Summary
Situated in Lawrence County, Indiana, this dam serves a low hazard potential and is not currently rated for its condition. The dam's primary purpose and associated structures remain unspecified, but it plays a crucial role in managing water resources in the region.
Despite being a state-owned structure, Williams Dam (In-Channel) is not regulated or inspected by the state agency, showcasing its unique operational framework. With a maximum discharge capacity of 4800 cubic feet per second, the dam holds importance in flood control and water management efforts in the area. The last inspection of the dam took place in 2008, and its Emergency Action Plan status remains undisclosed, highlighting the need for updated risk assessment and management measures.
For water resource and climate enthusiasts, Williams Dam (In-Channel) presents an intriguing case study of a historic water infrastructure that continues to play a vital role in the region's water management practices. With its storage capacity, discharge capabilities, and low hazard potential, the dam signifies the intersection of engineering ingenuity and environmental stewardship. As discussions around dam safety and resilience gain momentum, understanding the nuances of structures like Williams Dam can provide valuable insights into sustainable water resource management strategies for the future.

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.
