Summary

Built in 1960, this earth dam stands at a height of 19 feet and has a length of 415 feet, providing a storage capacity of 87 acre-feet. Situated on the TR-PILOT GROVE CREEK, this dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and is subject to state inspection and enforcement.

Despite its age, Tx No Name No 26 Dam has not been rated for its condition, but it poses a high risk (rated 2) due to its unknown hazard potential. This buttress-core dam lacks a spillway and is not equipped with outlet gates, presenting potential challenges in case of emergency situations. While the dam has not been modified in recent years, the lack of a detailed emergency action plan and updated contact information raises concerns about its readiness to handle unforeseen events.

Water resource and climate enthusiasts may find Tx No Name No 26 Dam an intriguing subject for further study, as its condition and management raise questions about the safety and sustainability of small, privately-owned dams in Texas. The dam's location, design, and regulatory oversight provide valuable insights into the complexities of managing and maintaining critical infrastructure in the face of changing climate conditions and increasing water resource challenges.

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.
