Raben Dam 2 dam
Raben Dam 2
Raben Dam 2 is a privately owned irrigation dam located in Sioux County, Nebraska. Constructed in 1951 by the USDA NRCS, this earth dam stands at a height of 30 feet and has a structural height of 30 feet as well. With a normal storage capacity of 100 acre-feet and a maximum storage capacity of 180 acre-feet, the dam serves the primary purpose of irrigation for agricultural activities in the area.
Although Raben Dam 2 has a low hazard potential, its condition assessment is listed as poor as of the last inspection in September 2019. The dam spans a length of 475 feet and is designed with stone core types and soil foundations. Despite its poor condition, the dam continues to provide vital water resources for the region, drawing from the TR-WHITEHEAD CREEK. It is regulated by the Nebraska Department of Natural Resources and undergoes regular state inspections, enforcement, and permitting processes to ensure its safety and functionality.
With a drainage area of 2.7 square miles and a maximum discharge capacity of 1500 cubic feet per second, Raben Dam 2 plays a crucial role in managing water resources for agriculture in the region. As a key element in the irrigation infrastructure, the dam's maintenance and upkeep are essential to sustainably support the needs of farmers and promote efficient water usage in the face of changing climate conditions. Efforts to improve the dam's condition and ensure its long-term reliability are crucial for safeguarding water resources and adapting to the challenges of a changing climate in the area.

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 Raben Dam 2
Where does the data for Raben Dam 2 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.
