Summary
Completed in 2001, this dam stands at a height of 27 feet and has a hydraulic height of 26 feet, with a maximum storage capacity of 88 acre-feet and a normal storage capacity of 25 acre-feet. With a surface area of 11 acres and a drainage area of 896 square miles, the dam plays a crucial role in managing water resources in the area.
The dam on Upper Locust Creek serves multiple purposes including fire protection, stock and small fish pond, fish and wildlife pond, in addition to flood risk reduction. It has a low hazard potential and a moderate risk assessment rating of 3. Despite not being state-regulated or inspected, the dam's condition is not rated and its emergency action plan status is unclear. With a spillway width of 20 feet and uncontrolled outlet gates, the dam provides essential water management functions while also supporting the local ecosystem and community.
Located in the Rock Island District, Upper Locust Creek L-94 is an integral part of the water infrastructure in the region, contributing to both flood protection and environmental conservation efforts. With its strategic design and construction by the Natural Resources Conservation Service, this dam serves as a key asset in water resource management, showcasing the importance of sustainable infrastructure for climate resilience and community safety in the face of changing weather patterns and increasing water-related challenges.

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.
