Truman Harless Lake Dam dam
Truman Harless Lake Dam
Truman Harless Lake Dam, located in Morgan, Indiana, is a privately owned structure that serves as a recreational space for water resource and climate enthusiasts. Completed in 1976, this earth dam stands at a height of 41 feet and has a length of 500 feet, creating a surface area of 2.7 acres and a storage capacity of 41 feet. Despite its low hazard potential, the dam is currently assessed to be in poor condition, with its last inspection conducted in 2016.
Situated on Sycamore Creek, Truman Harless Lake Dam is regulated by the Indiana Department of Natural Resources and complies with state permitting, inspection, and enforcement requirements. The dam lacks a spillway and outlet gates, posing a risk of high inundation in the event of a breach. While the dam's risk assessment is rated as high, it remains a popular spot for outdoor activities and wildlife observation, attracting visitors to its serene waters and surrounding natural beauty.
As stakeholders continue to monitor and assess the condition of Truman Harless Lake Dam, it serves as a vital resource for recreation in the area, offering opportunities for boating, fishing, and relaxation. With a focus on risk management measures and maintaining safety protocols, this dam stands as a unique blend of human engineering and natural beauty, making it a point of interest for water resource and climate enthusiasts 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.
Plan around the weather

About Truman Harless Lake Dam
Where does the data for Truman Harless 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 Low 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.
