Summary
Built in 1877, this earth dam stands at a height of 8 feet and has a length of 325 feet, creating a reservoir with a storage capacity of 80 acre-feet. The dam is associated with TR French Creek and serves a primarily recreational purpose, with a surface area of 20 acres and a drainage area of 0.6 square miles.
Despite its low hazard potential, Lake La Tsuga undergoes inspections every 5 years to ensure its structural integrity and safety. The dam has not been rated for its condition, and there is no available information on emergency action plans or risk management measures associated with the structure. The dam's location, nestled within the scenic landscape of Crawford County, makes it a vital water resource for the surrounding community and a popular spot for outdoor enthusiasts interested in water conservation and climate resilience efforts in the region.
As a significant feature in the Buffalo District, Lake La Tsuga provides both environmental and recreational benefits to the area, serving as a reminder of the importance of sustainable water resource management in the face of changing climates. With its historical significance and ongoing regulatory oversight, the dam stands as a testament to the intersection of human intervention and natural landscapes, highlighting the need for continued monitoring and conservation efforts to protect this valuable resource for future generations.

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.
