Abstract Over the last two centuries, agricultural drainage in eastern North Carolina has transformed extensive wetlands to productive croplands. At the start of the drainage movement in the early 1900s, approximately 200,000 hectares (one half million acres) of drained agricultural lands existed in North Carolina. The 1909 North Carolina Drainage Act allowed for more extensive drainage projects. Drainage districts provided effective drainage outlets for farms and reduced flooding for the district. The districts dramatically increased the extent of drained lands during the 20th century. Currently, it is estimated that over 2 million hectares (five million acres) of drained agricultural lands exist in North Carolina, with the majority in the Coastal Plain. Agricultural drainage has contributed to huge gains in agricultural productivity in the region. However, this drainage has contributed to regional stream water quality impairment, altered stream hydrology, and wetland conversion. Over the last three decades, much work has been focused on reducing watershed nutrient exports in eastern North Carolina. Several major strategies have been used to decrease the environmental impacts of agricultural drainage, including: agronomic management practices; controlled drainage; riparian and wetland buffers; and channel alterations. Management of agricultural drainage during the 21st century will play a crucial role in regional stream, wetland, and coastal ecosystem health.
