Woodlake Estates Dam dam
Woodlake Estates Dam
Woodlake Estates Dam, located in Springfield, Illinois, is a privately owned structure designed by Hoelscher Engineering for flood risk reduction along the Trib Spring Creek. With a dam height of 25.5 feet and a storage capacity of 138 acre-feet, the dam serves as a critical infrastructure to manage water flow and reduce the risk of flooding in the area. The dam also provides recreational opportunities for the community, enhancing its value beyond flood control.
The dam's spillway type is uncontrolled, with a width of 56 feet, allowing for the safe release of excess water during heavy rainfall events. Despite its high hazard potential, the dam is regularly inspected and maintained by the Illinois Department of Natural Resources to ensure the safety of nearby residents and properties. While the condition assessment is currently not available, the dam's risk assessment is moderate, indicating the need for ongoing risk management measures to mitigate potential issues.
In conclusion, Woodlake Estates Dam plays a crucial role in protecting the surrounding area from flooding while offering recreational benefits to the community. With its strategic design and regulatory oversight, the dam serves as a vital piece of infrastructure in managing water resources and climate challenges in Sangamon County, 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.

About Woodlake Estates Dam
Where does the data for Woodlake Estates 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 High 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.
