Prairie Cr. No. B-2-1 (Cropp) dam
Prairie Cr. No. B-2-1 (Cropp)
Prairie Creek No. B-2-1, also known as Cropp Dam, is a significant earth dam located in Daviess, Indiana, designed by the USDA NRCS to serve as a flood risk reduction structure along the Dinken Creek. Completed in 1964, this dam stands at a height of 28 feet with a length of 700 feet, offering a storage capacity of 664 acre-feet and a maximum discharge rate of 2500 cubic feet per second. Despite its fair condition assessment in 2014, the dam's hazard potential is considered significant, warranting regular inspections and a high-risk assessment score of 2.
Owned by the local government and regulated by the Indiana Department of Natural Resources, this dam plays a crucial role in managing the water resources in the area, covering a drainage area of 1.98 square miles and offering flood protection to the surrounding community of Washington-Offstream. With a surface area of 105 acres and a normal storage capacity of 203 acre-feet, Prairie Creek No. B-2-1 serves as a key structure in the region's water management infrastructure, highlighting the importance of its continued maintenance and monitoring to ensure the safety of residents and property downstream.
As a part of the Louisville District and designated for flood risk reduction purposes, Cropp Dam remains a vital component of the water resource management strategy in Indiana. With a history of inspections and a fair condition assessment, this dam demonstrates the ongoing efforts to uphold safety standards and mitigate potential risks associated with its operation. As water resource and climate enthusiasts, understanding the significance of structures like Prairie Creek No. B-2-1 underscores the importance of sustainable infrastructure planning and management to address the challenges posed by changing environmental conditions and increasing water-related hazards in the region.
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.

About Prairie Cr. No. B-2-1 (Cropp)
Where does the data for Prairie Cr. No. B-2-1 (Cropp) 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 Significant 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.
