Little Walnut Creek Conservancy District Structure #4 dam
Little Walnut Creek Conservancy District Structure #4
Little Walnut Creek Conservancy District Structure #4, also known as Glenn Flint Lake Dam, is a local government-owned structure located in Putnam, Indiana. Completed in 1976, this earth dam stands at a height of 66 feet and serves the primary purpose of flood risk reduction along Owl Creek. With a storage capacity of 15,844 acre-feet and a drainage area of 15.16 square miles, this dam plays a crucial role in managing water resources in the region.
The dam features a spillway width of 450 feet and is equipped with slide (sluice gate) outlet gates for water release. Despite being classified as having a high hazard potential, a recent inspection in April 2020 rated its overall condition as fair. The dam is regulated by the Indiana Department of Natural Resources and has state permitting, inspection, and enforcement in place to ensure its operational safety and compliance with regulations.
Water resource and climate enthusiasts will appreciate the role of Little Walnut Creek Conservancy District Structure #4 in mitigating flood risks and managing water flow in the area. Its strategic location, design, and storage capacity make it a key asset in safeguarding the surrounding communities from potential inundation events. With regular inspections and state oversight, this dam continues to serve its critical function in protecting the environment and public safety.

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 #4
Where does the data for Little Walnut Creek Conservancy District Structure #4 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.
