Summary
Built in 1977, this earth dam stands at a height of 22 feet with a maximum storage capacity of 50 acre-feet. The dam also offers fire protection, stock, or small fish pond, fish and wildlife pond, grade stabilization, and recreational benefits to the local community.
With a spillway width of 41 feet and a low hazard potential, the Newland Sec-20 Lake Dam is categorized as having a moderate risk level. Despite its condition being labeled as "Not Rated," the dam's design and construction reflect a commitment to public safety and flood control measures. The dam's location in AULLVILLE, under the jurisdiction of the Kansas City District, makes it an essential component of the local water resource infrastructure.
As water resource and climate enthusiasts, understanding the characteristics and purposes of dams like Newland Sec-20 Lake Dam provides insight into how these structures play a crucial role in managing water resources, mitigating flood risks, and supporting various ecological functions. The dam's presence highlights the importance of sustainable infrastructure development and emergency preparedness in safeguarding communities and the environment against water-related hazards.

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.
