Dd No 3-1b dam
Dd No 3-1b
Dd No 3-1b, also known as Pawnee Watershed Dam 3-1b, is a local government-owned structure located in Ford, Kansas, with the primary purpose of flood risk reduction. Built in 1974 by the USDA NRCS, this earth dam stands at a height of 42 feet and has a hydraulic height of 41 feet, serving to protect the surrounding area from potential flooding events. With a normal storage capacity of 70 acre-feet and a maximum discharge of 5,275 cubic feet per second, Dd No 3-1b plays a crucial role in managing water resources in the region.
Situated on Duck Creek-TR, this dam covers a surface area of 13.5 acres and has a drainage area of 7.14 square miles. Its uncontrolled spillway, 200 feet wide, helps regulate water flow during times of excess precipitation, ensuring the safety of downstream communities. Inspected every five years, Dd No 3-1b has been deemed to have a significant hazard potential but maintains a satisfactory condition assessment. With a risk assessment rating of moderate, efforts are in place to manage and mitigate any potential risks associated with the dam for the benefit of the local environment and community.
As part of the overall water resource management strategy in Kansas, Dd No 3-1b serves as a critical infrastructure for flood control and risk reduction. With the support of the Kansas Department of Agriculture and the USDA NRCS, this dam continues to play a vital role in safeguarding the area against flooding events. As climate change impacts intensify, structures like Dd No 3-1b become increasingly important in ensuring the resilience and sustainability of water resources in the region, highlighting the significance of ongoing monitoring, inspection, and maintenance efforts to protect both the dam and the communities it serves.

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 3-1b
Where does the data for Dd No 3-1b 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 Significant 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.
