Little Walnut Creek Conservancy District - Structure 3 dam
Little Walnut Creek Conservancy District - Structure 3
Located in Putnam, Indiana, the Little Walnut Creek Conservancy District - Structure 3, also known as Anderson Lake, plays a crucial role in flood risk reduction along Leatherman Creek. Built in 1971, this earth dam stands at a height of 34 feet and stretches 1500 feet in length. With a storage capacity of 820 acre-feet and a normal storage level of 77 acre-feet, this structure serves as a vital component in managing water flow and mitigating flood hazards in the area.
Managed by the Local Government, specifically the Indiana Department of Natural Resources, this dam is regularly inspected and maintained to ensure its structural integrity. Despite being classified as having a high hazard potential, its condition is assessed as fair, indicating ongoing efforts to uphold safety standards. With a spillway width of 150 feet and a maximum discharge capacity of 4550 cubic feet per second, this dam is equipped to handle significant water flow during extreme weather events.
For water resource and climate enthusiasts, the Little Walnut Creek Conservancy District - Structure 3 stands as a testament to effective flood risk reduction infrastructure in Indiana. With its strategic location and design features, this dam plays a critical role in safeguarding communities along Leatherman Creek from potential flooding events. As efforts continue to monitor and maintain this structure, its importance in water resource management and climate resilience remains a key focus for local authorities and environmental stakeholders alike.

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 Little Walnut Creek Conservancy District - Structure 3
Where does the data for Little Walnut Creek Conservancy District - Structure 3 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.
