Summary
Built in 1978 by the USDA NRCS, this earth dam stands at 24 feet high and stretches 1475 feet in length. With a maximum storage capacity of 299 acre-feet and a normal storage of 53 acre-feet, Dd No 2 plays a crucial role in managing floodwaters in the region. The dam is state-regulated and undergoes regular inspection, enforcement, and permitting by the Kansas Department of Agriculture.
Despite its low hazard potential, Dd No 2 (Wells) is deemed to have a moderate risk level based on a risk assessment rating of 3. The structure does not have an Emergency Action Plan in place, and its condition assessment is currently not rated. The dam is not equipped with outlet gates, and its spillway is classified as uncontrolled with a width of 124 feet. While the risk management measures for the dam are not specified, its overall risk profile suggests the need for continued monitoring and maintenance to ensure its effectiveness in flood risk reduction for the community.
In conclusion, Dd No 2 (Wells) serves as a vital infrastructure for flood control in Woodson County, Kansas. Managed by the local government and designed by the Natural Resources Conservation Service, this earth dam provides essential protection against potential flooding events along the South Big Creek. With a focus on flood risk reduction, Dd No 2 plays a significant role in safeguarding the surrounding area from the impacts of extreme weather events and ensuring the safety and well-being of the local residents.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
