From its rolling hills and rich delta farmland to its 25 lakes and 320 miles of shoreline, Lee County is one of East Arkansas’ greatest treasures. Agricultural processing and manufacturing have been the cornerstone of economic growth in Lee County and county seat Marianna, which boasts more than 40 available acres of industrial park. The Lon Mann Cotton Research Station in Marianna is a leader of statewide soil testing and research of cotton, soybeans, wheat, grain and corn. Lee County is also home to a national forest and Arkansas’ most recently opened state park.
