Summary
1 in South Dakota, designed by Ducks Unlimited, stands along the TR Beaver Creek and was completed in the year 2000. This private earth dam has a height of 16 feet and a length of 304 feet, providing storage for up to 74 acre-feet of water. With a low hazard potential and a moderate risk assessment rating, the dam has not been recently inspected but is maintained to meet state regulatory standards.
Located in Meade County, South Dakota, Haines Dam No. 1 serves as a vital structure for water resource management in the area. Its uncontrolled spillway with a width of 100 feet can handle a maximum discharge of 1350 cubic feet per second. Although the dam's condition assessment is currently listed as "Not Rated", its low hazard potential suggests that it poses minimal risk to surrounding communities.
With the primary purpose of water storage and management, Haines Dam No. 1 contributes to the sustainability of the local watershed. While its associated structures and inspection frequency are not specified, the dam's design and construction by Ducks Unlimited reflect a commitment to environmental conservation and water resource protection. As a key feature in the St. Paul District, this earth dam plays a crucial role in maintaining the ecological balance of the region.

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.
