Summary

Standing at 25 feet high and 300 feet long, this dam serves primarily for recreational purposes, offering a storage capacity of 147 acre-feet. While the hazard potential of the dam is currently undetermined, it is subject to regular state inspection, enforcement, and permitting by the Department of Conservation and Recreation.

Despite lacking a specific completion date and condition assessment rating, Blenheim Road Mid-E Dam remains a significant structure in the Norfolk District. With its picturesque location and potential for recreational activities, the dam provides a valuable resource for water and climate enthusiasts in the area. As a non-federal dam, it falls under state jurisdiction and has not been associated with any federal agencies for funding, design, construction, or regulatory oversight.

Although the specifics of its emergency action plan, risk assessment, and management measures are yet to be determined, the dam's presence highlights the importance of maintaining and monitoring critical infrastructure to ensure the safety and enjoyment of nearby communities. As climate change continues to impact water resources, structures like Blenheim Road Mid-E Dam play a vital role in managing and conserving essential water supplies while providing opportunities for outdoor recreation and appreciation of the natural environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
