About this dam

Msdgc Upper Acid Lake Dam

Msdgc Upper Acid Lake Dam, also known as Lower Ue Lake, is a local government-owned structure located in Fulton County, Illinois. Built in 1958 by GALE & UNITED ELECTRIC COAL CO., this earth dam stands at a height of 35 feet and spans a length of 140 feet. With a primary purpose of recreation, the dam offers a storage capacity of 570 acre-feet, providing ample opportunities for outdoor activities and water sports in the area.

Managed by the Illinois Department of Natural Resources, Msdgc Upper Acid Lake Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safe operation. Despite being classified as having a low hazard potential, a moderate risk assessment indicates the need for ongoing risk management measures. While the condition assessment is not currently available, the dam has a regular inspection frequency of 5 years, with the last inspection conducted in November 2017.

Situated on TRIB BIG CREEK-OFFSTREAM, Msdgc Upper Acid Lake Dam plays a crucial role in water resource management and climate resilience in the region. With its uncontrolled spillway and outlet gates, the dam serves as a vital infrastructure for flood control and recreational purposes. As water resource and climate enthusiasts, understanding the significance of such structures is essential for sustainable development and environmental conservation efforts in Illinois.

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.

FAQ

About Msdgc Upper Acid Lake Dam

Where does the data for Msdgc Upper Acid 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 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.
