Alluvial was sired by U.S. Racing Hall of Fame inductee Buckpasser, who in turn was sired by the 1953 United States Horse of the Year, Tom Fool, out of the Hill Prince mare Bayou. Alluvial was a half-sister, through Bayou, to the graded stakes race winning filly Batteur, who won the Santa Monica Handicap, Santa Margarita Handicap, Santa Maria Handicap, and Santa Barbara Handicap, as well as the New York Handicap.
Alluvial was unraced and is best known not for her racing success as a graded stakes race winner but for her success as a broodmare. She is the dam of Belmont Stakes winner Coastal, by Majestic Prince, and champion Slew o' Gold, by Seattle Slew.
On May 23, 1994, Alluvial died at Claiborne Farm due to the infirmities of old age.
