Summary

Dam (In-Channel) is a privately owned structure located along the East Fork White River in Jackson, Indiana. The dam stands at a height of 9 feet and stretches 360 feet in length, providing storage capacity of 620 acre-feet. With a surface area of 137.7 acres and a drainage area of 2336.82 square miles, this dam plays a crucial role in water resource management in the region.

Although the dam's hazard potential is categorized as low and its condition assessment as fair, there is a high risk (rating of 2) associated with the structure. The last inspection was conducted in March 2016, with a frequency of every 5 years. Despite meeting state regulations for inspection, permitting, and enforcement, the dam's risk management measures and emergency preparedness appear to be lacking information. Further attention to these aspects may be necessary to ensure the safety and sustainability of the dam for the surrounding community and environment.

As a key feature along the East Fork White River, Seymour Water Co. Dam (In-Channel) serves as a vital component of the local water resource infrastructure in Indiana. With its significant storage capacity and strategic location, the dam plays a crucial role in managing water flow and storage in the region. However, the high risk associated with the dam highlights the importance of ongoing monitoring, maintenance, and emergency preparedness to safeguard against potential hazards and ensure the continued effectiveness of this essential water management structure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
