Summary
With a dam height of 24 feet and a storage capacity of 421 acre-feet, Texley East serves as a vital resource for the local ecosystem, providing habitat for various aquatic species. The dam's low hazard potential and moderate risk assessment make it a key component in water resource management in the area.
Managed by the Forest Service, Texley East is equipped with an uncontrolled spillway and outlet gates. The dam has a surface area of 37 acres and drains an 8-square mile watershed, with a maximum discharge capacity of 484 cubic feet per second. Despite its age, Texley East has not been rated for its condition, but it undergoes inspections every 10 years to ensure its structural integrity and functionality.
As a significant feature on FIRST CREEK, Texley East plays a crucial role in water conservation, recreation, and wildlife preservation efforts in the region. With Dusty Johnson (R) as the Congressional representative, the dam contributes to the overall environmental sustainability and climate resilience of the area.

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.
