South Branch 2-2 dam
South Branch 2-2
South Branch 2-2 is a local government-owned earth dam located in Burr, Nebraska, within the Otoe County. Constructed by the USDA NRCS in 1992, this structure serves primarily for flood risk reduction along the TR-S FK Little Nemaha River. With a height of 29 feet and a length of 935 feet, the dam has a storage capacity of 163 acre-feet and a drainage area of 0.7 square miles.
Managed by the Nebraska Department of Natural Resources, South Branch 2-2 has a low hazard potential and is in satisfactory condition based on a 2016 assessment. The dam has a hydraulic height of 27 feet and a structural height of 33 feet, providing essential protection to the surrounding area. Despite its critical purpose, the dam is currently not under the authority of any federal agency and has not undergone recent modifications or emergency action plan updates.
For water resource and climate enthusiasts, South Branch 2-2 serves as a vital infrastructure for flood control in the region, showcasing the collaborative effort between local and state agencies to ensure the safety and resilience of the community. With its stone core and soil foundation, this earth dam stands as a testament to the importance of sustainable water management practices in safeguarding against natural disasters and preserving the integrity of the Little Nemaha River watershed.
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 South Branch 2-2
Where does the data for South Branch 2-2 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.
