Dd No A-1 dam
Dd No A-1
Dd No A-1, also known as Cimarron WS Dam A-1, is a vital water resource infrastructure located in Gray County, Kansas. Owned by the local government and regulated by the Kansas Department of Agriculture, this earth dam was completed in 1961 with the primary purpose of flood risk reduction along the Arkansas River. Standing at a height of 21.8 feet and a length of 1390 feet, Dd No A-1 has a storage capacity of 429 acre-feet and serves a drainage area of 1.59 square miles.
Despite its importance in flood control, Dd No A-1 is currently assessed to be in poor condition with a high hazard potential. The dam lacks outlet gates and has an uncontrolled spillway with a width of 100 feet. With a moderate risk rating, it is crucial for the local government to implement risk management measures and conduct regular inspections to ensure the safety and integrity of the structure. The dam's last inspection was conducted in March 2020, with a frequency of 3 years.
As climate change continues to impact water resources and infrastructure, maintaining and upgrading structures like Dd No A-1 becomes increasingly critical. With its strategic location and significant role in flood risk reduction, this dam serves as a reminder of the importance of proactive management and investment in sustainable water resource projects to adapt to changing environmental conditions and protect communities from potential disasters.

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 A-1
Where does the data for Dd No A-1 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 High 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.
