Horseshoe Lake Dam dam
Horseshoe Lake Dam
Horseshoe Lake Dam, also known as Jean Williamson Lake Dam, is a private earth dam located in Bartholomew County, Indiana. Built in 1965 by the USDA NRCS, this dam stands at a height of 32 feet and spans a length of 610 feet, creating a reservoir with a storage capacity of 94 acre-feet. The primary purpose of this structure is for recreation, providing a surface area of 6.9 acres for water enthusiasts to enjoy.
Managed by the Indiana Department of Natural Resources, Horseshoe Lake Dam is regulated, inspected, and enforced for safety measures. The dam's spillway, with a width of 250 feet, is uncontrolled and can discharge a maximum of 558 cubic feet per second. Despite being classified as having a high hazard potential, the dam's condition assessment in 2006 rated it as fair. Regular inspections occur every two years to ensure its structural integrity and overall safety.
With its picturesque location along an unnamed tributary of East Fork Salt Creek, Horseshoe Lake Dam serves as a vital recreational resource for the community of Taggart. As climate change continues to impact water resources, the management and upkeep of dams like Horseshoe Lake Dam will be crucial in maintaining safe and sustainable water infrastructure for future generations of climate and water resource enthusiasts to enjoy.

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 Horseshoe Lake Dam
Where does the data for Horseshoe 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.
