Summary
This earthen dam, completed in 1953, stands at 20 feet high and spans 360 feet in length, with a storage capacity of 60 acre-feet. The lake serves various purposes, including flood control on the TR-Clear Boggy Creek and providing recreational opportunities for the community of Ahloso.
Despite being classified as having a low hazard potential, Engel Lake is considered to have a very high risk level, with a risk assessment rating of 1. While the dam's condition is currently not rated, regular inspections are carried out every five years to ensure its safety and functionality. The dam features a controlled spillway with a width of 1 foot, along with a valve outlet gate for water release. The area surrounding the lake is relatively small, with a surface area of 10 acres.
With its scenic location and important role in water management, Engel Lake is a valuable asset to the community and a crucial part of the local ecosystem. As climate change continues to impact water resources, it is essential to monitor and maintain structures like Engel Lake to ensure their resilience and effectiveness in the face of evolving environmental challenges.

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.
