Summary
Designed by the USDA NRCS and completed in 2005, this earth-type dam stands at a height of 30 feet, with a dam length of 490 feet and a storage capacity of 61.2 acre-feet. With a primary purpose of flood risk reduction, the dam serves to protect the surrounding area from potential water hazards.
Situated along the TR-West Locust Creek, Upper Locust Creek W-188 plays a crucial role in managing water resources in the region. With a drainage area of 220 square miles and a maximum discharge of 111.5 cubic feet per second, the dam provides essential flood control measures to safeguard the community. Despite its low hazard potential, the dam's risk assessment indicates a moderate level of risk (3), highlighting the importance of continued monitoring and maintenance to ensure its effectiveness in mitigating flood impacts.
Owned by the local government and operated by the Natural Resources Conservation Service, Upper Locust Creek W-188 represents a collaborative effort to address water resource challenges in the area. While not currently regulated or inspected by the state, the dam stands as a testament to proactive flood risk management and the ongoing commitment to protecting the community from water-related threats. As water resource and climate enthusiasts, understanding the significance of structures like Upper Locust Creek W-188 is essential in promoting sustainable water management practices and resilience to changing environmental 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.
