Uecker Dam 1 dam
Uecker Dam 1
Uecker Dam 1, located in Norfolk, Nebraska, was completed in 1974 with a primary purpose of flood risk reduction along the TR-N FK ELKHORN RIVER. This privately owned earth dam stands at a height of 14.5 feet and has a hydraulic height of 14.08 feet, providing storage of up to 54 acre-feet of water. With a low hazard potential and satisfactory condition assessment as of its last inspection in 2016, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the Nebraska Department of Natural Resources, Uecker Dam 1 is subject to state regulations, inspections, and enforcement to ensure its continued safety and effectiveness. The dam's design includes a stone core and soil foundation, with a length of 650 feet and a surface area of 2.7 acres. Despite its relatively small drainage area of 0.63 square miles, the dam is capable of handling a maximum discharge of 213 cubic feet per second, minimizing the risk of downstream flooding during heavy rainfall events.
Congressional District 01, Nebraska, represented by Jeff Fortenberry, oversees Uecker Dam 1 and its operations within the Omaha District of the US Army Corps of Engineers. With its strategic location and vital role in flood risk reduction, this dam stands as a testament to effective water resource management and climate resilience efforts in the region.

About Uecker Dam 1
Where does the data for Uecker Dam 1 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 below 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.

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.
