Lehew Dam No 1 Reservoir Report

Last Updated: December 5, 2025

Lehew Dam No 1, located in Dickens, Texas, is a privately owned earth dam completed in 1958 with a primary purpose identified as "Other." The dam, standing at a height of 34 feet and a length of 400 feet, has a storage capacity of 96 acre-feet and serves as a critical structure for water resource management in the region.

Summary

The dam is situated on J-2 Canyon Creek and falls under the jurisdiction of the Tulsa District of the US Army Corps of Engineers.

Despite being rated as "Not Available" in terms of hazard potential and "Not Rated" in condition assessment, Lehew Dam No 1 poses a high risk (2) according to risk assessment data. The dam lacks a spillway and has no associated locks, with only one outlet gate identified. The last recorded inspection of the dam dates back to February 1964, raising concerns about the need for updated assessments and emergency preparedness plans. As an essential infrastructure for water storage and conservation in the area, Lehew Dam No 1 warrants ongoing attention and monitoring by relevant regulatory agencies to ensure its safety and functionality in the face of changing climate conditions.

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.
