Summary

Park Lake Dam, located in Union, Indiana, is a state-regulated structure on Silver Creek that serves primarily for recreation purposes. Built in 1949, this earth dam stands at 70 feet in height with a hydraulic height of 67 feet and a length of 600 feet. The dam has a storage capacity of 8,610 acre-feet and covers a surface area of 201 acres, with a maximum discharge capacity of 34,882 cubic feet per second.

Despite being classified as having a significant hazard potential, the dam's condition assessment is rated as fair. It is subject to regular state inspections and enforcement measures to ensure its safety and integrity. While it currently does not have a spillway, the dam is designed to manage water levels effectively for recreational activities and wildlife preservation in the surrounding area. The risk assessment for Whitewater St. Park Lake Dam is considered high, highlighting the importance of ongoing monitoring and maintenance efforts to prevent any potential threats to downstream communities and infrastructure.

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.
