Central Alexander County Sewage Treatment Pond Dam Dam
Central Alexander County Sewage Treatment Pond Dam
Central Alexander County Sewage Treatment Pond Dam, located in Alexander, Illinois, was completed in 1998 and is owned privately. The dam, with a height of 7 feet and a length of 2644 feet, serves as a crucial structure for managing wastewater and has a maximum storage capacity of 64 acre-feet. Situated on TRIB PIGEON ROOST CREEK, the dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and functionality.
This Earth type dam with a stone core plays a vital role in controlling the flow of water and preventing potential hazards. Despite its low hazard potential, the dam is considered to have a very high risk (1) due to its location and surrounding conditions. The dam features a controlled spillway and outlet gates for efficient water management. Although the dam's condition assessment is not available, it is essential for water resource and climate enthusiasts to monitor and support the maintenance of this critical infrastructure to safeguard the local environment and community.
With a surface area of 10 acres and a drainage area of 0.02 square miles, this dam not only provides essential wastewater treatment but also contributes to the overall water management system in the region. The dam's association with Southern Engineering Corp underscores the importance of professional design and construction in ensuring its long-term effectiveness. As climate change continues to impact water resources, the Central Alexander County Sewage Treatment Pond Dam serves as a reminder of the critical role infrastructure plays in mitigating environmental risks and protecting water quality for future generations.

About Central Alexander County Sewage Treatment Pond Dam
Where does the data for Central Alexander County Sewage Treatment Pond 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.
