Summary
The dam stands at a height of 24 feet and has a length of 885 feet, creating a reservoir with a normal storage capacity of 103 acre-feet. The dam is situated on an unnamed tributary of Graham Creek, within the jurisdiction of the Indiana Department of Natural Resources.
Despite being designated as a significant hazard potential, the dam is currently in fair condition, as assessed in January 2014. It is subject to regular inspections by the state regulatory agency, with the last inspection conducted in March 2020. With a high risk assessment rating of 2, there is a need for ongoing risk management measures to ensure the safety and integrity of the dam for both the surrounding community and the environment.
With its picturesque location and recreational purpose, Broomsedge Lake Dam serves as a vital water resource for the area. As water resource and climate enthusiasts, it is important to stay informed about the condition of such infrastructure and support efforts to maintain and manage these structures for the benefit of all stakeholders involved.

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.
