Summary
Although it lacks a spillway, the dam has one outlet gate and is not regulated by the state, posing a high risk due to its condition being unrated and lacking emergency preparedness measures.
Situated on TR-Salt Creek, the Allen North Lake Dam serves as a crucial structure for water resource management in the region. Despite being privately owned and not under state jurisdiction, the dam plays a significant role in storing water and mitigating the risk of flooding in the area. With a notable history dating back to 1972, the dam's design by an unknown designer and its unique buttress core type add to its appeal for water resource and climate enthusiasts interested in infrastructure.
While the dam's hazard potential is not available and its risk assessment is deemed high, the lack of detailed information on its condition and emergency preparedness raises concerns for the surrounding community. As a part of the Fort Worth District and with no designated inspection frequency or assessment date, the Allen North Lake Dam stands as a reminder of the importance of monitoring and maintaining critical infrastructure to ensure the safety and resilience of water resources in the face of climate challenges.

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.
