Summary
The dam stands at a height of 15 feet and has an undetermined hazard potential. Despite being not regulated by the state, the impoundment serves an unknown primary purpose and lacks detailed information on its design and construction.
Located within the St. Paul District, Upper Deadfish Impoundment is currently assessed as not available for condition assessment, with its emergency action plan status and risk management measures remaining undisclosed. The impoundment's spillway width is listed as 0, indicating a potential need for further infrastructure or maintenance. While the structure is not under the jurisdiction of state agencies for inspection or enforcement, its risk assessment and inundation maps are yet to be prepared and updated.
With its unique name and intriguing characteristics, Upper Deadfish Impoundment presents an opportunity for water resource and climate enthusiasts to delve into the complexities of its management and potential environmental impact. The impoundment's undetermined hazard potential and lack of detailed information on its purpose and infrastructure warrant further investigation and research, making it a fascinating case study for those interested in water resource management and climate resilience.

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.
