Frd No 31 dam
Frd No 31
Frd No 31, also known as Wakarusa Watershed Dam 31, is located in Eudora, Kansas, and is owned by the Local Government. This earth dam, designed by USDA NRCS, was completed in 1971 with a primary purpose of flood risk reduction. Standing at a height of 40.3 feet and a length of 1048 feet, the dam has a normal storage capacity of 86 acre-feet and serves the Wakarusa River watershed.
Managed by the Kansas Department of Agriculture, this dam is state-regulated and undergoes regular inspections to ensure its safety and functionality. The dam has a high hazard potential and is rated in fair condition, with a moderate risk assessment score of 3. In case of emergencies, there are currently no Emergency Action Plans (EAP) prepared, but the dam is equipped with an uncontrolled spillway with a width of 70 feet. With a drainage area of 1.45 square miles, Frd No 31 plays a crucial role in mitigating flood risks in the region and protecting the local community from potential water-related disasters.
Water resource and climate enthusiasts will find Frd No 31 to be a significant infrastructure in the Wakarusa River watershed, serving as a vital flood risk reduction measure in Douglas County, Kansas. With its moderate risk assessment and fair condition, ongoing inspections and maintenance are essential to ensure the dam's continued effectiveness. As part of the state-regulated water infrastructure, Frd No 31 highlights the importance of proactive monitoring and management of dams to safeguard communities and water resources from the impacts of flooding and water-related emergencies.

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 Frd No 31
Where does the data for Frd No 31 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.
