Summary
Designed by USDA NRCS, this earth dam with a buttress core stands at a height of 25 feet, serving primarily for debris control along Grasshopper Creek. With a storage capacity of 100 acre-feet and a surface area of 3.99 acres, Gsd No 26 plays a crucial role in managing water resources in the region.
Despite its low hazard potential and moderate risk assessment, Gsd No 26 has not been rated for its condition assessment. The dam, with a maximum discharge of 740 cubic feet per second, features an uncontrolled spillway and lacks outlet gates. While it has not undergone recent inspections or maintenance, this structure remains vital for flood control and water management in the area. For water resource and climate enthusiasts, Gsd No 26 offers a fascinating insight into the infrastructure and management of water resources in Brown County, Kansas.
As an integral part of the local water management system, Gsd No 26 contributes to the overall resilience and sustainability of the region. With its strategic location and design, this dam showcases the importance of debris control and flood prevention in protecting communities and ecosystems along Grasshopper Creek. For those interested in the intersection of water resources, climate change, and infrastructure development, Gsd No 26 provides a compelling case study of how human intervention can shape and safeguard our waterways for future generations.

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.
