Summary
Completed in 1966, this earth dam stands at a height of 21 feet and spans a length of 416 feet. With a primary purpose classified as "Other," the dam serves to provide water storage and management for the surrounding area. Despite its low hazard potential, the dam's condition assessment is deemed "poor," highlighting the need for maintenance and potential improvements.
Managed under the jurisdiction of the Nebraska Department of Natural Resources (DNR), Dinsdale Lagoon Dam undergoes regular state inspection, enforcement, and permitting processes to ensure its safety and compliance. The dam's storage capacity reaches a maximum of 77 acre-feet, with a normal storage level around 56 acre-feet. The dam also covers a surface area of 10 acres and drains a 0.2 square mile watershed, contributing to water resource management in the region.
While Dinsdale Lagoon Dam has a history of modification in 2001 for hydraulic purposes, its risk assessment, emergency action plan, and inundation maps are currently lacking detailed preparation. As water enthusiasts and climate advocates continue to monitor and advocate for the sustainable management of water resources, the condition and maintenance of structures like Dinsdale Lagoon Dam play a crucial role in ensuring the safety and resilience of local communities in the face of changing climate conditions.

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.
