Summary
This private-owned earth dam, with a height of 19 feet and a length of 1200 feet, serves primarily for fire protection, stock, and as a small fish pond. The dam has a storage capacity of 235 acre-feet, with a normal storage level of 177 acre-feet, making it an essential water resource for the surrounding area.
Despite its age, the dam has not been rated for its condition assessment and lacks a hazard potential evaluation. However, with a high risk assessment score of 2, it is crucial for the proper maintenance and monitoring of Powell Lake Dam to ensure the safety of the downstream community. While the dam does not have a spillway, its purpose extends beyond just water storage, as it also provides recreational opportunities in addition to its primary functions.
With its picturesque location on the Small Greens Creek and proximity to LaGrange, Powell Lake Dam stands as a vital structure for water resource management and climate enthusiasts. As it continues to play a significant role in fire protection, stock maintenance, and recreational activities, it is essential for stakeholders to prioritize its upkeep and safety to mitigate any potential risks associated with its high hazard potential rating.

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.
