Dd No 105 dam
Dd No 105
Dd No 105, also known as Allen Creek Watershed Site 105, is a local government-owned structure located in Lyon, Kansas, specifically in the city of EMPORIA. This flood risk reduction dam, designed by USDA NRCS, serves the primary purpose of mitigating potential flooding along the ALLEN CREEK-TR, with a hydraulic height of 20 feet and a structural height of 23 feet. The dam, classified as an Earth dam with a buttress core type, stands at a length of 1050 feet and has a maximum storage capacity of 174.2 acre-feet.
With a hazard potential rated as low and a condition assessment not yet rated, Dd No 105 plays a crucial role in managing water resources in the area. Although it has not been inspected since November 2008, the structure's moderate risk level underscores the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in flood risk reduction. Despite lacking specific risk management measures or emergency action plans, Dd No 105 remains a key asset in safeguarding the community from potential water-related disasters.
As part of the Kansas City District, this dam contributes to the overall water management strategy in the region, highlighting the collaborative efforts between federal and local government agencies in addressing water resource challenges. The structure's location, design, and storage capacity all play a significant role in shaping the local water landscape and demonstrate the importance of proactive infrastructure planning and maintenance for climate and water enthusiasts alike.

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 105
Where does the data for Dd No 105 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.
