South Fork 2-10 dam
South Fork 2-10
South Fork 2-10 is a vital structure located in Pawnee, Nebraska, managed by the local government and designed by the USDA NRCS. This earth dam, completed in 1978, serves the primary purpose of flood risk reduction along the TR-LORES BR S FK BIG NEMAHA R River. With a height of 32 feet and a length of 802 feet, it provides storage capacity of 123 acre-feet and covers a surface area of 9 acres, benefiting a drainage area of 0.4 square miles.
Maintained by the Nebraska Department of Natural Resources, South Fork 2-10 has a low hazard potential and is in satisfactory condition as of the last inspection in June 2016. It stands as a key component in the local water resource management system, ensuring the safety and well-being of the surrounding community. Despite being a relatively small structure, its significance lies in its role in mitigating flood risks and safeguarding the local area from potential water-related disasters.
This dam, with its stone core and soil foundation, showcases the collaborative efforts between local and federal agencies in safeguarding water resources in the region. With state regulatory agencies overseeing its operation and enforcement, South Fork 2-10 stands as a testament to effective water resource management practices. As climate change continues to impact water resources, structures like South Fork 2-10 play a crucial role in adapting to and mitigating the effects of a changing climate on water availability and quality 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 South Fork 2-10
Where does the data for South Fork 2-10 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.
