Rex Moore Detention Dam dam
Rex Moore Detention Dam
Located in Decatur, Kansas, the Rex Moore Detention Dam is a private earth dam designed by the USDA NRCS and completed in 1971 for the primary purpose of flood risk reduction along the Beaver Creek-TR. Standing at a height of 30 feet with a length of 904 feet, the dam has a storage capacity of 201.47 acre-feet and a maximum discharge rate of 2760 cubic feet per second.
Managed by the Kansas Department of Agriculture, the dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, the dam has not been assessed for its condition but is considered to meet guidelines for emergency action plans. The spillway, with a width of 200 feet, is uncontrolled, and there are no outlet gates or associated structures.
For water resource and climate enthusiasts, the Rex Moore Detention Dam serves as a vital infrastructure for mitigating flood risks in the region. Its strategic location and design, in conjunction with state oversight and management, make it an essential asset for protecting the surrounding area from potential water-related disasters. The dam's historical significance and ongoing role in water management highlight the importance of sustainable infrastructure for adapting to changing climate conditions and enhancing water resource resilience.

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 Rex Moore Detention Dam
Where does the data for Rex Moore Detention Dam 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.
