Lake Emmett Dam dam
Lake Emmett Dam
Lake Emmett Dam, located in Evansville, Illinois, stands as a testament to the importance of water resource management and climate resilience. Built in 1949, this private earth dam serves primarily for recreation, providing a serene oasis for water enthusiasts in Monroe County. With a height of 23 feet and a storage capacity of 154 acre-feet, Lake Emmett Dam plays a vital role in regulating the flow of the tributary Horse Creek.
Despite being classified as having a low hazard potential, Lake Emmett Dam is subject to regular state regulation, inspection, and enforcement by the Illinois Department of Natural Resources. The dam features an uncontrolled spillway and outlet gates, highlighting the need for ongoing monitoring and maintenance to ensure its structural integrity. With its moderate risk assessment rating, Lake Emmett Dam serves as a focal point for climate enthusiasts interested in the intersection of water resources, infrastructure, and risk management.
As a recreational hub in the St. Louis District, Lake Emmett Dam offers a picturesque setting for outdoor activities while also raising awareness about the importance of sustainable water use and dam safety. While its condition assessment may not be readily available, the dam's historical significance and environmental impact underscore the need for continued vigilance in managing our water resources in the face of a changing climate.
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 Lake Emmett Dam
Where does the data for Lake Emmett 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 Low 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.
