Summary
The dam is an earth type with a height of 27 feet and a length of 360 feet, holding a maximum storage of 112 acre-feet of water. Situated on Groves Branch, the dam does not have a spillway and is not regulated by the state.
Despite being classified as having a high risk potential, the condition of Clark Lake Dam is currently not rated. It has not been inspected recently, and there is no emergency action plan in place. The dam does not have a hazard potential rating, and there are no inundation maps prepared for potential flooding scenarios. The dam's purpose and design make it a modest but essential resource for fire protection and water storage in the area, highlighting the importance of regular maintenance and monitoring to ensure its safety and functionality for the community.
For water resource and climate enthusiasts, Clark Lake Dam represents a historic structure that serves multiple purposes in the region. Its construction in the early 20th century reflects the importance of water management and conservation efforts, particularly for fire protection and agricultural needs. As a privately owned dam, it showcases the diverse landscape of water infrastructure in Texas and the unique challenges faced by smaller, non-regulated structures. The risk assessment and lack of recent inspections underscore the ongoing need for attention to these critical assets to prevent potential hazards and ensure sustainable water management practices in the future.

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.
