Summary
Wilbur Naylor and completed in 1992 to serve as a crucial flood risk reduction structure along Webster Creek. With a height of 39 feet and a length of 1100 feet, this dam provides essential debris control and flood risk reduction, holding a normal storage capacity of 144 acre-feet and a maximum storage of 879.4 acre-feet. The dam's significant hazard potential and moderate risk assessment highlight its importance in mitigating potential flooding impacts in the Nemaha County region.
Managed by the Kansas Department of Agriculture, this dam is regulated, permitted, inspected, and enforced at the state level, ensuring its structural integrity and operational effectiveness. The uncontrolled spillway, with a width of 70 feet, aids in managing high discharges of up to 1645 cubic feet per second. Although the condition assessment is currently not rated, the dam undergoes inspections every five years to assess its functionality and safety. Additionally, the dam lacks outlet gates but plays a crucial role in protecting the surrounding area from flooding events.
Overall, Gs Dd 31-13 stands as a vital infrastructure piece in the flood risk reduction strategy for Nemaha County, Kansas. With its strategic location along Webster Creek and its capacity to control debris and manage floodwaters, this earth dam serves as a safeguard against potential inundation, ensuring the safety and wellbeing of local communities in the region. Its construction and regulation by state authorities highlight the proactive measures taken to address water resource management and climate resilience in the area.

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.
