Summary
This stone-core dam has a height of 22 feet and a length of 1360 feet, providing a storage capacity of 164 acre-feet. With a surface area of 2.82 acres and a drainage area of 0.26 square miles, the pond serves a critical purpose for sediment control in the area.
Despite its high hazard potential and lack of recent condition assessment, Sediment Pond R1-A plays a significant role in managing sediment and runoff in the region. The structure has one outlet gate and no spillway, indicating a need for regular monitoring and maintenance. With a risk assessment rating of "High (2)," there is a clear need for ongoing risk management measures to ensure the safety and effectiveness of the pond in the face of potential climate impacts.
Water resource and climate enthusiasts will find Sediment Pond R1-A an intriguing case study in sediment control and infrastructure management. As a private structure with no state jurisdiction or permitting, the pond represents a unique challenge for ensuring its continued functionality and safety. Its location within the Fort Worth District and proximity to the Roseborough Creek highlight the interconnectedness of water resources and climate resilience in this area of Texas.

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.
