Lake Travis is the fifth lake down in the chain of Highland Lakes on the Colorado River in central Texas. Starting at Austin, Lake Travis winds its way northwest through the central Texas Hill Country for over 60 miles. It is the longest of the 7 Highland Lakes and is very popular for boating. At the widest point the lake is 4.5 miles wide. Austin is the largest city in the United States without a franchise in a major professional sports league. However, many Austinites enthusiastically support the University of Texas Longhorns sports programs.
