Summary
Completed in 1966, this Earth-type dam stands at a height of 10 feet and has a storage capacity of 112 acre-feet. With a normal storage level of 70 acre-feet and a surface area of 21 acres, Gard Lake Dam serves as a popular spot for water enthusiasts seeking leisure activities in the area.
Managed by the Rock Island District of the US Army Corps of Engineers, Gard Lake Dam poses a low hazard potential and has not been rated for its condition assessment. While it is not regulated by the state and does not require permitting or inspections, the dam continues to be a key feature in the local landscape, offering opportunities for boating, fishing, and other recreational activities along the TR-North River. Despite its simple design and limited structural features, Gard Lake Dam remains a cherished destination for water resource and climate enthusiasts in Marion County, Missouri.
Although lacking detailed information on its spillway type, inspection frequency, and emergency preparedness measures, Gard Lake Dam stands as a testament to the enduring appeal of water resources for leisure and relaxation. As an unassuming yet essential part of the local ecosystem, this dam provides a tranquil setting for residents and visitors alike to enjoy the natural beauty of the region while also serving as a reminder of the importance of sustainable water management practices in the face of climate change challenges.

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.
