Summary
Built in 1975, this dam stands at 42 feet high and spans 643 feet in length, with a storage capacity of 575 acre-feet. Despite its age, the dam is in good condition, with a low hazard potential and a "Not Rated" condition assessment.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Novatny Brothers No.1 is subject to state regulations, inspections, and enforcement to ensure its safety and integrity. The dam serves as a vital water resource for the surrounding area, with a normal storage capacity of 475 acre-feet and a maximum discharge of 3536 cubic feet per second. While there are no associated structures or locks, the dam plays a crucial role in flood control and water management along the creek.
With Dusty Johnson (R) as the Congressional representative overseeing the area, Novatny Brothers No.1 remains a key infrastructure element in the region's water resource and climate management efforts. As a crucial part of the St. Paul District of the US Army Corps of Engineers, this dam continues to support the community by providing essential water storage and flood protection capabilities. Its strategic location and design make it a significant asset for sustainable water resource management in Tripp County, South Dakota.

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.
