Summary
The dam has a height of 20 feet and a length of 160 feet, creating a reservoir with a storage capacity of 56 acre-feet. Despite being categorized as having a low hazard potential, the dam has not been rated for its condition, with its last inspection date dating back to September 1988.
Situated on TR-Snake Creek and Lake Ditch, J-Lake Dam offers a surface area of 4 acres for water enthusiasts to enjoy various recreational activities. While the dam is not state-regulated or permitted, it falls under the jurisdiction of the Natural Resources Conservation Service and is managed by a private owner. With its picturesque location and tranquil surroundings, J-Lake Dam serves as a popular destination for locals and visitors seeking a peaceful retreat in the heart of nature.
As climate and water resource enthusiasts, the data on J-Lake Dam provides valuable insights into the management and maintenance of earth dams for recreational purposes. While the dam's condition assessment remains unknown, its low hazard potential and historic construction by the USDA NRCS underscore the importance of regular inspections and risk management measures to ensure the safety and longevity of this vital water infrastructure in Morgan County, Indiana.

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.
