Perdido Pass

Perdido Pass, separating Alabama Point from Florida Point, is the mouth of the Perdido River. Perdido Pass forms a water passage that connects Perdido Bay with the Gulf of Mexico to the south, in the U.S. state of Alabama, 2 miles (3 km) west of the Alabama/Florida state line. A bridge spans Perdido Pass, connecting Alabama Point (western side) with Florida Point in Alabama (linked below). At the entrance into the Gulf, the 2 rock barriers, extending from the white beaches, are the west jetty & east jetty (see image). The surrounding area is heavily developed, with high-rise condominiums. However, there are nearby beach-front parks, with Gulf State Park on the eastern side of Perdido Pass.

Perdido Pass, extending between Florida Point and Alabama Point, is easily distinguished, from offshore, by the Alabama State Route 182 highway bridge in Orange Beach, Alabama, spanning the pass with two openings. The fixed span over Perdido Pass Channel has a clearance of 54 feet (16 m). The fixed span over Cotton Bayou Channel has a clearance of 41 feet (12 m). The dredged entrance channel leads from the Gulf through Perdido Pass to a fork at the highway bridge; thence into two channels, one leading north into Terry Cove and Johnson Cove and the other leading east into Bayou St. John. The entrance to the pass is protected by a jetty on the west and by a combination weir and jetty on the east; the top of the weir is submerged 6 inches (15 cm) at mean low tide. Numerous sunken wrecks are in the approach to the pass.

In October 2006, the controlling depth was 5.2 feet (1.6 m), reaching 8.2 ft (2.5 m) at mid-channel, in the entrance channel to the intersection of the east and west channels. From that area, thence 4.9 ft (1.5 m), reaching 8.3 ft deep (2.5 m) at mid-channel, in the west channel leading to Terry and Johnson Coves, thence 6.9 ft (2.1 m), reaching 7.4 ft deep (2.3 m) at mid-channel, in the east channel leading to Bayou St. John. The channels are well marked. A lighted whistle buoy off the entrance marks the approach.

The Intracoastal Waterway, in the lower part of Perdido Bay, is reached from Perdido Pass via a marked channel through Bayou St. John. In May 1982, shoaling to 6 feet (1.8 m) was reported in Bayou St. John, between day-beacons no. 6 and 8. An overhead power cable, with a clearance of 59 ft (18 m), crosses the channel leading to Terry Cove and Johnson Cove, about 0.4 miles (0.64 km) from the State Route 182 fixed bridge. Several small-craft facilities are in the coves and Cotton Bayou, on the W side of Perdido Pass 0.7 miles (1.1 km) above the entrance.
