Libbys Lagoon 4 Dam dam
Libbys Lagoon 4 Dam
Libbys Lagoon 4 Dam, located in Morton, Illinois, was completed in 1974 and is owned by a private entity. Designed by Libby, McNeil & Libby Co., this earth dam stands at a height of 28 feet with a length of 1930 feet, providing a storage capacity of 94 acre-feet. The dam is situated on the TRIB BULL RUN CREEK-OFFSTREAM, under the regulatory oversight of the Illinois Department of Natural Resources.
Despite its low hazard potential, the dam poses a high risk due to its condition assessment being unavailable, indicating a potential need for further evaluation and maintenance. With a regular inspection frequency of 5 years, the dam's emergency action plan status and risk management measures are currently not available. While the dam has no spillway and is not associated with any federal agencies, its location and purpose suggest a vital role in local water resource management within the Tazewell County area.
Water resource and climate enthusiasts interested in the Libbys Lagoon 4 Dam would find it intriguing due to its historical significance, design characteristics, and the need for potential risk mitigation measures in the face of changing climate conditions. The dam's presence highlights the importance of private ownership in maintaining critical infrastructure for water storage and flood control, highlighting the intersection of environmental stewardship and private investment in water resource management. Further assessment and monitoring of this dam's condition and emergency preparedness may be necessary to ensure its long-term sustainability and resilience in the face of future challenges.

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 Libbys Lagoon 4 Dam
Where does the data for Libbys Lagoon 4 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.
