Summary
The dam, completed in 1935, is an earthen structure standing at a height of 25 feet with a hydraulic height of 20 feet, creating a reservoir with a storage capacity of 640 acre-feet. The lake covers a surface area of 66 acres and is fed by Tribgray's Creek, serving as a vital resource for the surrounding community in Shandy.
Despite its satisfactory condition assessment, Lake Lajoie poses a significant hazard potential and is classified as having a moderate risk level. The dam is equipped with an uncontrolled spillway and lacks outlet gates. Regular inspections are conducted, with the last one taking place in June 2020, emphasizing the commitment to ensuring the safety and integrity of this essential water infrastructure. With a drainage area of 1.21 square miles, the lake plays a crucial role in water management and conservation efforts in the region.
As a focal point for water resource and climate enthusiasts, Lake Lajoie offers a glimpse into the intricate balance between human development and environmental stewardship. With its historical significance, regulated status, and moderate risk level, the lake serves as a reminder of the importance of responsible water resource management in the face of changing climate conditions. As efforts continue to maintain the dam's integrity and safety, Lake Lajoie stands as a testament to the ongoing commitment to safeguarding water resources 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.
