Lake Buchanan was the first lake completed in the Highland Lakes chain and was created primarily to store water and supply hydroelectricity. It was created with the construction of the 2-mile long Buchanan Dam and is considered the longest multiple-arch dam in the nation. It is the second largest lake in the chain, it is about 30 miles long and almost 5 miles wide at the widest point. It's almost like looking at an ocean scene at the wide part of the lake and is a great lake for fishing and boating.
Lake Buchanan is managed by the Lower Colorado River Authority (LCRA) which was created in 1934 as a conservation and reclamation district, supplying water and electricity to neighboring areas. LCRA manages the entire Highland Lakes chain of lakes which start at Lake Buchanan and culminate in Lake Austin.
