Entergy Arkansas' Bobby Pharr has, arguably, the best office in the whole company. As manager of the lakes, Pharr's work space overlooks picturesque Lake Catherine, the body of water that was formed about 70 years ago when company founder Harvey Couch built Remmel Dam on the Ouachita River near Hot Springs. At the time, the electricity generated at Remmel Dam was the biggest power source the company had going. Today, it's still cranking out clean electricity, but it supplies only a small fraction of what is consumed these days by Entergy customers.
