Twin-Rush Creek Dam No. 2 dam
Twin-Rush Creek Dam No. 2
Twin-Rush Creek Dam No. 2, also known as John Hays Lake Dam, is a significant water resource structure located in Rush Creek Valley, Indiana. Built in 1969 by the USDA NRCS, this earth dam stands at a height of 65 feet and serves the primary purpose of water supply. With a normal storage capacity of 3,050 acre-feet and a maximum discharge of 8,500 cubic feet per second, the dam plays a crucial role in managing water resources in the region.
The dam is regulated by the Indiana Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality. Despite being classified as having a high hazard potential, the dam is currently assessed to be in fair condition. With a drainage area of 9 square miles and a surface area of 210 acres, Twin-Rush Creek Dam No. 2 provides both recreational opportunities and essential water supply services to the local community.
In the event of an emergency, the dam has an uncontrolled spillway with a width of 30 feet. While it has not undergone recent modifications or updates, the dam continues to meet the moderate risk assessment criteria. As a vital piece of infrastructure in the region, Twin-Rush Creek Dam No. 2 highlights the importance of proper management and maintenance of water resources in the face of changing climate conditions.
Dam data reference
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 Twin-Rush Creek Dam No. 2
Where does the data for Twin-Rush Creek Dam No. 2 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.
