Summary
This private earth dam, completed in 1997, stands at a height of 27.4 feet with a hydraulic height of 22 feet and a structural height of 30 feet. It has a storage capacity of 93 acre-feet and a drainage area of 240 acres, making it an essential structure for managing water resources in the region.
With a low hazard potential and a moderate risk assessment rating, Noll Dam plays a crucial role in mitigating flood risks and ensuring water security in Chariton County, Missouri. Despite being uncontrolled, the spillway of the dam has a width of 16 feet to manage maximum discharges of up to 93 cubic feet per second. While the condition assessment of the dam is currently not rated, its design and construction meet regulatory standards, highlighting its importance in maintaining the safety and integrity of the surrounding area.
For water resource and climate enthusiasts, Noll Dam represents a significant infrastructure investment in water management and environmental protection. As a key structure in the Rock Island District, its presence helps to stabilize grades, control water flow, and reduce the risk of flooding in the region. With a focus on sustainability and safety, Noll Dam stands as a testament to the importance of proactive dam management and the crucial role these structures play in maintaining resilient water systems in the face of changing climate conditions.

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.
