Summary
Moore & Associates, Inc. The reservoir, completed in 1990, has a dam height of 35 feet and a storage capacity of 1365 acre-feet. It sits on Clifty Creek and serves as a controlled spillway with a surface area of 36 acres. The dam's primary purpose is to provide water supply to the surrounding area, with a fair condition assessment as of April 2005.
This reservoir is regulated by the Indiana Department of Natural Resources and undergoes regular inspections to ensure its safety. With a high hazard potential and a very high risk assessment rating, emergency preparedness is crucial for this water resource. The reservoir's condition is closely monitored, with the last inspection conducted in September 2020. Despite its fair condition, the reservoir plays a crucial role in water supply for the region and is a key component of the local water infrastructure.
Greensburg Upland Reservoir's location in Decatur, Indiana, highlights its importance as a public utility serving the community's water needs. Although it has a high hazard potential, the reservoir's controlled spillway and regulated maintenance ensure its continued operation. With a history of providing reliable water supply since its completion in 1990, this Earth-type dam on Clifty Creek is a key feature of the region's water infrastructure, contributing to the resilience of the local water resource system.

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.
