Summary

Built in 1986 by USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 26 feet and a length of 610 feet, it has a storage capacity of 122 acre-feet, providing essential water resources for the surrounding area.

Despite not being state-regulated, Ken Gill Gss No 1 is equipped with state-permitting and inspection processes to ensure its structural integrity and safety. The dam is characterized by its buttress core type and is considered to have a high hazard potential. Although its condition assessment is currently not rated, efforts are being made to assess and manage potential risks associated with the structure.

With Mac Thornberry (R) representing the district, Ken Gill Gss No 1 stands as a significant asset in the region's water resource management. Its historical significance, combined with its multifunctional design and risk management strategies, make it a noteworthy site for water resource and climate enthusiasts seeking to understand the intersection of infrastructure and environmental stewardship.

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.
