Summary
Built in 1960, this earth dam stands at a height of 20.9 feet with a hydraulic height of 19.2 feet, providing a storage capacity of 141 acre-feet. With a surface area of 15 acres and a drainage area of 0.09 square miles, Jameson serves primarily for flood control purposes, with a low hazard potential rating and moderate risk assessment.
Despite being privately owned and not regulated by the state, Jameson undergoes inspections every five years, with the last one conducted in May 2017. The dam features an uncontrolled spillway and has no associated locks or outlet gates. Although its condition assessment is currently listed as "Not Rated," the risk management measures for Jameson are moderate, indicating a level of caution and preparedness in place for potential emergencies. Overall, Jameson presents an interesting case study for water resource and climate enthusiasts, showcasing the balance between private ownership, regulatory oversight, and risk management in dam infrastructure.

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.
