A method of and apparatus for controlling drainage / irrigation of a field includes laying out a network of drainage tiles, which typically may include a main line and a number of lateral lines, extending from higher elevations to lower elevations and exiting through a manually controlled main valve to a drainage ditch.A series of level-responsive valves are incorporated in the main and lateral lines at selected elevations. Each level-responsive valve is normally open until the ambient water level reaches a predetermined level relative to the valve. When the manual valve is closed and a certain level of water is reached adjacent a level-responsive valve, it causes that level-responsive valve to close, thereby cutting off drainage of higher elevations. When it is desired to retain water at higher elevations in a field, the manual valve is closed permitting water to accumulate and be retained at higher elevations by closing the level-responsive valves in sequence at progressively higher elevations as the level of retained water rises, thereby causing a cascading or “terracing” of water stored at upper levels. When the manual valve is opened, the field drains normally. The level-responsive valve may be a flotation valve. A modification of a flotation type level-responsive valve includes an overflow tube which permits excessive water at higher placement elevations to bypass the closed level-responsive valves, thereby permitting the field to drain under conditions of excess water into a standpipe at the manual valve.
