Summary
Owned and regulated by the state of Texas, this earth dam with a buttress core stands at a height of 9 feet and spans a length of 450 feet. With a storage capacity of 70 acre-feet, it plays a crucial role in managing water flow and storage in the region.
Despite its relatively modest size, the dam's importance is underscored by its primary purpose of serving as a water management structure. With a moderate risk assessment rating, the dam is equipped with an uncontrolled spillway and a single outlet gate. While its hazard potential and condition assessment remain unavailable, the dam's presence highlights the intricate network of water resource infrastructure that supports both historical sites and environmental conservation efforts in the area.
As a part of the Galveston District, the Washington On The Brazos State Historic Site Dam represents a blend of historical significance and modern water management practices. While its specific construction date remains unknown, its role in regulating water flow and storage along the Brazos River showcases the intersection of cultural heritage preservation and environmental stewardship. For water resource and climate enthusiasts, this dam serves as a tangible reminder of the interconnectedness between human history, natural landscapes, and the ongoing need for sustainable water management strategies.

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.
