Summary
With a height of 11 feet and a length of 275 feet, the dam has a storage capacity of 185 acre-feet and a surface area of 74 acres. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its current condition and does not have an Emergency Action Plan in place.
Managed by the North Dakota State Water Commission, Nd No Name 127 is regulated, permitted, inspected, and enforced by state agencies to ensure its functionality and safety. The dam features an uncontrolled spillway with a width of 50 feet and no outlet gates. While it has not undergone any modifications or condition assessments recently, the dam remains a crucial infrastructure for flood risk mitigation in the region. The dam is not under the jurisdiction of any federal agency and does not have associated federal funding or oversight.
Overall, Nd No Name 127 serves as a vital component of the local government's efforts to manage flood risks in the area. With its strategic location and design, the dam plays a key role in protecting the surrounding community from potential flooding events. As climate change continues to impact water resources, the proper maintenance and monitoring of dams like Nd No Name 127 are essential to ensuring the resilience and safety of the region against future water-related challenges.

Dam Data Reference
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.
