<br />Cedar Valley, is a fertile,oomparatively level area lying southwest of
<br />Gering, Nebraska. It is surrounded on three sides by a range of hills
<br />. averaging about 600 feet in height above the valley floor, and is open to
<br />the eastv'ard. Originally the Gering Valley was drained by a shallow,
<br />poorly defined, swale-like, unnamed, channel. As irrigation projects were
<br />oompleted in the valley, a system of drainage canals was developed in
<br />erder tc lower the water table and to handle flood flows. The main drain-
<br />age canal, now known as, Gering Main Drain, originates in Section 10. Town-
<br />ship 21 North, Range 56 West, and follows ~pproximately the old water
<br />eourse, to enter tho North Platte River three miles east of Gering, Nebraska
<br />(see plate No.2). All the land below the existing irrigation canals in
<br />this area is under cultivation, except for the roads and small areas of
<br />seepage land. The major crops grown in the valley a re sugar be'ets, beans,
<br />potatoes, cereal grains, hay and forage, sugar beets being the main cash
