Summary
Owned privately, the dam stands at a height of 28 feet and spans 375 feet in length, holding a maximum storage capacity of 32 acre-feet. With a low hazard potential and a moderate risk assessment rating, the dam is classified as an earth structure with an uncontrolled spillway type.
Designed by the USDA NRCS, Creti Dam plays a crucial role in managing water resources in the area, particularly in preventing erosion and mitigating flood risks. Despite not being regulated by the state, the dam serves as a key infrastructure for the surrounding community. The risk management measures for the dam are currently not specified, indicating a need for further evaluation and planning to ensure the safety and effectiveness of the structure in the face of changing climate conditions.
As climate change continues to impact water resources and infrastructure, Creti Dam stands as a vital component in the local ecosystem. With a focus on grade stabilization and a storage capacity of 32 acre-feet, the dam provides essential benefits for water management in the region. Moving forward, continued monitoring and assessment of the dam's condition and risk management measures will be crucial to ensure its 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.
