Summary

This earth dam, completed in 1955, stands at a height of 30.3 feet and serves multiple purposes including flood risk reduction. With a storage capacity of 252.4 acre-feet and a drainage area of 2.17 square miles, Snyder Dam plays a vital role in managing water flow and protecting the surrounding area from potential flooding.

Despite its significance, Snyder Dam 156 is facing challenges as it has been assessed to be in poor condition with a significant hazard potential. The dam's last inspection in June 2020 revealed its deteriorating state, highlighting the need for urgent maintenance and possible risk management measures. With a poor condition assessment and a significant hazard potential, it is crucial for authorities to address these concerns promptly to ensure the safety and functionality of this important water structure.

For water resource and climate enthusiasts, Snyder Dam 156 serves as a focal point for understanding the complexities of managing water resources and mitigating flood risks. As a locally owned dam regulated by the Nebraska Department of Natural Resources, Snyder Dam highlights the ongoing efforts needed to maintain and improve critical infrastructure in the face of changing climate conditions. With its poor condition assessment and significant hazard potential, Snyder Dam 156 underscores the importance of proactive maintenance and risk management strategies to safeguard communities and ecosystems in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
