San Luis Pass is a strait of water at the south-western end of Galveston Island off the shores of the U.S. state of Texas. It connects the sheltered waters of West Bay to the open Gulf of Mexico. Swimmers and fishermen have been killed in the Pass' treacherous waters, largely due to murky water, uncharted drop-offs, and fast moving currents. The San Luis Pass-Vacek Toll Bridge spans San Luis Pass into Brazoria County.CharacteristicsTide levels can vary by almost 2 feet in height, although the tidal effects seem more pronounced along straits than other barrier island zones. Water current dangers are prominent up to about one mile away from the pass along either island. A high amount of drownings occur in the vicinity of the San Luis Pass compared to other areas off of nearby beaches. Until June 2013, about 10 people drowned near San Luis pass on the Galveston side since 2001, and of those about 6 drowned there since 2007. The depth of the pass varies to up to 40 feet deep.Tides cause daily variations in topography, and occasionally, storms more drastically change the topography of the pass.Fishing and recreationPier fishing on the San Luis Pass Pier was a favorite for visitors and locals alike for many years, however the beach and pier were wiped out during Hurricane Ike in 2008, and it was not rebuilt. The pass is also home to bank fishermen who often travel many miles to take advantage of the excellent redfish population from June thru October.
