Summary
Built in 1990 for irrigation purposes, this earth dam reaches a height of 76 feet, with a hydraulic height of 68 feet and a structural height of 80 feet. The dam boasts a storage capacity of 1900 acre-feet, serving the vital role of providing water for agricultural needs in the region.
With a spillway width of 20 feet and a maximum discharge rate of 90 cubic feet per second, the T-S Ranch Dam has undergone multiple modifications over the years to enhance its operational efficiency. The dam's hazard potential is deemed significant, reflecting the importance of regular inspections and maintenance to ensure its structural integrity. Despite its condition assessment being labeled as "Not Rated," the dam remains a key component in water management efforts in the area, with a moderate risk level assigned.
As a pivotal structure in the local water infrastructure, the T-S Ranch Dam plays a crucial role in sustaining the agricultural activities in the region. With its strategic location on Boulder Creek-TR, this dam serves as a lifeline for irrigation purposes, highlighting the intersection of water resource management and climate resilience in the face of evolving environmental challenges.

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.
