Summary

This privately-owned Earth dam, with a height of 18 feet and a length of 7571 feet, provides a storage capacity of 4776 acre-feet and covers a surface area of 349.6 acres. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections and enforcement to ensure its structural integrity.

The levee, designed by Collis Consulting Co, stands along the South Sulphur River, within the jurisdiction of the state of Texas. With a high hazard potential rating and a risk assessment of 2 (on a scale of 1 to 5), the dam is considered to be at risk for potential issues. Despite its risk level, the Sulphur Bluff Realty Phase I Levee has not been rated for its condition and lacks an Emergency Action Plan (EAP) or inundation maps. The dam's outlet gates consist of one non-listed type, and it does not have a spillway.

While the Sulphur Bluff Realty Phase I Levee plays a crucial role in providing irrigation water to the surrounding areas, its high risk level underscores the importance of ongoing monitoring and maintenance to prevent any potential hazards or failures. Climate and water resource enthusiasts will find this dam's data and risk assessment a compelling topic for further study and discussion on the intersection of infrastructure, climate change, and water management.

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.
