Summary
Built in 1974 by the USDA NRCS, this earth dam stands at a height of 19 feet and has a hydraulic height of 16 feet. With a storage capacity of 95 acre-feet, the dam serves to protect the surrounding area from potential flooding events.
Managed by the Nebraska Department of Natural Resources, Goodwin Dam has a low hazard potential and is in satisfactory condition as of the last inspection in June 2019. The dam is located on the TR-NIOBRARA RIVER, a tributary of the Niobrara River, and covers a surface area of 4 acres with a drainage area of 2.4 square miles. Despite its modest size, the dam plays a crucial role in mitigating flood risks in the region, showcasing the importance of water resource management in the face of changing climate patterns.
With its strategic location and effective design, Goodwin Dam serves as a key infrastructure for flood risk reduction in Cherry County. As climate change continues to impact water resources, the maintenance and upkeep of such structures become increasingly important to ensure the safety and security of local communities. The collaboration between private owners, government agencies, and designers like the USDA NRCS highlights the collective effort to preserve water resources and adapt to a changing climate landscape.

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.
