Summary
The dam stands at a height of 39.7 feet and has a length of 813 feet, providing a storage capacity of 490 acre-feet. Despite its low hazard potential and moderate risk assessment rating, the dam has not been rated for its condition as of the last inspection in 2011.
Managed by the Kansas Department of Agriculture, Dd No 30 is subject to state regulation, permitting, inspection, and enforcement. The dam sits on an unnamed tributary and is part of the Rock Island District within the state. Although the dam does not have associated locks, gates, or spillways, it does have a maximum discharge capacity of 4,776 cubic feet per second. With a surface area of 12 acres and a drainage area of 1.46 square miles, the dam serves as a vital infrastructure for water resource management in the region.
Designed by King Engineering, Dd No 30 remains a crucial part of the local government's water resource infrastructure. With its structural integrity and low hazard potential, the dam plays a significant role in mitigating flood risks and managing water supply in the area. As climate change continues to impact water resources, the proper maintenance and assessment of dams like Dd No 30 are essential for ensuring the safety and sustainability of water infrastructure 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.
