Summary
Completed in 1827, this earth dam with a buttress core type reaches a height of 10 feet and spans 400 feet in length. With a storage capacity of 3,875 acre-feet and a surface area of 775 acres, the dam plays a significant role in managing water resources in the region.
Despite its historical significance, Lake Manitou Dam faces challenges in terms of its condition assessment, marked as poor during the last inspection in 2011. The dam's hazard potential is deemed significant, with a high-risk assessment rating of 2. This highlights the urgent need for rehabilitation and maintenance to ensure the safety and functionality of the dam for both recreational and environmental purposes.
With the dam being state-regulated and inspected, there is hope for improved risk management and maintenance measures in the future. However, the current condition of Lake Manitou Dam underscores the importance of ongoing monitoring and investment in infrastructure to safeguard water resources and mitigate climate-related risks in the region.

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.
