Closser Lake Dam dam
Closser Lake Dam
Closser Lake Dam, also known as Leming and Robinson Dam, is a privately owned structure located in Decatur, Indiana. Built in 1974, this earth dam stands at a height of 43 feet and stretches 520 feet in length, creating a reservoir with a maximum storage capacity of 750 acre-feet. The primary purpose of this dam is for recreation, providing a surface area of 21.7 acres for water enthusiasts to enjoy various activities.
The dam is regulated by the Indiana Department of Natural Resources and undergoes regular inspections, with the most recent assessment in August 2020 rating its condition as fair. Despite being classified as having a high hazard potential, the risk assessment is moderate, indicating that risk management measures are in place. With its uncontrolled spillway and proximity to the Flatrock River tributary, Closser Lake Dam serves as both a recreational destination and a critical infrastructure for water resource management in the region.
Overall, Closser Lake Dam represents a significant engineering feat in balancing the needs of recreation and water management. Its location within the Louisville District and oversight by the state regulatory agency underscores the importance of this dam in maintaining water quality, flood control, and public safety in the surrounding area. For water resource and climate enthusiasts, Closser Lake Dam is a key landmark to study and appreciate the intersection of human development and environmental stewardship.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Closser Lake Dam
Where does the data for Closser Lake Dam 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.
