Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
