Summary

1, also known as Lower Reservoir, is a privately owned water storage facility located in Stanislaus County, California. This Earth type dam was completed in 2013 and serves the primary purpose of water supply for irrigation and other agricultural needs in the area. With a dam height of 22 feet and a storage capacity of 131.8 acre-feet, this reservoir plays a crucial role in managing water resources in the region.

Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, J&T Cattle Company No. 1 is subject to state regulations, inspections, and enforcement to ensure its safety and compliance with guidelines. The dam has a low hazard potential and is currently assessed to be in fair condition as of September 2017. Regular inspections are conducted, with the last inspection taking place in January 2020, to monitor the structural integrity and overall performance of the reservoir.

Situated along Peaslee Creek and under the jurisdiction of the San Francisco District of the US Army Corps of Engineers, J&T Cattle Company No. 1 contributes to the local water supply and supports agricultural activities in the area. With its modest surface area of 15.7 acres and a hydraulic height of 17.94 feet, this reservoir showcases the importance of efficient water management practices in sustaining the region's water resources and adapting to changing climate conditions.

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.
