ABOUT LCRA LCRA is a conservation and reclamation district created by the Texas Legislature in 1934 to provide energy, water and community services to the people of Texas. LCRA cannot levy taxes, but gets its income to fund its operations from the sale of electricity, water and other services. LCRA sells wholesale electricity to city-owned utilities and cooperatives that serve more than 1 million people in Texas. LCRA also sells stored water; develops and operates water and wastewater utilities; manages the lower Colorado River; protects water quality; owns and operates parks; promotes conservation of soil, water and energy; and offers economic and community development assistance to rural communities.
