Summary
This private-owned structure stands at a height of 47 feet and has a storage capacity of 376 acre-feet. The dam, constructed with earth and buttress core types, serves as a vital component for water resource management in the area, despite lacking a spillway and having limited associated structures.
Despite being categorized as having a high risk potential, the condition of Spencer Lake Dam remains unrated. However, regular inspections are conducted in compliance with state regulations, with permitting and inspections managed by the Texas state agency. The dam's primary function and its role in controlling water flow and storage in the region make it a significant asset for climate enthusiasts and water resource managers interested in the hydrological dynamics of the area.
As one of the key structures along the Little Gyp Creek, Spencer Lake Dam serves as a critical point for understanding water resource management in Donley, Texas. Its historical significance, design features, and operational aspects make it a focal point for researchers and enthusiasts looking to study the intersection of water resource management and climate adaptation in the region. With its unique characteristics and risk profile, Spencer Lake Dam offers a compelling case study for those interested in the sustainable management of water resources in a changing climate.

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.
