White Hall Reservoir Dam dam
White Hall Reservoir Dam
White Hall Reservoir Dam, located in Greene County, Illinois, was completed in 1952 and serves primarily for recreation and water supply purposes. With a dam height of 38 feet and a length of 1060 feet, the dam impounds the White Hall Reservoir on the TRIB WOLF RUN CREEK. The dam has a storage capacity of 817 acre-feet and a surface area of 50 acres, making it a significant water resource in the area.
Managed by the USDA NRCS, the White Hall Reservoir Dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its structural integrity. The dam is classified as having a "Significant" hazard potential, with a moderate risk assessment rating. While the condition assessment is currently not available, the dam's emergency action plan status is also unknown. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 673 cubic feet per second.
For water resource and climate enthusiasts, the White Hall Reservoir Dam presents an intriguing case study of dam infrastructure in Illinois. As a vital component of the local water supply and recreation activities, the dam's management and maintenance are crucial to ensure the safety of nearby communities and the preservation of the surrounding environment. With its historical significance and ongoing regulatory oversight, the White Hall Reservoir Dam serves as a focal point for understanding the intersection of water resource management, infrastructure development, and climate resilience in the region.

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 White Hall Reservoir Dam
Where does the data for White Hall Reservoir 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 Significant 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.
