Stamm Dam Reservoir Report
Nearby: Judy Dam 1417 Harmoney Dam
Last Updated: December 14, 2025
Stamm Dam, located in Buffalo County, Nebraska, is a private-owned earth dam that was completed in 1960 with a primary purpose of flood risk reduction along the TR-Wood River.

Summary
Standing at a height of 13.7 meters and stretching 215 meters in length, this structure holds a normal storage capacity of 21.4 million cubic meters and a maximum storage of 77.5 million cubic meters. Despite its low hazard potential, Stamm Dam has been assessed to be in poor condition, indicating a need for maintenance and potential upgrades to ensure its continued effectiveness in flood mitigation.
Managed by the Nebraska Department of Natural Resources, Stamm Dam is subject to state regulations, permitting, inspection, and enforcement to ensure its structural integrity and compliance with safety standards. While the dam has not undergone recent modifications or assessments such as an Emergency Action Plan (EAP) or risk assessment, its last inspection in March 2020 highlighted the need for improved maintenance and potential risk management measures. With the Congressional District 03 represented by Adrian Smith, stakeholders and enthusiasts of water resources and climate in the area may be interested in monitoring the future developments and upkeep of Stamm Dam to enhance its resilience in the face of changing climate patterns and increasing flood risks.

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.
