Summary
Standing at a height of 7 feet with a length of 8800 feet, this Earth type dam has a storage capacity of 646 acre-feet and covers a surface area of 92 acres. Despite having no spillway, the dam has proven to be a reliable water resource for the region.
Managed privately and regulated by the Texas Commission on Environmental Quality (TCEQ), Middleton Reservoir No 2 Dam has undergone periodic inspections with its hazard potential labeled as "Not Available" and its condition assessment marked as "Not Rated." However, a risk assessment has classified the dam as having a high risk level of 2, emphasizing the importance of proper risk management measures. With no flood maps or emergency action plans prepared, there is a potential need for further evaluation and preparedness in case of emergencies.
While the dam has not been modified since its completion, its primary purpose of irrigation highlights its significance in sustaining agricultural activities in the area. With a steady drainage area and no identifiable discharge, Middleton Reservoir No 2 Dam stands as a crucial water resource infrastructure in the region, requiring continuous monitoring and potential enhancements to ensure its long-term functionality and safety.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
