Ogallala Substation Drainage Control Keith County, Nebraska

Western Area Power Administration proposes to construct storm water drainage control at Western's Ogallala Substation near the town of Ogallala, Nebraska. The substation is experiencing water drainage erosion caused by ground water runoff from an adjacent cropland field. In order to alleviate any further damage to the facility, Western proposes to construct an earthen berm, covered with rock rip rap, along the outside edge of the southern fence line of the substation. An additional earthen/rip rap drainage control structure would be constructed approximately 24 feet outside the southeast corner of the substation in the present crop field. It will divert storm water into an existing catchment pond that is adjacent to the eastern edge of the substation.
