Summary
Built in 1962 by the USDA NRCS, this earth dam stands at 25 feet high and has a storage capacity of 57 acre-feet. The dam serves the primary purpose of irrigation and is regulated by the state agency DNRC.
Situated on TR-Fords Creek, Ruseteun #2 has a low hazard potential and has not been rated for its condition assessment. Despite being inspected by the state agency, the dam does not have a designated inspection frequency or last inspection date on record. The spillway width is 25 feet, and the maximum discharge capacity is 1000 cubic feet per second, ensuring effective water management in the area.
While the dam's emergency action plan status is not specified, it is reassuring to note that Ruseteun #2 meets state regulatory requirements and plays a crucial role in supporting agricultural activities in the region. With its strategic location and significant storage capacity, this dam is a key infrastructure asset for water resource management and climate resilience in the area.

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.
