Elrod Lake Dam dam
Elrod Lake Dam
Located in Zionsville, Indiana, Elrod Lake Dam is a privately owned structure designed by the USDA NRCS and regulated by the Indiana Department of Natural Resources. Completed in 1967, this earth dam stands at 25 feet in height and serves primarily for recreational purposes, with a storage capacity of 100 acre-feet. The dam spans 380 feet in length and is situated on Jackson Run, offering a surface area of 5.8 acres for water enthusiasts to explore.
With a low hazard potential and fair condition assessment, Elrod Lake Dam has a moderate risk level and is inspected every five years to ensure its structural integrity. The dam features an uncontrolled spillway and has a maximum discharge capacity of 404 cubic feet per second. While there are no outlet gates, the dam's foundations consist of soil and core types of stone, providing stability for its operations. The surrounding area offers a serene environment for outdoor activities and wildlife observation, making it a popular destination for both locals and visitors alike.
Elrod Lake Dam's presence on the tranquil waters of Jackson Run in Boone County, Indiana, not only enhances the natural landscape but also provides a safe and enjoyable recreational space for water resource and climate enthusiasts. With its strategic location and well-maintained infrastructure, the dam stands as a testament to the importance of sustainable water management practices while catering to the diverse needs of the community. As a key element in the region's water resource infrastructure, Elrod Lake Dam continues to play a vital role in supporting both environmental conservation and outdoor recreation opportunities.

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 Elrod Lake Dam
Where does the data for Elrod 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.
