The Lower Colorado River Authority was created in 1934 by the Texas Legislature as a conservation and reclamation district with no taxing authority and operates solely on utility revenues and fees generated from supplying energy, water and community services.  LCRA supplies low-cost electricity for Central Texas, manages water supplies and floods in the lower Colorado River basin, develops water and wastewater utilities, provides public parks, and supports community and economic development  including managing the Highland Lakes.   Goals include providing low-cost utility services and to help ensure the protection and constructive use of the area's natural resources.  The Highland Lakes chain consists of 7 lakes starting at Lake Buchanan and culminating in Lady Bird Johnson Lake in Austin.
