Summary
Built in 1977, this earth dam stands at a height of 25 feet and has a storage capacity of 40 acre-feet. Situated on the TR-BARREN FK-BOEUF CREEK, the dam provides a serene surface area of 3 acres for activities such as boating, fishing, and wildlife observation.
Owned privately, Jackson Lake Dam has a low hazard potential and is currently not rated for its condition assessment. Despite not being state regulated or inspected, the dam continues to fulfill its primary purpose of offering recreational opportunities for the local community. With its tranquil surroundings and scenic views, the dam serves as a haven for water resource and climate enthusiasts seeking solace in nature.
Managed by the St. Louis District of the US Army Corps of Engineers, Jackson Lake Dam remains a testament to responsible water resource management. While it may not have significant structural modifications or engineering features, the dam stands as a symbol of the harmonious coexistence between human recreation and natural ecosystems. As climate change continues to impact water resources, the preservation and maintenance of dams like Jackson Lake are essential for ensuring the sustainability of our planet's precious water sources.

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.
