Summary
The dam stands at a height of 22 feet and stretches 406 feet in length, with a storage capacity of 52 acre-feet. With a surface area of 3.4 acres and a drainage area of 0.15 square miles, the dam serves as a crucial resource for the surrounding area in terms of water management and conservation.
Managed by the Iowa Department of Natural Resources, the Upper Locust Creek Watershed Site L-23 has been designated as a low hazard potential structure with a moderate risk assessment score of 3. While the dam has not been inspected or rated for its condition, it is nonetheless equipped with an uncontrolled spillway system. The site's location near the TR-West Fork Locust Creek and its role in safeguarding against potential inundation make it an essential component of the local water resource infrastructure, highlighting its importance for both water resource management and climate resilience efforts in the region.
With its strategic placement in West Liberty, MO, the Upper Locust Creek Watershed Site L-23 serves as a critical point of contact for emergency management and risk mitigation. Although not currently rated for its condition, the dam's construction and design by the USDA NRCS underscore its importance in providing essential services such as flood risk reduction and fire protection. As climate change continues to impact water resources, the site's role in water management and conservation efforts becomes increasingly crucial for ensuring the sustainability and resilience of the surrounding ecosystem.

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.
