Summary
This earth dam stands at a height of 30 feet, with a storage capacity of 273 acre-feet and a normal storage of 170 acre-feet. The dam is situated on TR-LOCUST CREEK, within the Rock Island District of Missouri.
Despite its importance in providing water supply, Linneus Lake Dam is classified as having a high hazard potential. The dam is primarily used for water supply purposes and is owned by the Local Government. With a drainage area of 530 square miles, the dam covers a surface area of 17 acres. While the dam's condition is currently rated as "Not Rated," it has not undergone recent inspections or assessments.
For water resource and climate enthusiasts, Linneus Lake Dam presents a unique opportunity to explore the intersection of infrastructure and environmental sustainability. As a critical water supply source in Missouri, the dam's maintenance and management are crucial for ensuring water security in the region. Understanding the complexities of dam construction, hazard potential, and risk management at Linneus Lake Dam can offer valuable insights into the broader challenges facing water resource management in a changing climate.

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.
