Summary
Standing at a height of 30 feet with a hydraulic height of 29 feet, this dam spans 343 feet in length and has a maximum storage capacity of 21 acre-feet. With a surface area of 8 acres and a drainage area of 120 acres, Neer Dam serves as a vital structure in managing water resources in the region.
Despite its low hazard potential, Neer Dam plays a crucial role in mitigating risks associated with moderate inundation. The dam features an uncontrolled spillway with a width of 10 feet, ensuring the safe discharge of excess water during heavy rainfall events. While the dam's condition remains unrated, its design and construction reflect a commitment to safety and efficiency. Neer Dam stands as a testament to responsible water resource management and climate resilience in the face of changing environmental conditions.
As water resource and climate enthusiasts, it is important to recognize the significance of structures like Neer Dam in safeguarding communities and ecosystems from the impacts of extreme weather events. By understanding the design, purpose, and functionality of dams like Neer, we can better appreciate the efforts made to balance water management needs with environmental conservation. Neer Dam stands as a reminder of the critical role that infrastructure plays in building resilience to climate change and ensuring the sustainable use of water resources for future generations.

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.
