Summary

The dam, standing at a height of 24 feet and a length of 458 feet, has a storage capacity of 138 acre-feet and a normal storage of 103 acre-feet. It is situated on the TR-WEST YEGUA CREEK and is under the regulatory jurisdiction of the state, with permitting and inspection processes in place.

Despite being categorized as having a 'High' risk assessment level, with a hazard potential labeled as 'Not Available' and a condition assessment as 'Not Rated', Wolff Gss remains an essential structure for water resource management in the region. The dam does not have a spillway and is equipped with one outlet gate. It is closely monitored by the Natural Resources Conservation Service, although the last inspection date and other critical information are currently not available. The dam plays a crucial role in managing water resources in the area and ensuring the safety of surrounding communities.

As water resource and climate enthusiasts, the data on Wolff Gss provides valuable insight into the infrastructure that supports water management in Texas. The dam's construction and design by the USDA NRCS highlight the collaborative efforts between private entities and government agencies to address water needs. Understanding the risk assessment, storage capacity, and regulatory oversight of Wolff Gss is crucial for maintaining the resilience of water systems in the face of changing climate patterns and increasing water demands.

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.
