Summary
This private dam stands at a height of 45 feet and has a hydraulic height of 36 feet, with a storage capacity of 205 acre-feet and a normal storage capacity of 60 acre-feet. The dam, primarily made of earth with a buttress core type, spans a length of 300 feet and has a spillway width of 60 feet.
Managed by the DAM AND RESERVOIR SAFETY PROGRAM in Missouri, Lowell Pierce Dam is regulated, inspected, and enforced by the state, ensuring its safety and compliance with regulations. The dam has a high hazard potential and has been assessed to be in satisfactory condition as of 2011. While the risk assessment is moderate, the dam's emergency action plan and risk management measures are not currently updated, highlighting the importance of ongoing monitoring and maintenance to mitigate potential risks and ensure the safety of the surrounding community.
With a drainage area of 694 square miles and a maximum discharge capacity of 377 cubic feet per second, Lowell Pierce Dam plays a crucial role in water resource management for the TR MILL CREEK and surrounding areas. The dam's strategic location and design not only support local wildlife and recreational activities but also contribute to the overall resilience and sustainability of the region's water infrastructure in the face of changing climatic conditions.

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.
