Summary
Built in 1960, this earth dam stands at a height of 22 feet and has a length of 450 feet, providing a maximum storage capacity of 500 acre-feet. Despite its small surface area of 30 acres, the dam plays a crucial role in water management in the region.
Operated under the jurisdiction of TCEQ and subject to state regulations, Nail Lake No 1 Dam has not been rated for its condition assessment, but is considered to have a high hazard potential. With no spillway and limited outlet gates, the dam poses a potential risk to the surrounding areas in case of emergency situations. The risk assessment for this dam has been categorized as high, highlighting the importance of regular inspections and maintenance to ensure its safety and reliability in the face of changing climate conditions.
As a key structure in the water resource infrastructure of the area, Nail Lake No 1 Dam serves as a reminder of the importance of sustainable water management practices and the need for proactive risk management measures in the face of potential climate-related challenges. Its location along the Foyle Creek and its critical role in providing water supply underscore the significance of maintaining and monitoring this dam to safeguard both the local community and the environment in the years to come.

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.
