Summary
Williams Dd No II, also known as Little Delaware Mission Creek FRS 2, is a flood risk reduction structure located in Horton, Kansas. Managed by the local government and designed by USDA NRCS, this dam is regulated by the Kansas Department of Agriculture and undergoes regular inspections and enforcement. Situated on Grasshopper Creek-TR, this buttress dam has a height of 32 feet and a hydraulic height of 29 feet, providing a storage capacity of 307 acre-feet.
With a low hazard potential and a condition assessment of "Not Rated," W.G. Williams Dd No II serves as a crucial infrastructure for managing flood risks in the area. The structure boasts a spillway width of 84 feet and is equipped with outlet gates for controlled water release. While the dam's exact construction date and volume are unspecified, its primary purpose remains flood risk reduction, aligning with its core function since its inception.
As an integral part of the water resource management system in Brown County, Kansas, W.G. Williams Dd No II plays a vital role in safeguarding the surrounding community from potential flooding events. With its state-regulated status and adherence to inspection and enforcement protocols, this dam stands as a testament to effective collaboration between local government entities and federal agencies like the Natural Resources Conservation Service.

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.
