Summary
Built in 1963 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction in the Euchre Creek watershed. With a height of 33 feet and a length of 700 feet, Gsd No 12 has a storage capacity of 338 acre-feet and a normal storage of 41.8 acre-feet, covering a surface area of 6.9 acres.
The dam is regulated by the Kansas Department of Agriculture and undergoes regular inspections, with the last one conducted in November 2015. Despite being classified as having a significant hazard potential, Gsd No 12 is currently in fair condition, with a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 50 feet and has no outlet gates. Its location in Brown County, Kansas, makes it a critical structure for managing water resources and protecting the surrounding area from flooding.
As a key component of the local flood risk reduction infrastructure, Gsd No 12 plays a crucial role in safeguarding the community against potential water-related disasters. With its design by the USDA NRCS and oversight by state regulatory agencies, this earth dam stands as a testament to collaborative efforts in water resource management. Its presence in the Walnut Creek watershed highlights the importance of sustainable water infrastructure for climate resilience and disaster preparedness in the region.

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.
