Cromwell Grade Stabilization Dam dam
Cromwell Grade Stabilization Dam
The Cromwell Grade Stabilization Dam, located in Nance County, Nebraska, is a privately owned structure designed by the USDA NRCS to address flood risk reduction and other purposes. Completed in 1991, this earth dam stands at 34 feet tall with a hydraulic height of 29 feet and a structural height of 40 feet. It spans 620 feet in length and has a storage capacity of 507 acre-feet, serving a drainage area of 2.8 square miles along TR-Skedee Creek.
Managed by the Nebraska Department of Natural Resources, the Cromwell Dam is regularly inspected and deemed to have a low hazard potential with a fair condition assessment. The last inspection was conducted in May 2019, with an inspection frequency of every five years. Despite its modest hazard potential, the dam plays a crucial role in mitigating flood risks and maintaining water resources in the area. The dam's operations contribute to the overall resilience of the region's water infrastructure and highlight the importance of effective dam management in the face of changing climate patterns.
The Cromwell Grade Stabilization Dam stands as a testament to the collaborative efforts between private owners, government agencies, and designers in safeguarding communities and ecosystems against potential water-related hazards. Its construction by the Natural Resources Conservation Service underscores the commitment to sustainable water resource management in Nebraska. With its strategic location and design features, the dam serves as a critical piece of infrastructure that not only reduces flood risks but also contributes to the overall water security and climate resilience of 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 Cromwell Grade Stabilization Dam
Where does the data for Cromwell 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.
