Summary
Hague, a privately-owned dam located in Hyde, South Dakota, was completed in 1948 and serves as a crucial structure on the TR-Wolf Creek river system. This Earth-type dam stands at a height of 14 feet with a length of 725 feet, providing storage for up to 1098 acre-feet of water. With a low hazard potential and a current condition assessment of "Not Rated," M. Hague plays a significant role in water resource management in the region.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), M. Hague is subject to state regulation, permitting, inspection, and enforcement. While the dam itself has not been rated for its condition, its low hazard potential suggests that it poses minimal risk to surrounding communities. Despite its age, M. Hague continues to fulfill its primary purpose of regulating water flow and providing storage for the TR-Wolf Creek watershed.
As a vital component of the St. Paul District's water infrastructure, M. Hague contributes to flood control and water supply management in the region. Although the dam has not undergone recent inspections or assessments, its historical significance and operational functionality underscore its importance in safeguarding water resources and supporting climate resilience efforts in South Dakota.

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.
