Summary
Constructed in 1968, this earth dam stands at a height of 25 feet and stretches 450 feet in length, with a storage capacity of 85 acre-feet. The dam's primary purposes include fire protection, stock or small fish pond, grade stabilization, and recreation, making it a multifunctional asset for the local community.
Despite being privately owned, James Lake Dam falls under the oversight of the Rock Island District of the US Army Corps of Engineers. With a low hazard potential and a moderate risk assessment rating, the dam is essential for managing water resources in the area. While not currently rated for its condition, regular inspections and risk management measures ensure the safety and integrity of this structure for the surrounding environment and residents. The dam's location on the TR-North Fork river stream adds to its significance in preserving local ecosystems and supporting recreational activities in the region.
Overall, James Lake Dam stands as a key feature in the water resource management and climate adaptation efforts of Knox County, Missouri. Its role in providing habitat for wildlife, recreational opportunities, and water storage underscores its importance in sustaining the local environment. With a focus on safety and risk management, this dam continues to be a valuable asset for both the community and the natural landscape it serves.

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.
