Summary
This earth dam stands at a height of 30 feet, with a hydraulic height of 25 feet and a length of 1100 feet. It has a normal storage capacity of 9.66 acre-feet, serving a drainage area of 0.74 square miles in the Switzler Creek Watershed.
Situated in the city of Burlingame, Jennings Dd No 4 is regulated by the Kansas Department of Agriculture and undergoes state permitting, inspection, and enforcement. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in managing water resources and mitigating potential flood risks in the area. The dam's uncontrolled spillway, with a width of 80 feet, ensures that excess water can safely flow out, protecting the surrounding community from inundation during heavy rainfall events.
As part of its risk management measures, Jennings Dd No 4 does not have an Emergency Action Plan (EAP) prepared or updated, highlighting the need for ongoing monitoring and planning to ensure the safety and functionality of this essential water infrastructure. With its strategic location and design, this dam serves as a key asset in safeguarding the local environment and residents from the impacts of extreme weather events and changing climate patterns in the region.

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.
