Summary

Hegge Dam, is a privately owned structure located in MARMARTH, North Dakota. Built in 1963 by USDA NRCS, this earth-type dam stands at a height of 24 feet and spans a length of 570 feet. Its primary purpose is irrigation, with a storage capacity of 398 acre-feet and a normal storage level of 270 acre-feet. The dam is regulated by the NDSWC, ensuring that it meets state permitting, inspection, and enforcement requirements.

Situated on LITTLE BEAVER CREEK-TR, Bradac Dam serves as a crucial water resource for the surrounding area, covering a surface area of 45 acres and draining a watershed of 5.78 square miles. The spillway, with a width of 150 feet, is uncontrolled, and the dam is equipped with a single slide (sluice gate) outlet gate for water release. Despite a moderate risk rating of 3, the dam is categorized as having low hazard potential, providing a stable source of water for irrigation purposes.

Managed without federal involvement, Bradac Dam is a testament to private ownership and local regulation in water resource management. While its condition assessment is currently not rated, the dam continues to support agricultural activities in Bowman County, North Dakota, under the oversight of the NDSWC. With its strategic location and functional design, Bradac Dam exemplifies the importance of sustainable water infrastructure in the face of changing climate patterns and increasing demands for water resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
