About this dam

Ne Trib Leon River Ws Scs Site 9 Dam

Ne Trib Leon River WS SCS Site 9 Dam, located in Erath County, Texas, stands as a crucial structure for flood risk reduction along the TR-Sand Branch river. Built in 1967 by the USDA NRCS, this earth dam measures 40 feet in height and spans 1700 feet in length, with a storage capacity of 1059 acre-feet. With a fair condition assessment as of November 2016, the dam features uncontrolled outlets and a spillway width of 102 feet to manage a maximum discharge of 1882 cubic feet per second.

Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Ne Trib Leon River WS SCS Site 9 Dam plays a vital role in protecting the surrounding area from potential flooding events. The dam's location in the city of Highland contributes to safeguarding both residents and infrastructure from water-related hazards, demonstrating its significance in the region's water resource management. As a federally designed structure, it underscores the collaborative efforts between various agencies to ensure the dam's functionality and safety.

Despite its moderate risk assessment level, the dam's strategic design and operational measures indicate a proactive approach to mitigating potential hazards. The regular inspections and state permitting processes underscore a commitment to maintaining the dam's integrity and functionality for long-term flood control purposes. As water resource and climate enthusiasts, understanding the intricacies of structures like Ne Trib Leon River WS SCS Site 9 Dam provides valuable insights into the intersection of engineering, environmental conservation, and community resilience in managing water resources effectively.

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.
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.
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.

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, environmental 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.

FAQ

About Ne Trib Leon River Ws Scs Site 9 Dam

Where does the data for Ne Trib Leon River Ws Scs Site 9 Dam come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Not Available hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
