Summary

Standing at a height of 13 feet with a length of 9500 feet, the dam has a storage capacity of 510 acre-feet and serves as a vital water resource for the surrounding area. Despite being regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoing state inspections, the dam's condition assessment is currently not rated, posing a potential risk due to its high hazard potential.

The reservoir, situated off CH-Cedar Bayou, plays a crucial role in water management and irrigation in Liberty County, Texas. With a primary purpose of irrigation, the dam is designed with stone core types and foundations consisting of rock and soil. Though the dam lacks spillways and locks, it is equipped with one outlet gate. However, the lack of recent inspection data since 1982 raises concerns about the dam's current structural integrity and maintenance practices, highlighting the need for regular assessments and risk management measures to ensure the safety and sustainability of the reservoir.

In light of the limited information available on the dam's condition and emergency preparedness, stakeholders and officials must prioritize conducting regular inspections, updating emergency action plans, and implementing risk management measures to mitigate potential hazards. As a critical infrastructure for water resource management in the region, the Jm Frost Reservoir No 2 Levee requires proactive measures to safeguard against potential risks and ensure its long-term functionality in the face of changing climate conditions and increasing water demands.

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.
