Summary
This private earth dam stands at a height of 21 feet and serves the primary purposes of fire protection, stock, and small fish pond. With a storage capacity of 120 acre-feet and a surface area of 5 acres, Crist Dam plays a crucial role in regulating water flow and providing essential resources for the surrounding area.
Despite being classified as having a low hazard potential, Crist Dam is subject to moderate risk with a rating of 3. The dam features an uncontrolled spillway with a width of 20 feet, designed to handle a maximum discharge of 11.4 cubic feet per second. While the dam has not been inspected since its completion in 1999, it remains in a not rated condition assessment, suggesting a need for further evaluation to ensure its structural integrity and continued functionality.
With no state regulation or permitting required for Crist Dam, its operations and maintenance fall under the responsibility of the private owner and the USDA NRCS. As a vital resource for water management and conservation in the area, Crist Dam serves as a key component in supporting the local ecosystem and providing essential services for fire protection and agricultural activities.

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.
