Summary
Built in 1995 by designer Wilbur Naylor, this dam stands at a height of 28.6 feet and has a storage capacity of 72.45 acre-feet. With a spillway width of 30 feet and a low hazard potential, this structure plays a vital role in managing water resources in the region.
Despite being unregulated by the state and with no associated structures, Gs Dd No 9 has a moderate risk assessment rating of 3. While its condition is currently not rated, the dam has not been inspected since February 1995. Although it has not undergone any modifications or improvements in recent years, it serves as a critical part of the local water infrastructure, contributing to flood control and water supply management efforts in the area.
As a key element in the water management system of Brown, Kansas, Gs Dd No 9 provides important data for water resource and climate enthusiasts to study and analyze. With its unique design features and moderate risk assessment, this earth dam showcases the intersection of engineering, environmental science, and public policy in ensuring the safety and sustainability of water resources 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.
