Gerdes Smith Grade Stabilization Dam dam
Gerdes Smith Grade Stabilization Dam
Located in Nemaha, Nebraska, the Gerdes Smith Grade Stabilization Dam is a vital infrastructure designed by the USDA NRCS to manage flood risk along the TR-Muddy Creek. Completed in 1980, this earth dam stands at a height of 31 feet and extends for 466 feet, providing a significant storage capacity of 61 acre-feet. With a primary purpose of flood risk reduction, the dam also serves other essential functions for the local community.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, the Gerdes Smith Grade Stabilization Dam is in satisfactory condition with low hazard potential. Its last inspection in March 2020 confirmed its structural integrity, ensuring the safety of nearby residents and infrastructure. With a drainage area of 0.3 square miles and a maximum discharge capacity of 200 cubic feet per second, this dam plays a crucial role in water resource management in the region.
As an essential piece of infrastructure in the Omaha District, the Gerdes Smith Grade Stabilization Dam not only provides flood protection but also contributes to the overall water security of the area. With its strategic location and effective design, this dam stands as a key asset in safeguarding against the impacts of climate change and ensuring the sustainable management of water resources in Nemaha, Nebraska.
Dam data reference
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 Gerdes Smith Grade Stabilization Dam
Where does the data for Gerdes Smith Grade Stabilization Dam 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 Low 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.
