Arnold Lake Dam dam
Arnold Lake Dam
Arnold Lake Dam, also known as Linnemeier Lake Dam, is a private dam located in Monroe, Indiana, with a primary purpose of recreation. Designed by JOHN LOUDERMILK, this earthen dam stands at a height of 26 feet and spans 190 feet in length, with a storage capacity of 17 acre-feet. The dam is regulated by the Indiana Department of Natural Resources and undergoes regular state inspections and enforcement to ensure its structural integrity and safety.
Despite its significant hazard potential and poor condition assessment, Arnold Lake Dam continues to be a popular spot for outdoor enthusiasts seeking recreational activities. The dam features an uncontrolled spillway and has a surface area of 3.5 acres, serving as a picturesque backdrop for fishing, boating, and other water-based activities. While the dam's risk assessment is moderate, with a risk level of 3, it remains an essential part of Indiana's water resource infrastructure and contributes to the local ecosystem's health.
With its location in the Louisville District and under the ownership of a private entity, Arnold Lake Dam represents a unique blend of natural beauty and human-made engineering. While facing challenges in terms of its structural condition and hazard potential, the dam remains a vital component of the region's recreational offerings and serves as a reminder of the importance of balancing water resource management with environmental conservation efforts.

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 Arnold Lake Dam
Where does the data for Arnold 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 Significant 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.
