Summary
This Federal-owned dam, with a height of 10 feet and a hydraulic height of 7 feet, serves to divert water for agricultural purposes and helps manage potential flooding in the region. It has a controlled spillway type with a width of 20 feet, ensuring efficient water flow control during heavy rainfall events.
The dam's primary purpose is irrigation, with a storage capacity of 100 acre-feet and a normal storage level of 70 acre-feet. It is constructed primarily of earth and stone materials, with a foundation in soil. Despite its low hazard potential, the dam's risk assessment is rated as very high, highlighting the importance of proper maintenance and monitoring. The last inspection took place in April 2013, with an inspection frequency of every five years, and the condition assessment is currently not rated.
With its strategic location on the Carson River and its essential role in water management and agricultural activities, Sagouspie Diversion Dam is a crucial infrastructure for the local community. As a Federal-owned structure, it represents a key component of the region's water resource management system, ensuring water supply for irrigation while mitigating flood risks. Proper maintenance and monitoring are essential to ensure the dam's continued effectiveness in serving its intended purposes and protecting the surrounding areas from potential water-related hazards.

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.
