The site was purchased in 1923 and Marine Stadium was created two years laters when the Alamitos Bay was dredged to only 1.5 km (0.93 mi) in length. An additional 0.5 km (0.31 mi) was dredged by 1932 in time for the Olympics in LA. Turf replaced the temporary grandstands in 1997. The following year, the venue expanded to accommodate new teen and disabled rowing programs. Permanent restrooms replaced temporary ones in 2009.
