Summary

Designed by Larry H. Attebery, this Earth-type dam boasts a structural height of 39.5 feet and a length of 250 feet, serving as a crucial barrier on the unnamed tributary of Elm Creek. With a storage capacity of 46.5 acre-feet and a normal storage of 34.4 acre-feet, this dam plays a vital role in regulating water flow and minimizing flood risk in the region.

Despite its low hazard potential and satisfactory condition assessment, the Spring Lake Silt Pond Dam is subject to state regulation, inspection, and enforcement. The Dam and Reservoir Safety Program of Missouri oversees its permitting, inspection, and regulatory processes, ensuring that it meets safety standards and poses no immediate threat to the surrounding community. With an uncontrolled spillway and outlet gates, this dam is designed to handle a maximum discharge of 18 cubic feet per second, further reducing the risk of overtopping during heavy rainfall events.

While the Spring Lake Silt Pond Dam has yet to undergo any significant modifications since its construction, it remains a critical piece of infrastructure in Adair County, Missouri. With a moderate risk rating and a strategic location in the Rock Island District, this dam serves as a model for private dam ownership and management, highlighting the importance of proactive maintenance and oversight in safeguarding our water resources and mitigating the impacts of climate change.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
