Summary
With a height of 16 feet and a length of 1000 feet, the dam holds a storage capacity of 72 acre-feet, making it a crucial water resource for the area. Despite being unregulated by the state and with no designated spillway, the dam has a high hazard potential, emphasizing the importance of regular inspections and maintenance.
This dam, situated on the TR-N Fork Chambers Creek, serves as a vital irrigation source for the region, with a normal storage capacity of 67 acre-feet and an outlet gate for water release. While the dam itself is not rated for condition assessment, its risk assessment is classified as high (2), indicating potential safety concerns that need to be addressed. The Fort Worth District oversees this structure, which has not been modified in recent years, highlighting the need for ongoing monitoring and risk management measures to ensure its safety and effectiveness for water resource management in the area.
Despite the lack of state regulation and enforcement, Buck Ranch Lake No 4 Dam plays a critical role in sustaining agricultural activities in Johnson County, Texas. With its strategic location and significant storage capacity, this earth dam continues to be a valuable asset for irrigation purposes. As climate change impacts water resources, the importance of maintaining and managing structures like this dam becomes increasingly essential for ensuring water security and resilience in the face of evolving environmental 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.
