Determining the single-season high school rushing leader for the state of Louisiana is difficult because comprehensive, consistently maintained statewide records across all classifications and schools aren't readily available in a single, publicly accessible database. High school sports record-keeping varies significantly by state and often relies on news reports and individual school documentation.
To find this information, you would likely need to research individual high school football news archives, Louisiana High School Athletic Association (LHSAA) records (if they maintain such a comprehensive statistic), and potentially contact sports journalists specializing in Louisiana high school football.
