Jeffries Lake Dam dam
Jeffries Lake Dam
Jeffries Lake Dam in Parke, Indiana, is a privately-owned structure built in 1972 by the USDA NRCS for recreational purposes. Sitting on an unnamed tributary of Molasses Creek, this earth dam stands at 22.45 feet high and has a storage capacity of 65 acre-feet. With a surface area of 2.29 acres and a drainage area of 0.04 square miles, the dam has a spillway width of 25 feet and a maximum discharge capacity of 181 cubic feet per second.
Despite being classified as having a high hazard potential, Jeffries Lake Dam is currently in fair condition as assessed in 2009. The dam has been inspected regularly every 2 years, with the last assessment conducted in March 2009. While there are no outlet gates, the dam has an uncontrolled spillway type and is regulated by the Indiana Department of Natural Resources. The risk assessment for the dam is moderate, and there are no known emergency action plans or inundation maps prepared for the structure.
Located in Minshall, Indiana, Jeffries Lake Dam serves as a vital recreational spot in the area, offering opportunities for outdoor enthusiasts to enjoy the surrounding natural beauty. With its rich history and importance in water resource management, the dam stands as a testament to the efforts of the USDA NRCS in providing sustainable solutions for water conservation and recreation in the region.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Jeffries Lake Dam
Where does the data for Jeffries 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.
