Summary
This irrigation structure, completed in 1951, serves the primary purpose of providing water for agricultural purposes in the region. With a dam height of 18 feet and a storage capacity of 548 acre-feet, Catron Irrigation plays a crucial role in supporting the local farming community by ensuring a reliable water supply for irrigation.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Catron Irrigation is regulated and inspected to ensure its safe operation and compliance with state regulations. While the dam has a low hazard potential, its condition is currently rated as "Not Rated," indicating a need for further assessment. Despite this, the structure has not undergone any modifications in recent years and remains a vital component of the local water resource management infrastructure.
Located on the Little Missouri River tributary, Catron Irrigation is essential for sustaining agriculture in the region. With a maximum discharge capacity of 1050 cubic feet per second, the structure plays a crucial role in managing water resources during periods of high demand. As climate change continues to impact water availability, structures like Catron Irrigation will become increasingly important in ensuring the resilience of agricultural operations in the face of changing environmental conditions.

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.
