Summary
With a maximum storage capacity of 40 acre-feet and a normal storage capacity of 25 acre-feet, this dam sits on the TR-BEAR CREEK river/stream, serving as a vital resource for the surrounding area. Standing at a height of 25 feet, this buttress dam has a surface area of 3 acres and drains a 35-acre watershed.
Despite its low hazard potential, Gabriel Lake Dam South has not been rated for its condition assessment, and inspection frequency is listed as zero. The dam has not been modified in recent years and lacks specific information on construction dates or outlet gates. Emergency action plans and risk assessments for the dam are also not readily available, raising concerns about preparedness in case of potential issues. The structure falls under the jurisdiction of the Rock Island District of the US Army Corps of Engineers and is not currently regulated by the state of Missouri.
Water resource and climate enthusiasts interested in Gabriel Lake Dam South may find it intriguing as a privately owned recreational dam with potential water supply benefits for the surrounding area. However, the lack of detailed information on its condition, maintenance, and emergency response plans highlights the need for further monitoring and assessment to ensure the safety and reliability of this important water resource infrastructure. The dam's location on TR-BEAR CREEK, in Worth County, Missouri, adds to its significance as a potential focal point for conservation efforts and sustainable water management practices in the region.

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.
