Summary
Built in 1992 by designer G. Maxwell, this dam serves primarily for flood risk reduction and debris control purposes. It stands at a height of 26 feet and stretches 450 feet in length, with a storage capacity of 67.55 acre-feet and a drainage area of 0.25 square miles.
Despite being categorized as having a low hazard potential, Dd No 6-35a plays a crucial role in managing water resources in the area. With a moderate risk assessment score of 3, the dam has not been inspected or rated for its current condition. It does not have outlet gates or locks, but features an uncontrolled spillway with a width of 40 feet. The dam's location and design make it a key component in the region's water resource and climate management efforts.
Overall, Dd No 6-35a (Stedman-Shumaker) stands as a notable infrastructure for flood risk reduction along Wolfley Creek in Kansas. As a local government-owned structure, its importance lies in its ability to control debris and manage floodwaters effectively. With its design and purpose, this earth dam serves as a significant asset in the region's water resource and climate resilience strategies.

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.
