Unimin Tailings Pond O Dam Dam
Unimin Tailings Pond O Dam
Unimin Tailings Pond O Dam, also known as Pond 137, is a private-owned structure located in North Utica, Illinois. Built in 2010 by TRIAD ENGINEERING, INC., this earth-type dam stands at a height of 56 feet and has a length of 924 feet. With a storage capacity of 650 acre-feet, the dam primarily serves the purpose of containing tailings from mining operations.
Despite being categorized as having a low hazard potential, the dam is subject to state regulation and inspection by the Illinois Department of Natural Resources. The spillway type is uncontrolled, with a width of 2 feet. The dam's drainage area is 0.07 square miles, with a surface area of 33.8 acres. While the risk assessment indicates a moderate level of risk, specific risk management measures and emergency action plans are not readily available.
Overall, Unimin Tailings Pond O Dam plays a crucial role in managing mining byproducts and ensuring environmental safety in the area. Its structural integrity and regulatory oversight are essential for maintaining the dam's functionality and preventing any potential hazards to the surrounding community and ecosystem. Climate and water resource enthusiasts would find this dam's design and management details intriguing in the context of sustainable resource utilization and environmental protection.

About Unimin Tailings Pond O Dam
Where does the data for Unimin Tailings Pond O 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 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.
