Summary
13, also known as Westwood Park Dam, is a vital water supply structure located in Henry, Indiana. Owned by the local government, this earth dam was completed in 1974 and stands at a height of 64 feet, with a hydraulic height of 61 feet. The dam has a storage capacity of 4,629 acre-feet, serving the purpose of water supply for the area.
Despite its importance, Upper Big Blue River Structure No. 13 is in poor condition, with a significant hazard potential. The last inspection in February 2018 revealed the dam's deteriorating state, prompting the need for urgent maintenance and rehabilitation. With a high risk assessment rating of 2, it is crucial for the responsible authorities to address the structural deficiencies and implement risk management measures to ensure the safety and functionality of the dam.
Given its critical role in water supply and the potential risks associated with its current condition, Upper Big Blue River Structure No. 13 requires immediate attention and investment to safeguard the community and the environment. As water resource and climate enthusiasts, it is essential to advocate for the necessary actions to protect this essential infrastructure and prevent any potential disasters that may arise from its deteriorating state.

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.
