Summary
2, located in Niobrara, Wyoming, is a privately owned earth dam built in 1950 for the primary purpose of irrigation along the Scoby Draw river. With a dam height of 29 feet and a storage capacity of 320 acre-feet, this structure plays a crucial role in managing water resources in the region. Despite its low hazard potential, a recent inspection in June 2019 found the condition of Rumney No. 2 to be unsatisfactory, indicating a need for maintenance and potential improvements.
The dam's spillway, an uncontrolled type with a width of 110 feet, provides critical flood control measures to mitigate potential risks. Furthermore, the presence of a slide gate for outlet control adds to the operational efficiency of the structure. Although the risk assessment categorizes Rumney No. 2 as moderate, the structure's capacity to meet irrigation demands and contribute to the overall water management in the area underscores its importance for sustainable agriculture and climate resilience initiatives. Climate enthusiasts and water resource experts alike will find Rumney No. 2 an intriguing case study in balancing water supply security with infrastructure maintenance challenges.

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.
