About this dam

Tehuacana Creek Ws Scs Site 18 Dam

Located in McLennan County, Texas, the Tehuacana Creek WS SCS Site 18 Dam is a vital structure designed by the USDA NRCS for flood risk reduction along the TR-Little Tehuacana Creek. Completed in 1969, this earth dam stands at a height of 33 feet and stretches 4500 feet in length, providing a maximum storage capacity of 1534 acre-feet. With a normal storage of 141 acre-feet and a drainage area of 2.4 square miles, this dam plays a crucial role in mitigating flood risks in the region.

Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), the Tehuacana Creek WS SCS Site 18 Dam is equipped with uncontrolled spillways and outlet gates for efficient water management. Despite being assessed as in fair condition, with a moderate risk level, the dam has not undergone any recent modifications and is inspected every 5 years to ensure its structural integrity. With a history of serving multiple purposes such as fire protection, stock, or small fish pond, the dam remains a key component of the water resource infrastructure in the area.

With its strategic location and significant contribution to flood risk reduction, the Tehuacana Creek WS SCS Site 18 Dam stands as a testament to effective water resource management in Texas. As climate change continues to impact the region, this dam serves as a crucial line of defense against potential disasters, highlighting the importance of ongoing inspection and maintenance to ensure its continued functionality. For water resource and climate enthusiasts, this dam represents a beacon of resilience and preparedness in the face of environmental challenges.

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 Tehuacana Creek Ws Scs Site 18 Dam

Where does the data for Tehuacana Creek Ws Scs Site 18 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.
