Summary

The dam, primarily designed for purposes other than flood control or hydroelectric power generation, stands at a height of 37.15 feet and spans a length of 316 feet. It harnesses a maximum storage capacity of 26 acre-feet and features an uncontrolled spillway with a width of 54 feet.

Managed by the Texas Commission on Environmental Quality (TCEQ), Lincolnshire Dam No 1 is subject to state regulations, permitting, inspection, and enforcement. The dam's condition has been assessed as fair, with a moderate risk rating assigned to it. Last inspected in February 2014, the dam is designated for inspection every 5 years to ensure its structural integrity and safety.

While the dam poses a moderate risk, its hazard potential and emergency action plan status are not available. The dam's associated structures, if any, remain unlisted, and its emergency preparedness measures are not fully detailed. Despite these uncertainties, Lincolnshire Dam No 1 continues to play a vital role in managing the flow of an unnamed tributary of Walnut Creek in the Galveston District of Texas, highlighting the importance of monitoring and maintaining water resources in the face of changing climate conditions.

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.
