Fort Smith is located in the Arkansas River Valley, a region with a humid subtropical climate and frequent heavy rainfall events. Stormwater runoff from industrial and urban areas can carry pollutants such as oil, grease, heavy metals, and sediments into local waterways. The outfall discharges into the Arkansas River watershed, which is a major tributary of the Mississippi River. Effective stormwater management is essential to prevent water quality degradation and to comply with the Clean Water Act's goals of restoring and maintaining the chemical, physical, and biological integrity of the nation's waters.
