Snyder Dam 156 dam
Snyder Dam 156
Snyder Dam 156, located in Omaha, Nebraska, is a crucial water resource structure owned by the local government. 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.
- 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.
- 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.
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, environmental 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.

About Snyder Dam 156
Where does the data for Snyder Dam 156 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
