Summary

The dam, primarily made of earth with a buttress core, was designed by Ronald Bivens and is not regulated by the state. It has a low hazard potential and is currently not rated for its condition.

Managed by the Natural Resources Conservation Service, the dam has a storage capacity of 39 acre-feet and serves the primary purpose of water resource management. Despite its uncontrolled spillway and outlet gates, the dam poses a moderate risk due to its location and design. The surrounding area, with a surface area of 26 acres and no designated drainage area, may be at risk in the event of a breach or failure.

While Robinson Lake Dam may not be subject to regular inspections or state regulations, its moderate risk level highlights the importance of ongoing monitoring and maintenance. As water resource and climate enthusiasts, it is crucial to recognize the potential hazards associated with dams like Robinson Lake and advocate for proactive measures to ensure their safety and integrity for the surrounding community and ecosystem.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
