Swan Creek 27 dam
Swan Creek 27
Swan Creek 27, located in SWANTON, Nebraska, is a key irrigation infrastructure managed by the USDA NRCS. This earth dam, completed in 1991, stands at a height of 37 feet and serves the primary purpose of irrigation, with a storage capacity of 2978 acre-feet and a normal storage level of 286 acre-feet. The dam spans 1157 feet in length and covers a surface area of 50 acres, contributing to the efficient management of water resources in the region.
Operated by the NE DNR, Swan Creek 27 is subject to state regulations and inspections, ensuring its structural integrity and compliance with safety standards. With a low hazard potential and satisfactory condition assessment, the dam plays a crucial role in water supply and management for the surrounding area. The dam's maximum discharge capacity of 3766 cubic feet per second further highlights its significance in mitigating potential flood risks and supporting agricultural activities.
As part of the larger water management system, Swan Creek 27 contributes to the overall sustainability and resilience of the region's water resources. With a strategic location in Jefferson County, Nebraska, and its affiliation with the Omaha District, the dam exemplifies the collaborative efforts between local government agencies and the USDA NRCS to safeguard water supplies and support agricultural needs in the area. The dam's consistent monitoring, regular inspections, and adherence to state regulations underscore its importance in addressing the water resource and climate challenges faced by the community.

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 Swan Creek 27
Where does the data for Swan Creek 27 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.
