Dd No 108 dam
Dd No 108
Dd No 108, also known as Jacobs Phenis Creek WS Site 108, is a vital earth dam located in Lyon, Kansas, specifically in the city of Emporia. Constructed in 1980 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Cottonwood River-TR. With a structural height of 25 feet and a length of 1355 feet, Dd No 108 has a storage capacity of 216.6 acre-feet, providing essential protection to the surrounding area.
Managed by the Kansas Department of Agriculture, Dd No 108 is regulated and inspected regularly to ensure its functionality in times of need. With a low hazard potential and a moderate risk assessment rating, this dam stands ready to mitigate flood risks and protect the local community. Although its condition assessment is currently not rated, the dam's design and construction align with best practices for water resource management and climate resilience.
As a key piece of infrastructure in the region, Dd No 108 plays a crucial role in safeguarding against potential flooding events and ensuring the safety of nearby residents. With its uncontrolled spillway and strategic location, this dam exemplifies the importance of proactive flood risk reduction measures in the face of changing climate patterns. For water resource and climate enthusiasts, Dd No 108 serves as a noteworthy example of effective dam management and the critical role it plays in protecting communities and enhancing environmental 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 Dd No 108
Where does the data for Dd No 108 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.
