Summary
The dam stands at a height of 22 feet with a length of 500 feet, providing a maximum storage capacity of 73 acre-feet. Despite its relatively small size, the dam is considered to have a high risk potential, highlighting the importance of proper management and maintenance practices.
Situated along the TR-Lampasas River, Mccasland Lake Dam does not have a spillway and is equipped with only one outlet gate. While the dam is not regulated by the state and has not been rated for its condition assessment, it does undergo regular inspections and is permitted for operation by the state. The risk management measures for the dam remain unspecified, underscoring the need for continued monitoring and assessment in order to mitigate potential hazards and ensure the safety of the surrounding area's water resources and environment.
With its strategic location and critical role in providing water supply, Mccasland Lake Dam serves as a vital infrastructure component in the region. As climate change continues to impact water resources and weather patterns, the dam's significance in safeguarding water availability and quality becomes increasingly pronounced, emphasizing the importance of proactive risk management and sustainable practices 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.
