Summary
Standing at a height of 21 feet and with a storage capacity of 337 acre-feet, this earth dam serves as a key feature for water resource and climate enthusiasts in the area. Despite its low hazard potential and current "Not Rated" condition assessment, the dam has not been inspected recently and lacks emergency action plans and risk assessment measures.
Managed by the Rock Island District of the US Army Corps of Engineers, Jamesport Lake Dam offers a surface area of 30 acres and normal storage capacity of 160 acre-feet for outdoor activities and wildlife habitat. Although the dam's primary purpose is recreational, its role in water resource management and environmental conservation cannot be overlooked. With the lack of detailed data on spillway type, outlet gates, and inspection frequency, there is potential for increased interest and research in the dam's structural integrity and long-term maintenance plans for sustainable water management.
As climate change continues to impact water resources and infrastructure, Jamesport Lake Dam serves as a focal point for studying the intersection of recreational needs, ecological balance, and climate adaptation strategies. With a unique blend of historical significance and modern challenges, this dam invites further exploration and engagement from water resource and climate enthusiasts seeking to understand the complexities of managing water systems in a changing world.

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.
