Summary
The dike is a concrete structure with a height of 8 feet and a length of 75 feet, providing essential water management for the region. With a normal storage capacity of 69 acre-feet and a maximum storage capacity of 138 acre-feet, the dike serves as a crucial barrier against excess water flow during heavy rainfall or storm events.
Managed by federal agencies and regulated by the Maine Emergency Management Agency (MEMA), Hobart Bog Dike is a key component in the state's flood control infrastructure. With a low hazard potential and a condition assessment currently not rated, the dike stands as a reliable defense against water-related emergencies. While its primary purpose is flood risk reduction, the structure also serves the secondary purposes of supporting fish and wildlife habitats and maintaining a fish and wildlife pond. Despite being over a century old, Hobart Bog Dike continues to play a critical role in safeguarding the local community and environment from water-related risks.
As an essential asset in water resource management, Hobart Bog Dike exemplifies the importance of sustainable water infrastructure in mitigating climate-related challenges. With ongoing inspections and state permitting in place, the dike ensures continued protection against floods and other water-related hazards. Supported by federal funding and designed to withstand hydraulic pressures, the dike remains a testament to the resilience and foresight of early water resource engineers. For water resource and climate enthusiasts, Hobart Bog Dike serves as a symbol of effective water management and environmental stewardship in the face of changing climate patterns.

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.
