Summary
The dam, situated on TR-East Fork Medicine Creek, stands at a height of 32 feet and has a storage capacity of 154 acre-feet. The reservoir created by the dam covers an area of 9 acres and serves as a water supply for various recreational activities.
Despite being unregulated by the state, Humphrey's Lake Dam has a low hazard potential and is currently in a not rated condition assessment. The dam's structural integrity and safety are maintained through regular inspections, although no specific inspection frequency is listed. The dam's emergency action plan (EAP) status, risk assessment, and management measures are not provided in the data, suggesting a need for further evaluation and documentation in case of emergencies.
Located within the Rock Island District, Humphrey's Lake Dam offers a tranquil setting for outdoor enthusiasts to enjoy water-based activities such as fishing, boating, and swimming. With its picturesque surroundings and recreational opportunities, the dam serves as a valuable resource for the local community while also contributing to the region's water supply needs. As climate change continues to impact water resources, maintaining the safety and functionality of dams like Humphrey's Lake Dam becomes increasingly important for sustainable water management in the future.

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.
