Summary
Owned privately, this Earth-type dam has a structural height of 25 feet and a storage capacity of 107 acre-feet. With a normal storage of 55 acre-feet and a surface area of 8 acres, the dam plays a crucial role in maintaining water resources in the region.
Although not regulated by the state, Stallman Lake Dam has a high hazard potential and has not been rated for its condition assessment. The dam, with a drainage area of 50 square miles, is located on the TR to Cedar Fork Boeuf Creek and falls under the jurisdiction of the St. Louis District. Despite lacking inspections and enforcement by state agencies, the dam's importance for fire protection and recreational purposes highlights the need for continued monitoring and maintenance to ensure the safety and preservation of the water resource.
Managed without federal funding or oversight, Stallman Lake Dam poses potential risks that require attention from private owners to mitigate any hazards. While the dam has not been assigned a Dam Safety Action Classification (DSAC) or undergone a risk assessment, the lack of updated emergency action plans and inspection records raises concerns about the dam's resilience in the face of climate change impacts. As water resource and climate enthusiasts, staying informed and advocating for proper management of dams like Stallman Lake is crucial for sustainable water management and environmental protection.

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.
