Lake Mildred Dam dam
Lake Mildred Dam
Lake Mildred Dam, located in Monroe, Illinois, serves as a recreational haven for water resource and climate enthusiasts. Built in 1950, this private earth dam stands at 19 feet high and stretches 440 feet in length, providing a storage capacity of 205 acre-feet. The dam overlooks the picturesque TRIB ONEMILE RACE CREEK, offering a serene escape for visitors seeking outdoor adventure.
Managed by the Illinois Department of Natural Resources, Lake Mildred Dam boasts a controlled spillway with a width of 27 feet, ensuring the safety of the surrounding area. Despite its low hazard potential, the dam's risk assessment indicates a very high risk level, highlighting the importance of regular inspections and maintenance. The dam's emergency action plan status and condition assessment are currently not available, underscoring the need for continued vigilance and risk management measures to safeguard this vital water resource.
For those seeking a tranquil retreat in Steggenevie, Lake Mildred Dam stands as a testament to the harmonious coexistence of man-made structures and natural beauty. Whether enjoying recreational activities on the lake or simply basking in the peaceful surroundings, this dam is a testament to the enduring allure of water resources in shaping our climate-conscious world.

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 Mildred Dam
Where does the data for Lake Mildred 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.
