Summary

Completed in 1948, this earth dam stands at a height of 10.46 feet and spans a length of 126 feet along the Oyster Creek. With a storage capacity of 3,234 acre-feet, it serves as a key component in the water supply system for the surrounding area.

Managed by a local government entity and regulated by the Texas Commission on Environmental Quality (TCEQ), Dam No 1 has a moderate risk assessment rating. While its hazard potential and condition assessment are not available, regular inspections are conducted every five years to ensure its structural integrity. The dam's spillway type is uncontrolled, with a width of 50 feet, and it has one uncontrolled outlet gate.

For water resource and climate enthusiasts, Dam No 1 is a fascinating structure to study due to its historical significance, engineering design, and impact on the local ecosystem. As part of the larger water management system in the region, this dam plays a vital role in providing irrigation water and maintaining water supply for various purposes. Its location along the Oyster Creek and its association with the Fort Worth District of the US Army Corps of Engineers make it a unique and important piece of infrastructure worth exploring further.

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.
