Dd No 249 dam
Dd No 249
Dd No 249 is a local government-owned dam located in Dunlap, Kansas, along the Rock Creek. The primary purpose of this Earth dam, with a height of 22 feet and a length of 1300 feet, is flood risk reduction, also serving debris control purposes. The dam has a storage capacity of 196.15 acre-feet, with a normal storage of 31.22 acre-feet and a surface area of 8.83 acres. Despite being classified as having a low hazard potential, the dam is rated as having a moderate risk level.
Constructed by Martin & Assoc., White, Dd No 249 has no federal ownership or funding and is not state-regulated, permitted, inspected, or enforced. With no outlet gates or locks, and an uncontrolled spillway type with a width of 78 feet, the dam's condition is currently not rated, and it has not been assessed for emergency action plan (EAP) preparedness or risk management measures. However, the structure is located in Morris County, Kansas City District, with the nearest congressional representative being Roger W. Marshall (R).
For water resource and climate enthusiasts, Dd No 249 presents an intriguing case study of a locally-owned dam designed for flood risk reduction along Rock Creek in Kansas. Despite its low hazard potential, the dam's moderate risk level and lack of regulatory oversight raise questions about its long-term resilience and emergency preparedness. With no recent inspection or assessment data available, the condition of Dd No 249 remains unknown, highlighting the importance of regular monitoring and maintenance for critical infrastructure in the face of changing environmental conditions.
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 249
Where does the data for Dd No 249 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.
