Summary

Completed in 1950, this structure stands at a hydraulic height of 19 feet and a structural height of 22.5 feet, with a total length of 254 feet. The dam has a storage capacity of 136 acre-feet and serves the primary purpose of flood control along the river.

With a significant hazard potential and a moderate risk assessment rating, Robinson is a crucial piece of infrastructure in the region. Despite not being state regulated or inspected, the dam plays a vital role in managing water flow and protecting downstream areas from potential flooding. It is important for water resource and climate enthusiasts to monitor the condition and maintenance of Robinson to ensure its continued effectiveness in mitigating flood risks.

While the dam's current condition is not rated, regular inspections every five years help assess its structural integrity and functionality. Emergency action plans and risk management measures should be in place to address any potential issues that may arise. As a key component in the region's flood control system, Robinson serves as a reminder of the importance of maintaining and monitoring water infrastructure to safeguard communities and the environment.

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.
