Summary
[edit]DescriptionBaldhill Dam maintenance (9578945888).jpg | Joel Zietz, a maintenance worker at Baldhill Dam operates a pump during the spillway de-watering effort at the dam during a periodic inspection of the facility. Located near Valley City, N.D., Baldhill Dam impounds the Sheyenne River to create Lake Ashtabula. The Corps’ periodic inspections are performed every five years as part of its dam safety program. Routine or annual inspections are conducted at the site each year but do not involve dewatering the stilling basin. |
