Summary

With a height of 7 feet and a length of 12,565 feet, this levee has a storage capacity of 1,024 acre-feet, with a normal storage of 836 acre-feet over a surface area of 136 acres. It is regulated by the Texas Commission on Environmental Quality (TCEQ) and is inspected regularly to ensure its structural integrity and functionality.

Despite its age, E W Monteith No 1 Levee has a moderate risk assessment rating of 3, indicating a certain level of risk but not deemed hazardous. The dam has an uncontrolled spillway and one uncontrolled outlet gate, with no locks or discharge capacity listed. While the condition assessment is not rated, the levee has not been modified in recent years, and the last inspection date was in 1976. Even though the hazard potential is not available, the levee is still actively monitored and inspected by the state regulatory agency.

For water resource and climate enthusiasts, E W Monteith No 1 Levee serves as an essential infrastructure for irrigation and water supply in the region. Its historical significance and continued operation demonstrate the importance of maintaining and regulating such structures to ensure the safety and sustainability of water resources in the area. With its moderate risk assessment and regular inspections, the levee continues to play a crucial role in managing water flow and storage along the river or stream, contributing to the overall water management efforts in Chambers, Texas.

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.
