Summary
Built in 1960, this earth dam stands at a height of 25.7 feet and has a storage capacity of 219.7 acre-feet, providing essential protection for the surrounding area. Despite its importance, the dam's condition assessment is rated as poor, highlighting the need for maintenance and potential upgrades to ensure its continued effectiveness.
Owned privately, the Rh&W Grazing Association Dam is regulated by the Nebraska Department of Natural Resources, with regular inspections and enforcement measures in place. With a low hazard potential, the dam is considered a crucial asset for water resource management in the region, providing a surface area of 14.4 acres and a drainage area of 1.79 square miles. However, the dam's condition assessment raises concerns about its long-term viability and underscores the importance of proactive maintenance efforts to safeguard against potential risks.
As a key component in the flood risk reduction infrastructure of Nebraska, the Rh&W Grazing Association Dam plays a crucial role in protecting the local community from potential disasters. With its strategic location and significant storage capacity, this earth dam serves as a bulwark against flooding events along Oak Creek. Moving forward, continued efforts to address the dam's poor condition assessment and ensure its structural integrity will be essential in maintaining the safety and resilience of the surrounding area in the face of changing climate patterns and water resource challenges.

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.
