Dd No 124 dam
Dd No 124
Dd No 124, also known as Pony Creek Joint Dist No 78 Site 124, is a local government-owned earth dam located in Brown, Kansas. Designed by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Pony Creek-TR river. With a height of 28 feet and a length of 785 feet, it provides a storage capacity of 114.4 acre-feet and covers a surface area of 5.4 acres.
Despite being classified as low hazard potential and not rated for condition assessment, Dd No 124 plays a crucial role in mitigating flood risks in the area. The dam features an uncontrolled spillway with a width of 120 feet and has a moderate risk assessment rating of 3. While it has not been inspected since December 2007, the dam is still deemed to meet safety guidelines.
For water resource and climate enthusiasts, Dd No 124 offers valuable insight into the infrastructure and management of flood control systems in the region. Its location in Preston, Nebraska, and its association with the Natural Resources Conservation Service highlight the collaborative efforts involved in ensuring the safety and efficiency of water resource projects. With a focus on flood risk reduction, this dam stands as a testament to the importance of proactive measures in safeguarding communities from natural disasters.
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 Dd No 124
Where does the data for Dd No 124 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.
