Summary
The dam, designed by USDA NRCS, serves the primary purpose of debris control and flood risk reduction. With a dam height of 37.5 feet and a length of 950 feet, Gs Dd No B-33 (Gc 22) has a normal storage capacity of 97 acre-feet and a maximum storage capacity of 827 acre-feet, making it a crucial infrastructure for water resource management in the area.
This earth dam, with a buttress core type, has a spillway width of 60 feet and a maximum discharge capacity of 1834 cubic feet per second. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level. The dam is regulated by the Kansas Department of Agriculture and undergoes state permitting, inspection, and enforcement to ensure its structural integrity and safety. As a key component in managing flood risks and debris control along Coal Creek, Gs Dd No B-33 (Gc 22) plays a vital role in protecting the local community and surrounding areas from potential water-related disasters.
This dam, while not rated for its condition assessment, is a critical piece of infrastructure in the region, serving as a buffer against potential flooding events. With its controlled spillway and state-regulated operations, Gs Dd No B-33 (Gc 22) showcases the collaborative efforts between local government and federal agencies, such as the Natural Resources Conservation Service, in ensuring water resource management and climate resilience. Its location, design, and purpose underscore the importance of sustainable water infrastructure in safeguarding communities and ecosystems against the impacts of a changing climate.

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.
