Randy Grgurich Dam dam
Randy Grgurich Dam
Randy Grgurich Dam, located in Lucas County, Iowa, is a privately owned structure primarily designed for grade stabilization along the TR - Little White Breast river or stream. Completed in 2014 by the USDA NRCS, this earth dam stands at a height of 28 feet and spans 330 feet in length. With a storage capacity of 17 acre-feet, it serves multiple purposes including grade stabilization, recreation, and water supply for the local community.
Despite its low hazard potential, the dam is regulated and inspected by the Iowa DNR, ensuring its safety and compliance with state standards. The spillway, which is uncontrolled, has a width of 18 feet, and the outlet gates are also uncontrolled. The risk assessment for the dam is moderate, with a DSAC assigned date yet to be determined. Although the condition assessment is currently not rated, the dam is equipped with emergency action plans in case of any unforeseen events, with emergency contacts and inundation maps yet to be prepared.
Overall, Randy Grgurich Dam is a crucial structure in the area, providing essential services while also being mindful of the potential risks associated with its operation. Its completion in 2014 marked a milestone in water resource management and climate resilience efforts in Lucas County, Iowa. With continued monitoring and maintenance, the dam remains a vital asset for the community, balancing the need for water supply, recreation, and environmental protection.
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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Randy Grgurich Dam
Where does the data for Randy Grgurich 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.
