Summary

With a height of 8 feet and a length of 2220 feet, this levee-complex serves a primary purpose of "Other" and has a normal storage capacity of 42 acre-feet. Although the spillway type is listed as "None," it is equipped with one outlet gate.

Situated along the OFF CH-TR-AUSTIN BAYOU, Reservoir No 10 Levee-Complex No 2 falls under the jurisdiction of the state of Texas and is subject to state permitting, inspection, and enforcement. The risk assessment for this structure is rated as High (2), indicating a potential for significant hazard. However, the condition of the dam is currently not rated, and there is no Emergency Action Plan (EAP) in place.

Despite its age and potential risk, Reservoir No 10 Levee-Complex No 2 remains a vital component of the water resource infrastructure in the area. Its strategic location and design make it a critical asset for water management in Brazoria, Texas. Enthusiasts of water resources and climate monitoring would find this structure an intriguing subject for further study and analysis.

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.
