"From the reservoir, whether constructed on a large scale to hold storm water or of small size to receive the discharge from a pump, there must be provided suitable means of conducting the water to the land. The simplest, cheapest, and most widely used is the open earth ditch built in such a way as to have a gentle, uniform, grade sufficiently great for the water to flow with rapidity and yet not to wash the banks."—Government Printing Office, 1897

"It is desirable, however, on account of economy of expense and of water, that all ditches should be as nearly straight as possible, and to save distance it is sometimes necessary to build up the ditch upon a mound or, if the depression to be crossed it too great, to construct a flume."—Government Printing Office, 1897

"A modification of the basin plan, as applied to ground with considerable slope and consisting of hillside land, wherein f m is the main ditch on the highest side of the field, of which b c d e mark the boundaries. Its surface slopes in the direction of the arrows; o o and q q are "check levees," or slight embankments, built on level lines around the curved surfaces of the field. A supply ditch, i j, leads the water into the 'checks' or basins b c, o o, and q q, etc., and t w l is a waste ditch for discharging the surplus water from the checks when no longer needed." -Department of Agriculture

One way to spread water over a hillside field, "f m is the main ditch and the slope of the hill as shown by the arrows; t o, r p, and s q are small ditches or plow furrows cut on a level line around the face of the hill. The water is let into the field by the short ditch at i, and is then spread over the space b c t o by means of a marginal ditch y z, from which it is made to flow in small streams and in a regular manner over the space between it and the lower ditch t o." -Department of Agriculture

Illustrated are diagrams to explain the effect of lowering the water table by means of under draining. In undrained soil the root don't penetrate deeply. This harms the plants if a drought comes.

This device is similar to a water mill. A water mill is a structure that uses a water wheel or turbine to drive a mechanical process such as flour, lumber or textile production, or metal shaping. A water mill that generates electricity is usually called a hydroelectric plant.
