Summary

The dam is classified as an Earth type structure with a height of 14 feet and a length of 2415 feet, providing a maximum storage capacity of 274 acre-feet. Despite being privately owned, the dam is regulated by the state and undergoes regular inspections to ensure its safety and functionality.

Situated on TR-LOS OLMOS CREEK, the dam plays a vital role in water resource management and contributes to the overall water supply infrastructure in the area. With a surface area of 30 acres and a normal storage capacity of 120 acre-feet, the dam helps to mitigate water scarcity issues and supports various agricultural and domestic water needs. Although the dam lacks a spillway, it is equipped with one outlet gate to control water flow and ensure operational efficiency.

While the dam is considered to have a high risk potential, its condition is currently not rated, highlighting the need for continued monitoring and maintenance. As a key component of the water supply system in La Salle County, Monte Cartado Ranch Tank No 1 Dam serves as a critical resource for local communities and underscores the importance of sustainable water management practices in the face of climate variability and increasing water demand.

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.
