Summary
The dam is primarily an earth type, standing at 18 feet tall with a storage capacity of 77 acre-feet. It serves as a low hazard structure with a poor condition assessment as of 2011, indicating potential safety concerns that may need to be addressed in the future.
Despite its historical significance and recreational value, Seven Mile Stream Dam is in need of maintenance and assessment to ensure its safety and functionality. With state regulation and inspection in place, there is an opportunity for improvement and risk mitigation to better protect the surrounding environment and communities. The dam's location on Seven Mile Stream adds to its importance in managing water resources and climate impacts in the region, calling for a comprehensive approach to its management and upkeep.
As water resource and climate enthusiasts, there is a responsibility to advocate for the proper maintenance and assessment of structures like Seven Mile Stream Dam. By supporting state-regulated inspection and enforcement measures, we can strive to ensure the safety and sustainability of our water resources for future generations. This historical dam serves as a reminder of the intersection between human activity and nature, highlighting the need for responsible stewardship of our waterways in the face of evolving climate challenges.

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.
