Summary
Built in 1967, this earth dam stands at a height of 19 feet and spans 300 feet in length, providing storage capacity of 181 acre-feet and serving a drainage area of 11.4 square miles. With a low hazard potential and no specific condition rating, Long Dam is regulated and inspected by the Nebraska Department of Natural Resources to ensure its structural integrity and functionality.
The dam's primary purpose is flood risk reduction, with a normal storage capacity of 68 acre-feet and a maximum discharge rate of 1403 cubic feet per second. While Long Dam does not have a designated spillway type or outlet gates, it is equipped to handle potential emergencies with a 5-year inspection frequency. The surrounding area covers 16 acres and is under the jurisdiction of the state, with state permitting, inspection, and enforcement protocols in place to maintain its operational safety and efficiency. Congressman Adrian Smith represents this district where the dam is situated.
Water resource and climate enthusiasts interested in Long Dam can appreciate its role in mitigating flood risks and managing water flow along the TR-Lodgepole Creek. This structure, despite its low hazard potential, plays a crucial part in the local ecosystem by providing storage capacity and drainage capabilities for the surrounding area. As a state-regulated and inspected dam, Long Dam demonstrates a commitment to ensuring the safety and functionality of water infrastructures in Nebraska, contributing to overall water resource management efforts in the region.

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.
