The Lower Arkansas Valley Drainage System Study

 This study concerns the future use of aging subsurface and surface  drainage systems in the Lower Arkansas Valley, Colorado. The Lower  Arkansas Valley subsurface drainage systems are 90 years old. Tile  drains and associated manholes, collectors, and wasteways are in a  deteriorated condition. This contributes to saline high water tables and  crop production problems.

 This project is generating information that will assist and benefit 25  small drainage districts in the Lower Arkansas Valley. It involves  conducting a major inventory and estimation of costs and benefits  associated with rehabilitating approximately 200 miles of subsurface tile  drains and 107 miles of surface drainage wasteways in the lower valley  (i.e., Crowley, Otero, Bent and Prowers counties).
