Abstract: Water table management in the form of controlled-drainage and controlled-drainage/subirrigation is a feasible, yet under-utilized, practice in the Atlantic Coast flatwoods, the Ohio River Basin, the Lake Erie Drainage Basin, and the Lower Mississippi Valley. Agricultural expansion in these areas has potential due to current trends toward a dryer climate, salinity problems in other agricultural areas, projected population increases and/or available water resources. Current federal and state regulations do not preclude the development of WTM systems on most land that has the greatest potential for WTM technology. Economics is the major driving force for the future expansion of WTM due to the reduction in water related risks. WTM potential can not be realized without holistic-based research programs with combined environmental and economic concerns being addressed to anticipate, rather than create, problems.
