Summary
Completed in 1977, this earth dam stands at a height of 37 feet and spans 536 feet in length, with a storage capacity of 194 acre-feet. Despite its relatively low hazard potential, the dam's condition assessment is rated as poor, highlighting the need for ongoing maintenance and potential upgrades to ensure its long-term safety and functionality.
Managed by the Nebraska Department of Natural Resources, Rowan Dam plays a crucial role in providing irrigation water for the surrounding area. With a normal storage capacity of 177 acre-feet and a maximum discharge of 112 cubic feet per second, the dam helps support agricultural activities in the region. However, its condition assessment and hazard potential underscore the importance of regular inspections and maintenance to mitigate any potential risks to downstream communities and infrastructure.
Located within Congressional District 03, Nebraska, Rowan Dam is subject to state regulations and inspections to ensure compliance with safety standards. The dam's status as a privately owned structure with a low hazard potential emphasizes the need for continued monitoring and upkeep to safeguard both the local water resources and the surrounding environment. As water resource and climate enthusiasts, understanding the importance of maintaining and improving infrastructure like Rowan Dam is key to ensuring sustainable water management practices for future generations.

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.
