Dd No 102 dam
Dd No 102
Dd No 102, located in Lyon County, Kansas, is a vital earth dam designed for flood risk reduction on Duck Creek. Completed in 2001, this dam stands at a height of 30 feet and spans a length of 1200 feet, providing maximum storage of 709.3 acre-feet and normal storage of 79.74 acre-feet. With a low hazard potential and satisfactory condition assessment, Dd No 102 serves as a crucial infrastructure to manage the surface area of 18.8 acres and drainage area of 1.96 square miles.
Managed by the local government and regulated by the Kansas Department of Agriculture, Dd No 102 has been inspected periodically to ensure its reliability and safety. Despite its uncontrolled spillway type, this dam boasts a spillway width of 100 feet and a maximum discharge capacity of 1837.3 cubic feet per second. With no associated locks and a moderate risk assessment rating of 3, Dd No 102 continues to play a pivotal role in mitigating flood risks and protecting the surrounding community in Reading, Kansas.
As an essential component of the flood risk reduction strategy in the area, Dd No 102 remains a key piece of infrastructure that contributes to the overall water resource management efforts in Lyon County. With its strategic location on Duck Creek and efficient design, this earth dam stands as a testament to effective water resource management and climate resilience in the region.

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 102
Where does the data for Dd No 102 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.
