Summary
Built in 1997 by the USDA NRCS, this dam serves the primary purpose of grade stabilization with a height of 29 feet and a length of 371 feet. With a storage capacity of 22 acre-feet and a drainage area of 180 acres, Jackie Hague plays a crucial role in managing water resources in the region.
Despite being categorized as low hazard potential, Jackie Hague is considered to have a moderate risk level of 3. This earth dam, constructed with stone core and soil foundation, has not been rated for its condition as of yet. The spillway design of this dam is uncontrolled with a width of 10 feet, and it does not have any outlet gates. The last inspection of Jackie Hague was conducted in May 1999, with a recommended inspection frequency of once per year.
Located within the Rock Island District, Jackie Hague is a key structure for water resource management in the area. While it may have a moderate risk level, its low hazard potential and the absence of regulatory agencies indicate that it is currently functioning effectively for grade stabilization along the TR-MUDDY river in Mercer, Missouri. As a significant earth dam with a storage capacity of 22 acre-feet, Jackie Hague remains a valuable asset for climate enthusiasts and water resource managers alike.

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.
