Summary
Tischler is a privately owned dam located in Perkins, South Dakota, along the TR MOREAU river. Built in 1948, this earth dam stands at a height of 13 feet with a length of 670 feet, providing a maximum storage capacity of 97 acre-feet. With state regulation and enforcement in place, the dam is maintained to meet inspection standards, although its condition is currently listed as "Not Rated" with a low hazard potential.
Operated by the St. Paul District of the US Army Corps of Engineers, J. Tischler serves primarily for water resource management purposes in the region. The dam's design and construction are overseen by the South Dakota Department of Environment and Natural Resources (DENR), ensuring compliance with state permitting and inspection requirements. Despite its age, the dam continues to play a vital role in flood control and water supply management for the local community.
As an essential infrastructure for the area, J. Tischler remains a key component in the overall water resource system, with a capacity to handle a maximum discharge of 1400 cubic feet per second. While its condition assessment is pending, the dam's low hazard potential indicates a relatively low risk of failure. With ongoing monitoring and maintenance, this structure continues to safeguard the surrounding area from potential water-related emergencies.

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.
