Carrigan Pond Dam dam
Carrigan Pond Dam
Carrigan Pond Dam, located in Morgan County, Illinois, is a private earth dam designed by the USDA NRCS and completed in 1972 for the primary purpose of creating a Fish and Wildlife Pond. With a dam height of 29 feet and a length of 253 feet, the reservoir has a storage capacity of 49 acre-feet and serves multiple purposes including recreation and wildlife habitat. The dam is regulated by the Illinois Department of Natural Resources and is considered to have a low hazard potential.
Despite its low hazard potential, Carrigan Pond Dam poses a moderate risk, as indicated by a risk assessment rating of 3. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 190 cubic feet per second. The dam is inspected regularly, with the most recent inspection conducted in April 2021. While the condition assessment is not available, the dam is considered to be in a satisfactory state based on available data.
Located on TR- BRUSHY FORK river, Carrigan Pond Dam stands as a testament to the importance of water resource management for both wildlife conservation and recreational activities. With its tranquil surroundings and diverse ecosystem, the dam serves as a vital resource for the local community while also highlighting the need for ongoing monitoring and maintenance to ensure the safety and integrity of the structure.

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 Carrigan Pond Dam
Where does the data for Carrigan 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 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.
