Summary
This earth dam, completed in 1952, stands at a height of 18 feet with a hydraulic height of 14 feet and a length of 150 feet. The dam has a low hazard potential and is categorized as having a moderate risk level.
Situated on Palarm Creek, the dam serves as a crucial resource for water storage with a capacity of 128 acre-feet. While the dam does not have a controlled spillway, its uncontrolled spillway type is designed to handle a maximum discharge of 692 cubic feet per second. Despite being privately owned, the dam is not regulated by the state and has not been inspected or rated for its condition. As climate enthusiasts, we recognize the importance of maintaining and monitoring such structures to ensure their safety and effectiveness in the face of changing climate conditions.
Diehl Lake Dam's historical significance and its role in water management make it a notable site for water resource and climate enthusiasts. With its unique design and purpose, this structure highlights the intersection between human intervention in water management and the need for sustainable practices in the face of climate change. As we continue to explore and protect our water resources, understanding the importance of structures like Diehl Lake Dam is crucial for ensuring a resilient and adaptive water management system in the future.

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.
