Perdido

Perdido, a small river and bay, which form the W. boundary of Florida, separating Escambia co. in that state from Baldwin co. in Alabama. Perdido bay is more properly a lake, into which the river expands near its mouth. It is landlocked, and its outlet into the gulf of Mexico is so small, and enters at so acute an angle with the line of coast, as to be almost undistinguishable from the sea, whence the river probably derived its Spanish name Perdido, or " lost." There are generally but 4 or 5 ft. of water on the bar at its mouth. The Perdido was the boundary between the French and Spanish colonies of Louisiana.and Florida.
