Summary
Designed by Mr. Wilbur Naylor, P.E., this structure stands at a height of 32.4 feet and has a length of 550 feet, providing a normal storage capacity of 34 acre-feet and a maximum storage of 115 acre-feet. With a surface area of 4.8 acres and a drainage area of 0.41 square miles, the dam plays a crucial role in managing water flow in the region.
Managed by the Kansas Department of Agriculture, this dam is state-regulated with permitting, inspection, and enforcement mechanisms in place to ensure its structural integrity and compliance with safety standards. Despite being classified as having a low hazard potential, the dam poses a moderate risk due to its condition assessment being rated as "Not Rated." With a maximum discharge capacity of 744 cubic feet per second and an uncontrolled spillway width of 40 feet, Gs Dd No 3-31 is equipped to handle potential flood events and debris control efficiently.
With a risk management plan in place, it is essential for water resource and climate enthusiasts to monitor the maintenance and performance of Gs Dd No 3-31 to mitigate any potential risks and ensure the continued protection of the surrounding areas from flooding and water-related 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.
