Summary
This Earth-type dam serves primarily as a Fish and Wildlife Pond, with additional purposes including Fire Protection, Stock, Recreation, and Small Fish Pond. The dam stands at a height of 24 feet and has a length of 800 feet, providing storage capacity of 306 acre-feet.
Despite its age, Cullum Dam remains in good condition with a high hazard potential rating. It lacks a spillway and has no locks, with a single outlet gate for water release. The dam's risk assessment is categorized as high, indicating the need for careful monitoring and maintenance to ensure its continued safety and functionality. While it is not under state regulation or jurisdiction, the dam is subject to state permitting and inspection requirements.
As a vital water resource for the area, Cullum Dam plays a crucial role in supporting local wildlife and recreational activities. Its strategic location along TR-LONG CREEK underscores its significance in maintaining ecological balance and providing essential water storage for various purposes. With its rich history and continued importance, Cullum Dam stands as a testament to effective water resource management and conservation efforts in Texas.

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.
