This lake was the only natural lake in Texas until it was artificially dammed in the early 1900s when oil was found and for flood control in 1914. A new dam replaced the old one in 1971. From its freshwater marshes, backwater swamps, and majestic moss-festooned bald cypress, Caddo Lake provided plenty of inspiration for the Civilian Conservation Corps in the 1930s who constructed landscape-friendly structures, including the quaint cabins still in use today. Activities enjoyed by visitors include camping, birding, hiking, paddling trails, picnicking, nature study, fishing and boating.
