The park originated with the donation of land by Edward Habeeb and others for the creation of a state park at Rocky Gap. Initial state purchases began in 1963 with land acquisition continuing until 1966. In 1970, the Army Corps of Engineers dammed Rocky Gap Run to create Lake Habeeb. The park opened in 1974. ;Resort The Rocky Gap Resort and Golf Course was developed in 1998 by the MarylandEconomic Development Corporation, an agency created in 1984 that allows the State of Maryland to directly own or develop property for economic benefit. The facility opened in April 1998 at a cost of $53.9 million. The resort failed to sustain its early success, began posting losses, and became dependent on MEDCO subsidies to stay in operation. ;Casino In 2009, the state's initial effort to open a casino in the park failed when the only bidder, Empire Resorts, did not pay the required $4.5 million licensing fee. Empire's contingent bid was based on Maryland altering its 67 percent tax on casinos—one of the highest in the United States. In 2011, legislators lowered the state’s share of slots revenue at Rocky Gap from 67 percent to 50 percent. A casino license was awarded in April 2012 to a subsidiary of Lakes Entertainment of Minnetonka, Minnesota, who completed purchase of the existing resort, including the 200-room lakeside lodge, the Jack Nicklaus-designed 18-hole golf course, and other features, from the state in August 2012. The sale price was reported at less than $7 million. The renamed Rocky Gap Casino Resort opened on May 22, 2013, with 558 slot machinesand 10 live table games. In 2015, Rocky Gap Casino-Resort was acquired by Golden Entertainment when the company merged with Lakes Entertainment. The casino operates 665 gaming devices and 17 table games. The hotel has 198 rooms and suites.
