Rollover Pass (Gilchrist, Galveston County, Texas) also called Rollover Fish Pass is part of a low-elevation area and was subject to overflow during high tides or storms. A man-made strait was cut through private property on the Bolivar Peninsula and linked the Gulf of Mexico with Rollover Bay and East Bay on the upper Texas coast in eastern Galveston County. Located on property which was owned by the Gulf Coast Rod, Reel and Gun Club and managed by the Gilchrist Community Association, the Pass was widened to allow more water flow in 1955 by the Texas Game and Fish Commission when it was granted an easement by the property owners. The intent was to increase bay water salinity, promote growth of submerged vegetation, and help marine fish to and from spawning and feeding areas in the bay.
