J&T Cattle Company No. 1 Dam
J&T Cattle Company No. 1
J&T Cattle Company No. 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.

About J&T Cattle Company No. 1
Where does the data for J&T Cattle Company No. 1 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.

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.
- 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.
- 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.
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, environmental 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.
