L , ( {~. NORFOLK UN I T* . The potential Norfolk Unit is located in Madison, Stanton, Cumlng and Dodge Counties. The Elkhorn Val ley Water Resources Association and the Lower Elkhorn Watershed Planning Board have shown their interest in this multi-purpose development. The U. S. Bureau of Reclamation is planning this project. Current Status A reconnaissance report has been prepared on this unit but before further steps can be taken toward construction, local interest must be evident, and Congress must authorize a feaslbl Ilty study and appropriate funds for further study. Description of Project Area The Norfolk Unit area is made up of valley bottom land, val ley terraces and uplands. The upland areas are generally sloping and dissected by smal I drains. The soi I is primari Iy si Ity loess. Poor drainage conditions exist in parts of the val ley lands. However, these lands are not proposed for project irrigation. Rainfal I averages 28 inches, with approximately 21 inches fal I lng during the months of Apri I through September. The economy of this area is basically agricultural. Most business stems from the pro- cessing and marketing of farm products. Extent of Project Investiqations The potential for the development of irrigation in the area was studied by the Bureau of Reclamation during the late 1940's and early 1950's. The drought of the 1950's adversely affected the local economy of this area and stimulated local interest in the initiation of a reconnaissance investigation by the Bureau of Reclamation. Plan Features Major features of the Norfolk Unit would be the Monterey Dam and Reservoir and the \1arner- vi I Ie Diversion Works. Monterey Dam would be located on Pebble Creek. a tributary of the E I khorn River, approx imate Iy seven mil es southwes t of I,'lest Po i nt in Cum i ng County. A 3500 c.f.s. uncontrolled morning-glory type spillway would be located on the right side of the dam embankment. The river outlet works, located near the center of the dam embankment. would have a discharge capacity of 900 c.f.s. A 400 c.f.s. canal outlet works located near the right end of the dam embankment would serve 25,000 acres of upland between Pebble and f~aple Creeks by gravity. The Warnervi I Ie Diversion Dam. located on the Elkhorn River approximately four mi les southeast of Norfolk, would consist primari Iy of an uncontrol led overflow spi I Iway and two canal headworks. A 500 c.f.s. headworks and sluiceway adjacent to the right end of the spi Ilway would divert river flows to the Monterey Feeder Cana I to both de I j ver water to the ~I~onterey Reservo i r and serve 2900 acres wi th i rr i gat i on water enroute. A 90 c. f .s. headworks and s! u i ce~lay adjacent to the I eft end of the sp i II way wou I d d; vert river f rows to the Norfo I k Cana I, to serve about 5100 acres of land on the north side of the river. The project lands receiving irrigation service would be located from Norfolk to Wisner and in upland areas between Pebble and Maple Creek. Prolect Benefits Direct benefits are derived for this project from irrigation, recreation. fish and wi Idl ife and flood control. The recreation, fjsh and wi ldl ife features of this project wi I j provide 924,000 recreation days and 43.700 fisherman days annually. The flood control benefits would be incidental to the operation of the reservoir and would reduce annual damages on Pebble Creek about 30 percent. . * llLower Basin.
