Proffits Dam At Loomis Lake dam
Proffits Dam At Loomis Lake
Proffits Dam At Loomis Lake, located in Porter, Indiana, serves as a crucial water supply source for the surrounding area. Constructed in 1940, this earth dam stands at a height of 17 feet and spans 200 feet in length. With a storage capacity of 485 acre-feet, the dam primarily supports water supply purposes and also offers recreational opportunities for the community.
Managed by a public utility, this dam is regulated by the Indiana Department of Natural Resources, ensuring that it meets state permitting, inspection, and enforcement requirements. Despite its age, Proffits Dam has been assessed as satisfactory in condition, with a high hazard potential due to its location on an unnamed tributary of Flint Lake. The dam's spillway, an uncontrolled type, has a width of 200 feet, providing an essential safety feature in case of excess water flow.
While the risk assessment indicates moderate risk, the dam has not had an Emergency Action Plan (EAP) prepared or updated recently. With a focus on maintaining water supply and ensuring the safety of the surrounding community, ongoing monitoring and management measures are essential for the continued operation and resilience of Proffits Dam At Loomis Lake.

About Proffits Dam At Loomis Lake
Where does the data for Proffits Dam At Loomis Lake 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 below 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.

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.
