Summary

Designed by the USDA NRCS, this dam stands at a height of 32 feet and has a storage capacity of 44 acre-feet. With a condition assessment of 'Not Rated' and a hazard potential deemed 'Not Available,' this structure presents a high risk level of 2.

While the dam lacks certain regulatory oversight such as state jurisdiction and enforcement, it is permitted and inspected by the state of Texas. The risk assessment for Browning Trust No 1 Gss highlights the need for effective risk management measures to mitigate potential hazards. With a spillway type listed as 'None' and no inundation maps prepared, it is essential for the owners to prioritize safety and emergency preparedness for this structure in the event of an unexpected incident. Despite the lack of certain data points, the risk level classification of 2 underscores the importance of proactive monitoring and maintenance to ensure the safety and integrity of this dam for the surrounding community and water resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
