Summary
Built in 1893 with an earth core and concrete structure, the dam stands at a height of 12 feet and stretches 150 feet in length. Its primary purpose is for hydroelectric power generation, with a normal storage capacity of 1,775 acre-feet over a surface area of 130 acres.
Managed by the Federal Energy Regulatory Commission, Redmon (Marshall) Perrin 1 has a high hazard potential due to its proximity to populated areas. Despite its age, the dam undergoes regular inspections to ensure its structural integrity and operational safety. The dam's spillway, an uncontrolled type with a width of 150 feet, helps regulate water flow and prevent overflow during peak discharge events.
With a drainage area of 352 square miles and a maximum discharge capacity of 4,200 cubic feet per second, Redmon (Marshall) Perrin 1 plays a crucial role in water resource management and flood control in the region. Its historical significance and ongoing maintenance efforts highlight the importance of sustainable infrastructure practices for climate resilience and water conservation.

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.
