Excerpt from Farm Drainage in the United States: History, Status, and Prospects The most recent rapid developmental era for drainage reclamation drew to a close about 1965. Drainage is the most extensive soil and water manage ment activity in agriculture. Approximately 110 million acres of the land within farms are artificially drained in the United States. About 9 million acres, or 25 percent, of the irrigated cropland in the Western States are artificially drained. Drainage can also have adverse effects in some situations by reducing or degrading wetlands vital to wildlife and serving hydrologic functions such as flood flow regulation. Drainage activities can also affect the quality of water bodies receiving drainage water. Drainage investigations in usda began with the Reclamation Act of 1902. This act is best known as creating the Bureau of Reclamation in the Depart ment of the Interior. A drainage unit to service irrigation project planning was simultaneously authorized for usda. In 1962, Public Law 87-732, the Drainage Referral Act, was enacted which prohibited usda from assisting landowners in draining potholes and marshes in Minnesota and the Dakotas if wildlife would be materially harmed. Currently, usda technical and financial assistance is no longer provided as a matter of policy except in unique circumstances as part of a conservation system related to irrigation water control, or as an essential element of an environmental system of practices. Thus, for usda, this publication represents an end to the era of strong usda support and assistance for drainage development activities.
