Summary

The dam stands at a height of 16 feet with a length of 1070 feet, providing a storage capacity of 204 acre-feet and a normal storage of 108 acre-feet. The dam is situated on the MARTIN BRANCH stream within the Fort Worth District, and is regulated by the Texas Commission on Environmental Quality (TCEQ).

Despite its low hazard potential, the dam's condition assessment in 2018 was rated as poor, and it has undergone structural modifications in 1998, 2001, and 2002. Elm Pond Dam features controlled outlet gates and a spillway width of 36 feet, with a maximum discharge capacity of 562 cubic feet per second. The inspection frequency for the dam is every 5 years, with the last inspection conducted in January 2018.

Water resource and climate enthusiasts interested in Elm Pond Dam can appreciate its role in supporting fish and wildlife habitats in the area, as well as the ongoing efforts to ensure its safety and functionality through regular inspections and maintenance. The dam's location and design provide valuable insights into the management of water resources and the balancing of environmental conservation with infrastructure development in the region. The history and characteristics of Elm Pond Dam make it a fascinating case study for those passionate about the intersection of water management, ecosystem conservation, and climate resilience.

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.
