Summary

Standing at a height of 24 feet with a length of 750 feet, the earth dam holds a storage capacity of 575 acre-feet, primarily utilized for recreational activities. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes state inspections and enforcement to ensure its safety and compliance with regulations.

Over the years, Spring Lake Dam has undergone modifications in 1987 for hydraulic purposes and in 2011 for structural improvements. The dam features one other controlled and two uncontrolled outlet gates, contributing to its overall functionality. Despite its fair condition assessment as of April 2021, the dam is considered to have a hazard potential that is not available, indicating the need for continued monitoring and maintenance to ensure its safety. With a history of collaborative design involving various engineering firms, Spring Lake Dam remains a vital water resource within the McDonald Creek watershed, providing both recreational enjoyment and essential regulatory oversight in the region.

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.
