Glen Canyon Dam were closed. By the summer of 1972 the lake, fed by the Colorado River, 

 was nearly 400 feet deep at the dam and extended 289 miles upstream with over 1,800 

 miles of serpentine finger shoreline. During 1972 over 770,000 tourists visited the Lake 

 Powell recreation area. Many of these visitors took advantage of the marina facilities at 

 Wahweap. 



Wahweap Lodge and Marina north of Page, Arizona, is a total recreation complex 

 operated by Canyon Tours, Inc., under exclusive contract to the U.S. National Park Service. 

 The marina has an ultimate capacity of 300 slips and is located near the lodge parking lot 

 (Fig. 174). Several unique design features are incorporated into this marina. The dock is a 

 floating system anchored by cable, dictated by the great deptli of water and the annual 

 water level fluctuation of about 18 feet. The original installation consisted of 32 slips of 

 wood and polystyrene construction, but the newer docks are of steel construction. The 

 flotation units consist of steel plates rolled into 42-inch-diameter by 8-foot-long tubes with 

 sealed ends. The tubes are bolted together with steel straps and angle iron braces, which act 

 as supports for the metal framework in which the 2- by 4-foot steel deck panels rest. The 

 main walks are constructed in 400-foot lengths interconnected with hinge-and-swivel joints. 

 The finger piers are also connected to the main walks with hinge-and-swivel joints to 

 accommodate wave action without overstressing the system. 



The floating slip is moored in place by a web network under the docks to which are 

 attached 1.125-inch-diameter wire rope mooring lines leading to 5,000-pound bottom 

 anchors. The system is adjusted laterally as the water surface fluctuates by hand winches; 

 land access is achieved by adding or subtracting floating walkway sections. 



The berths are protected by a unique floating breakwater designed by the U.S. National 

 Park Service. The breakwater is constructed of cellular concrete containing polystyrene 

 flotation elements. Manufactured sections are about 8 feet wide and 10 feet high. These 

 sections float with a freeboard of about 3 feet and a keel depth of 7 feet. The sections are 

 interconnected with heavy chain, and the entire breakwater is moored in position with 

 1-inch-diameter wire rope lines attached to 20 (U.S. Navy -type) 1,500-pound anchors. A 

 system of hand winches adjusts to the varying lake levels. The breakwater is at the lower left 

 in Figure 175. 



Marina occupancy is averaging 70 percent during the winter months and exceeds capacity 

 during the summer season. During the 1972 summer season, 210 private power craft, 

 8 private sailboats, 12 commercial tour boats, and 105 rental boats were berthed at the 

 marina. Slip-rental rates were $1.75 per foot per month, or $2.50 to $3.50 per day when 

 available. The marina manager estimates the major activities of the patrons to be cruising 

 (40 percent), fishing (35 percent), and skiing (25 percent). 



Electrical power (120 volts) for lighting is supplied to the docks and the charge is 

 included in the shp-rental fee. The dock lighting is a high-level system. Water is supplied 

 free, there is a public address system to the docks, and four phones are strategically located 

 along the piers. The marina has a sanitary holding tank, purapout facilities, and daily trash 

 collection.
