Summary
This earth dam, completed in 1958, stands at a height of 36 feet and has a hydraulic height of 31 feet. The dam serves the primary purpose of irrigation, with a storage capacity of 351 acre-feet and a surface area of 24 acres. Despite being classified as having a low hazard potential, the dam's condition assessment is rated as poor, indicating a need for maintenance and repairs.
The dam features an uncontrolled spillway with a width of 120 feet and two slide (sluice gate) outlet gates. Although the risk assessment is moderate, with a rating of 3, there is no Emergency Action Plan (EAP) prepared for the dam as of the last inspection in July 2019. The dam is under state jurisdiction and regulation, with permitting, inspection, and enforcement processes in place. It is important for water resource and climate enthusiasts to monitor the condition of Rocky Ford and advocate for necessary improvements to ensure its safety and functionality for irrigation purposes.
In the event of a potential emergency or hazard, it is crucial to have an updated EAP that meets guidelines and includes relevant inundation maps and emergency contacts. With a moderate risk level and a poor condition assessment, there is a need for proactive risk management measures to prevent any potential incidents at Rocky Ford. Given its critical role in irrigation and water resource management, stakeholders should work together to address the dam's maintenance needs and enhance its overall safety and resilience in the face of changing climate conditions.

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.
