Summary
Standing at 31 feet high and stretching 740 feet in length, this dam holds a maximum storage capacity of 400 acre-feet, with a normal storage capacity of 312 acre-feet. The dam overlooks the TR-Little Saline Creek and is regulated by the state of Texas through the permitting and inspection process.
With a high hazard potential rating, Neill Lake Dam's condition assessment is currently not rated, highlighting the importance of regular monitoring and maintenance. Despite lacking a spillway, the dam features one outlet gate for water release. The dam is not under the jurisdiction of any federal agency, emphasizing the responsibility of the private owner to ensure the safety and integrity of the structure. The risk assessment for Neill Lake Dam is classified as high, indicating the need for proactive risk management measures to safeguard against potential threats.
Enthusiasts of water resources and climate will find Neill Lake Dam an intriguing structure, showcasing the vital role of dams in providing water supply for communities. Its location in Texas and association with the TR-Little Saline Creek add to its significance in the region's water infrastructure. As a privately-owned dam with state permitting and inspection requirements, Neill Lake Dam serves as a reminder of the collaborative efforts needed to ensure the safety and sustainability of water resources in the face of evolving climate 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.
