Summary
2 Dike A, located in Fremont, Wyoming, is a critical structure designed by Harold O'Malley for the purpose of creating a Fish and Wildlife Pond. This earth dam, completed in 1973, stands at a height of 7 feet with a hydraulic height of 4 feet and a length of 620 feet. The dam has a storage capacity of 84 acre-feet and covers a surface area of 45 acres, making it a vital habitat for various aquatic species in the region.
Managed by the State agency SEO, the dam at Ocean Lake Habitat No. 2 Dike A is state-regulated, inspected, and enforced to ensure its structural integrity and overall safety. With a low hazard potential and fair condition assessment, the dam poses a moderate risk, leading to a regular inspection frequency of 5 years. The presence of an uncontrolled spillway and other controlled outlet gates further enhances the dam's functionality and ability to manage water levels effectively, contributing to the conservation of the surrounding ecosystem.
In the event of emergencies, the dam at Ocean Lake Habitat No. 2 Dike A is equipped with emergency action plans and designated emergency contacts. Despite its moderate risk assessment, the dam's risk management measures are currently unspecified, suggesting a potential area for improvement in ensuring the long-term resilience and sustainability of this essential water resource infrastructure for fish and wildlife conservation in Wyoming.

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.
