Summary
This private earth dam stands at 32 feet high and serves multiple purposes including fire protection and stock and small fish pond management. With a storage capacity of 67 acre-feet and a surface area of 4 acres, Crandall Dam plays a crucial role in water resource management in the area.
Despite being classified as having a low hazard potential, Crandall Dam is regularly monitored for its structural integrity and safety. The dam's uncontrolled spillway and lack of outlet gates suggest a simpler design focused on its primary purposes. The risk assessment for Crandall Dam is moderate, indicating a need for ongoing risk management measures. Its location in a relatively rural area underscores the importance of efficient emergency response plans and regular maintenance to ensure the safety of nearby communities and the environment.
For water resource and climate enthusiasts, Crandall Dam presents an intriguing case study of a small-scale earth dam with multiple functions. As a privately-owned structure, it highlights the diverse roles dams play in managing water supply and supporting local ecosystems. The dam's design and risk assessment offer valuable insights into the challenges of balancing water management needs with environmental and safety considerations. As climate change continues to impact water resources, understanding the role of dams like Crandall in adapting to new challenges becomes increasingly important for sustainable water management practices.

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.
