Summary
This earth dam stands at a towering height of 95 feet and has a storage capacity of 18,378 acre-feet. With a high hazard potential but deemed to be in satisfactory condition, this dike plays a crucial role in managing water resources in the region.
Managed by the Omaha District of the US Army Corps of Engineers, Diamond Creek Dike is subject to state regulation and inspection, ensuring its safe and effective operation. Despite being uncontrolled, the spillway of the dike helps mitigate potential risks during high flow events. With its strategic location in Park County, this structure is a key component in the local water infrastructure, contributing to flood control and water supply management efforts.
Water resource and climate enthusiasts can appreciate the importance of Diamond Creek Dike in maintaining the ecological balance of the area while safeguarding against potential hazards. Its role in managing water flow and storage underscores the need for effective dam management practices to ensure the sustainability of these vital infrastructure projects in the face of changing climatic conditions.

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.
