Van Rooy Lake Dam dam
Van Rooy Lake Dam
Van Rooy Lake Dam, also known as Jenks Lake Dam, is a privately owned structure located in Morgan, Indiana. Completed in 1963, this earth dam stands at a height of 36 feet and spans a length of 330 feet, creating a storage capacity of 68 acre-feet. The dam regulates an unnamed tributary of the South Prong Stotts Creek and is under the regulatory oversight of the Indiana Department of Natural Resources.
Despite its age, Van Rooy Lake Dam poses a high hazard potential due to its poor condition assessment in 2008. The dam has a moderate risk assessment rating of 3, indicating the need for ongoing risk management measures to ensure public safety and environmental protection. The last inspection in June 2017 highlighted the need for frequent monitoring and potential emergency action planning to mitigate any safety concerns.
Water resource and climate enthusiasts should take note of Van Rooy Lake Dam as a critical infrastructure contributing to the water management system in Indiana. Its structural integrity and ongoing maintenance are crucial for safeguarding downstream communities and ecosystems. Monitoring and proactive risk management efforts are essential to ensure the continued safety and functionality of this important dam.

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 Van Rooy Lake Dam
Where does the data for Van Rooy 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.
