Summary
Built in 2005 by the USDA NRCS, this earth dam stands at a height of 28.6 feet with a structural height of 32 feet, offering a storage capacity of 67.9 acre-feet to manage potential flooding in the area. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in protecting the surrounding Sullivan County from the impacts of extreme weather events.
Despite not being state-regulated or inspected, Upper Locust Creek W-190 serves as a reliable line of defense against flooding, with a spillway width of 20 feet to manage excess water flow. The dam's primary purpose is flood risk reduction, reflecting its importance in safeguarding local communities and infrastructure from water-related disasters. With a drainage area of 357 square miles and a maximum discharge of 117.4 cubic feet per second, this structure effectively mitigates the potential impacts of heavy rainfall and extreme weather events on the region.
Overall, Upper Locust Creek W-190 stands as a testament to the collaborative efforts between local government and the USDA NRCS in addressing water resource and climate challenges. As a key component of the flood risk reduction infrastructure in Sullivan County, this earth dam exemplifies the importance of proactive measures in protecting communities and natural resources from the growing threats of climate change and extreme weather events.

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.
