Summary
Completed in 1996, this dam stands at a height of 20.35 feet and has a storage capacity of 134 acre-feet. The pond covers a surface area of 4.6 acres and has a drainage area of 0.13 square miles, with an uncontrolled spillway width of 60 feet.
Operated by the Mine Safety and Health Administration, Sedimentation Pond 027 plays a crucial role in managing sediment and water flow in the Tri-Navasota River. Despite its moderate risk assessment rating, the condition of the dam has not been officially assessed, and its emergency action plan status is currently unknown. With its location near a river and its importance for sediment control, this dam serves as a key infrastructure in the region for water resource and climate enthusiasts to monitor and study.
As climate change continues to impact water resources, the role of structures like Sedimentation Pond 027 becomes increasingly vital in maintaining water quality and managing sediment runoff. With the potential for increased frequency and intensity of extreme weather events, the proper maintenance and monitoring of this dam are essential to ensure its effectiveness and safety. As enthusiasts in this field, it is important to stay informed about the condition and operation of such structures to contribute to the preservation and sustainable management of water resources in the region.

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.
