Murrayville Woodson Lake Dam dam
Murrayville Woodson Lake Dam
Murrayville Woodson Lake Dam, located in Illinois, serves as a vital water supply resource for the region. Built in 1963 by CALDWELL-RHODES ENGINEERS, this earth dam stands at a height of 28 feet and spans a length of 248 feet. With a storage capacity of 180 acre-feet and a normal storage level of 99 acre-feet, the dam plays a crucial role in managing water resources for the area.
Managed by a Public Utility, the dam is regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections to ensure its safety and functionality. The dam's spillway type is uncontrolled, with a width of 22 feet, and it has a significant hazard potential. Despite lacking condition assessment data, the dam's risk assessment is moderate, highlighting the importance of ongoing monitoring and maintenance to mitigate potential risks.
Situated on the TRIB HENRY CREEK and surrounded by a drainage area of 0.3 square miles, Murrayville Woodson Lake Dam is a key infrastructure piece in Winchester, Illinois. With a designated purpose of water supply, this dam not only supports the local community but also contributes to the overall water management efforts in the region. As water resource and climate enthusiasts, it is important to recognize the significance of structures like this dam in ensuring sustainable water access and security for all.
Dam data reference
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 Murrayville Woodson Lake Dam
Where does the data for Murrayville Woodson 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 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.
