Dd No 1 (Hamm-Nuttle) dam
Dd No 1 (Hamm-Nuttle)
Dd No 1 (Hamm-Nuttle) is a crucial flood risk reduction structure located in the Upper Walnut Watershed in Kansas. Built in 1978 by the USDA NRCS, this earth dam stands at a height of 28 feet and spans 1330 feet, with a storage capacity of 540 acre-feet. The dam plays a significant role in protecting the surrounding area from potential flooding events along the Walnut River, with a maximum discharge capacity of 298 cubic feet per second.
Owned and regulated by the local government and the Kansas Dept. of Agriculture, Dd No 1 is deemed to have a low hazard potential with a moderate risk assessment rating. Despite its importance in flood risk reduction, the dam's condition assessment remains unrated, highlighting the need for regular inspections and maintenance. The structure also lacks an Emergency Action Plan (EAP) and inundation maps, underscoring the importance of preparedness and risk management measures for water resource and climate enthusiasts in the region.
As a key piece of infrastructure in Butler County, Kansas, Dd No 1 serves as a vital component in the overall water resource management strategy for the area. With its strategic location and design, the dam not only provides flood protection but also contributes to the overall resilience of the local community in the face of changing climate patterns. Ensuring the continued safety and functionality of Dd No 1 will be essential in safeguarding the region's water resources and mitigating the impacts of climate-related events in the future.
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 1 (Hamm-Nuttle)
Where does the data for Dd No 1 (Hamm-Nuttle) 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.
