Gross Farms Dam dam
Gross Farms Dam
Located in Morgan County, Illinois, Gross Farms Dam is a privately-owned structure designed by Hutchison Engineering, Inc. The dam, completed in 2005, serves primarily for recreational purposes and is regulated by the Illinois Department of Natural Resources. With a height of 27 feet and a length of 395 feet, the dam has a storage capacity of 335 acre-feet and a drainage area of 1.37 square miles, with a maximum discharge of 1710 cubic feet per second.
The dam, situated on TRIB SANDY CREEK, features an uncontrolled spillway with a width of 12 feet and is classified with a low hazard potential. The structure's condition assessment is currently not available, but regular inspections are carried out every 5 years. Although the risk assessment is rated as moderate, the dam has not been assigned a Dam Safety Action Classification (DSAC) date, indicating a need for ongoing monitoring and risk management measures. Despite its low hazard potential, Gross Farms Dam plays a crucial role in water resource management and public safety in the region.
Overall, Gross Farms Dam stands as a vital infrastructure in Morgan County, Illinois, providing recreational opportunities while also serving as a key component in the area's water resource management. With its moderate risk assessment and ongoing inspections, the dam exemplifies the importance of maintaining and monitoring such structures to ensure their continued safety and functionality. As a significant feature on TRIB SANDY CREEK, Gross Farms Dam represents a critical piece of the region's water infrastructure, requiring careful oversight and management to protect both the environment and the community it serves.

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 Gross Farms Dam
Where does the data for Gross Farms 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.
