Summary

Constructed in 1984, this earth dam structure stands at a height of 11 feet, with a storage capacity of 97 acre-feet. The pond covers a surface area of 7 acres and is situated along the TR-Navasota River, in the heart of Leon County.

Despite being privately owned and not regulated by the state, Sedimentation Pond No 5 plays a significant role in the local ecosystem. The dam, with its buttress core design, serves as a vital component in controlling the discharge of water and sediment into the river. However, with no spillway in place, the potential for flooding and environmental hazards remains a concern, especially given the high risk rating of 2 assigned to the structure.

While the condition of Sedimentation Pond No 5 is not rated, and no recent inspections have been reported, the site poses a certain level of risk due to its high hazard potential and lack of management measures in place. As water resource and climate enthusiasts, it is imperative to monitor and address any potential safety concerns associated with this crucial structure to ensure the protection of the local environment and community.

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.
