Summary

Constructed in 1949, this earth dam stands at a height of 40 feet with a length of 485 feet, creating a reservoir with a storage capacity of 245 acre-feet. The dam is situated on Little Indian Creek and serves as a water resource for the surrounding area.

Despite its low hazard potential, Mount Saint Francis Dam is currently in poor condition, as assessed in February 2016. The dam lacks a spillway and outlet gates, posing a potential risk to the local community in the event of a significant discharge. With a high risk assessment rating of 2, there is a need for improved risk management measures to ensure the safety and integrity of the dam.

As an important water infrastructure in the region, Mount Saint Francis Dam requires regular inspections and maintenance to address its poor condition and mitigate potential risks. With its historical significance and vital role in water resource management, it is essential for the dam owners and regulatory agencies to prioritize the safety and maintenance of this structure to safeguard both the environment and local communities.

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.
