Summary
The dam, designed by USDA NRCS, serves as a crucial water supply source with a storage capacity of 150 acre-feet and a normal storage level of 80 acre-feet. The primary purpose of this earth dam, with a buttress core type, is to provide water for various uses in the region.
Despite its importance for water supply, Palmer Tank Dam has not been rated for its condition and its hazard potential is labeled as "Not Available." The risk assessment has classified it as high risk (2), indicating the need for attention and potential management measures to ensure its safety and functionality. With no spillway and limited information on inspections and emergency preparedness, the dam poses challenges that require further evaluation and potentially enhanced risk management strategies.
As part of the Fort Worth District, the dam is not under USACE ownership, further complicating regulatory oversight and maintenance responsibilities. With a lack of detailed information on structural integrity, inspections, and emergency action plans, there is a pressing need for a comprehensive risk assessment and management approach to safeguard this vital water resource for the surrounding community and the environment.

Dam Data Reference
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.
