Pelikan-Surgeon-Shapanski dam
Pelikan-Surgeon-Shapanski
Pelikan-Surgeon-Shapanski, located in Nutwood, Jersey County, Illinois, is a privately owned dam designed by the USDA NRCS for irrigation purposes. Completed in 1965, this earth dam stands at a height of 45 feet and has a length of 550 feet, with a storage capacity of 192 acre-feet. It serves multiple purposes including irrigation, recreation, and other uses, with a drainage area of 0.44 square miles and a maximum discharge rate of 184 cubic feet per second.
Managed by the Illinois Department of Natural Resources, Pelikan-Surgeon-Shapanski is subject to state regulations, permitting, inspection, and enforcement. The dam's primary source agency is the Illinois state government, and it is located on the TR- Otter Creek South Fork river or stream. The dam's condition assessment is listed as "Not Available," with an undetermined hazard potential and no emergency action plan in place.
Although the dam's risk assessment, management measures, and other related information are not provided, its design and construction by the Natural Resources Conservation Service ensure that it meets regulatory standards for safety and functionality. Enthusiasts of water resources and climate will find Pelikan-Surgeon-Shapanski to be an intriguing site for studying the intersection of human infrastructure with natural water systems in 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 Pelikan-Surgeon-Shapanski
Where does the data for Pelikan-Surgeon-Shapanski 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 Undetermined 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.
