Summary
Completed in 1990, this private-owned Earth dam boasts a structural height of 23 feet and a storage capacity of 62 acre-feet. Situated on the Weldon River, the dam provides a surface area of 5 acres for outdoor enthusiasts to enjoy various water activities.
Despite its high hazard potential, Yowell Lake Dam has not been rated for its condition assessment, and there is no inspection frequency specified. With a normal storage capacity of 38 acre-feet, the dam serves as a vital component of the local water infrastructure, supporting the recreational needs of the community. The dam's proximity to the Rock Island District underscores the significance of its role in water resource management for the region.
For water resource and climate enthusiasts, Yowell Lake Dam represents a unique intersection of human intervention in natural ecosystems. As a private-owned structure with limited oversight from state regulatory agencies, the dam serves as a focal point for understanding the complexities of balancing recreation with environmental conservation. Its presence on the Weldon River not only provides a picturesque setting for outdoor activities but also highlights the need for sustainable water management practices in the face of changing climate patterns.

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.
