Summary
17, also known as Wimmer Lake, is a local government-owned structure located in Parke, Indiana. Completed in 1974 by the USDA NRCS, this earth dam stands at a height of 36 feet and stretches 555 feet in length, serving its primary purpose of flood risk reduction along an unnamed tributary of Little Raccoon Creek. With a normal storage capacity of 67 acre-feet and a maximum storage of 426 acre-feet, this dam plays a crucial role in managing water resources in the area.
The dam, with a fair condition assessment as of 2009, has a low hazard potential and is regularly inspected by the state regulatory agency, IDNR, to ensure its safety and effectiveness. Despite being without a spillway, the structure has a maximum discharge capacity of 1966 cubic feet per second, showcasing its ability to handle significant water flow during flood events. Its location in the Louisville District adds to its significance, providing valuable insights for water resource and climate enthusiasts interested in understanding the management of water infrastructure in the region.
Overall, Little Raccoon Dam No. 17 stands as a testament to the collaborative efforts of local governments and agencies in safeguarding communities from flood risks. Its presence underscores the importance of proactive measures in water resource management and highlights the critical role that dams play in maintaining water security and resilience in the face of changing climate conditions. For those passionate about water resources and climate resilience, this dam serves as a tangible example of sustainable infrastructure that contributes to the well-being of communities and ecosystems alike.

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.
