

Impact on Local Communities

The water levels of Lake Travis have a significant impact on the surrounding communities. These effects can be both positive and negative.

25. Property values can fluctuate with water levels. Homes near the lake can see their values rise and fall based on the lake's condition.

26. Tourism is affected by water levels. High water levels attract more visitors, boosting the local economy.

27. Low water levels can harm businesses. Marinas, restaurants, and other businesses that rely on the lake can suffer during droughts.

28. Flooding can cause significant damage. High water levels can lead to property damage and costly repairs.

29. Water quality is influenced by levels. Low levels can concentrate pollutants, while high levels can dilute them.

30. Community planning relies on water level data. Local governments use historical and current data to plan for future water needs and flood risks.
