Greensburg Upland Reservoir dam
Greensburg Upland Reservoir
Greensburg Upland Reservoir, located in Decatur, Indiana, is a vital water supply source designed by Samuel L. 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.

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.
- 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.
- 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.
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, environmental 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.

About Greensburg Upland Reservoir
Where does the data for Greensburg Upland Reservoir come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
