Summary
11-13 is a local government-owned earth dam designed by the USDA NRCS and completed in 2000 for debris control purposes. Standing at 41 feet high and spanning 880 feet in length, this structure plays a crucial role in managing the South Fork Wolf River-TR, with a storage capacity of 754 acre-feet and a drainage area of 2.24 square miles. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition and lacks an emergency action plan, raising concerns for its long-term resilience.
Managed by the Kansas Department of Agriculture, Gsd No. 11-13 is subject to state regulation, permitting, inspection, and enforcement, ensuring its compliance with safety standards. With a spillway width of 40 feet and a maximum discharge capacity of 1372 cubic feet per second, this dam is equipped to handle potential flood events and protect downstream communities. However, the absence of outlet gates and a documented condition assessment highlights the need for proactive monitoring and maintenance to safeguard its structural integrity and functionality.
As water resource and climate enthusiasts, it is essential to recognize the critical role of infrastructure like Gsd No. 11-13 in enhancing water management and mitigating environmental risks. By advocating for regular inspections, emergency preparedness, and long-term maintenance plans, stakeholders can contribute to the sustainability and resilience of this vital earth dam, ensuring its effectiveness in safeguarding the local ecosystem and communities against potential hazards.

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.
