Knoxville Municipal Airport: Aviation in Marion County and the Des Moines River Valley
Marion County in south-central Iowa is defined by the Des Moines River flowing north to south through the county's eastern portion, with Knoxville — the county seat — situated on the upland above the river valley. Knoxville Municipal Airport serves the community with a general aviation facility positioned on the rolling Southern Iowa Drift Plain terrain, providing aviation access for this agricultural county that hosts Lake Red Rock, Iowa's largest lake, created by the Army Corps of Engineers' Red Rock Dam on the Des Moines River. Lake Red Rock's 19,000-acre surface attracts recreational boaters, anglers, and campers who drive through Marion County from across Iowa, and private pilots occasionally fly into Knoxville Municipal for lake access. Knoxville is also famous for its sprint car and dirt track racing heritage at the Knoxville Raceway, which hosts the prestigious annual Knoxville Nationals sprint car race drawing top drivers and aviation visitors from across the country. This motorsports heritage creates a seasonal aviation spike during Nationals week in August.
Marion County's proximity to Des Moines International Airport (DSM) — roughly 40 miles northwest via Highway 163 and I-80 — gives the county excellent commercial aviation access. The county's agricultural base of corn, soybeans, and beef cattle is serviced by aerial application operators who work around the Des Moines River bottomland fog that characterizes autumn flying conditions in this part of central Iowa. Pella — home to Pella Corporation window manufacturing and Central College — adds corporate and educational aviation activity to the county's aviation profile.
