Summary
Built in 1913, this earth dam stands at 33 feet high and stretches 100 feet in length, holding a storage capacity of 600 acre-feet. The primary purpose of the dam is for recreation, with a surface area of 26 acres and a drainage area of 1.86 square miles along the Mohawk River.
Despite its recreational appeal, Lake Gloriette Dam poses a high hazard potential with a poor condition assessment as of 2013. The dam's spillway, which is uncontrolled with a width of 19 feet, indicates the need for ongoing inspections and maintenance to ensure public safety. The risk assessment for the dam is moderate, emphasizing the importance of implementing effective risk management measures to mitigate any potential hazards.
Water resource and climate enthusiasts interested in the preservation of Lake Gloriette Dam should be aware of its current condition and the need for regular inspections and maintenance. The dam's historical significance, combined with its recreational value, underscores the importance of ensuring its structural integrity and safety for the surrounding community and the environment. Collaboration between state agencies and stakeholders is crucial in implementing risk management measures and safeguarding this vital water resource for future generations.

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.
