Summary
Standing at a height of 38 feet with a length of 1300 feet, the dam holds a storage capacity of 850 acre-feet and covers a surface area of 30 acres. It spans the TR-Nebletts Creek and is under the jurisdiction of the Texas Commission on Environmental Quality (TCEQ) for regulation, permitting, inspection, and enforcement.
The dam features an uncontrolled spillway with a width of 140 feet and two uncontrolled outlet gates. While the hazard potential and condition assessment are not available, the risk assessment indicates a moderate risk level. The last inspection of the dam was conducted in 1988, and its emergency action plan status and risk management measures remain undisclosed. The dam's location in a picturesque setting makes it a hidden gem for water resource and climate enthusiasts to explore and appreciate.
Despite the lack of recent data on the dam's condition and emergency preparedness, Hideaway Hills Lake Dam stands as a testament to engineering ingenuity and serves as a vital component of the local recreational ecosystem. With its tranquil waters and scenic surroundings, the dam offers a serene retreat for visitors seeking to connect with nature and enjoy the beauty of Texas's water resources. As enthusiasts of water resource management and climate conservation, exploring this hidden oasis can provide valuable insights into the intersection of human engineering and natural landscapes.

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.
