Lake Travis is a large reservoir located northwest of Austin, TX, Texas, spanning over 30 miles in length and 4.5 miles in width. The lake was formed in 1942 following the construction of the Mansfield Dam on the Colorado River. As a result, the lake has become a popular destination for boating, fishing, swimming, and other water-based recreational activities.
The hydrology of Lake Travis is heavily influenced by rainfall in the region, which feeds into the Colorado River and ultimately the lake. Snowpack from the nearby Rocky Mountains also contributes to surface flow in the lake.
Agriculture is an important use of the surrounding land, with many ranches and farms producing crops such as corn, hay, and cotton. The lake also serves as a source of drinking water for nearby communities. In recent years, the lake has experienced periods of drought and low water levels due to decreased rainfall in the region.
