Summary
The dam is an earth structure with a height of 18 feet and a length of 750 feet, serving primarily for agricultural purposes. Located on the TR-Little Cypress Bayou, this reservoir plays a crucial role in providing water for irrigation in the region.
Despite its relatively small size, Holloway Lake has a high hazard potential and is classified as having a risk level of 2, indicating the need for careful monitoring and maintenance. While the dam has not been rated for its condition, it is important for water resource and climate enthusiasts to stay informed about the ongoing management and risk assessment measures in place for this structure. With no spillway and limited discharge capacity, the reservoir's ability to handle extreme weather events and potential flood risks is a critical concern for the surrounding area.
With no federal oversight or funding, Holloway Lake is solely regulated and inspected by the state of Texas. While it may not be as well-known as larger reservoirs, its significance in providing essential water resources for irrigation underscores the importance of maintaining its structural integrity and ensuring proper risk management strategies are in place. Water resource and climate enthusiasts should pay attention to developments surrounding this reservoir to understand the challenges and opportunities it presents for sustainable water management in the region.

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.
