Summary
This private Earth dam stands at 25 feet high with a length of 566 feet, providing a storage capacity of 428 acre-feet. Despite its age, the dam has a low hazard potential but is in poor condition as of its last inspection in October 2017, conducted by the Nebraska Department of Natural Resources.
Managed by private owners, Turner Dam is regulated by the state and undergoes regular inspections, with a frequency of every 5 years. While the dam's primary purpose is irrigation, its location within the Omaha District of the US Army Corps of Engineers highlights its importance in water resource management. The dam's proximity to Ardmore SD and its role in controlling the flow of the South Antelope Creek make it a crucial infrastructure for the region.
Although Turner Dam currently has a poor condition assessment, its significance in providing water for agricultural needs in the area cannot be understated. With its low hazard potential and regulated status, ongoing maintenance and potential rehabilitation efforts could ensure the continued safe operation of this vital water resource infrastructure in Nebraska's Sioux County.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
