About this dam

East Fork Above Lavon Ws Scs Site 8a Dam

The East Fork Above Lavon WS SCS Site 8a Dam, located in McKinney, Texas, is a key structure designed by the USDA NRCS for flood risk reduction along the Haw Branch river. Completed in 1969, this earth dam stands at a height of 44 feet with a length of 1688 feet, providing a storage capacity of 1795 acre-feet and serving multiple purposes including fire protection, stock watering, and recreation.

Managed by local government authorities and regulated by the Texas Commission on Environmental Quality, the dam is inspected every 5 years and currently has a fair condition assessment. Equipped with a spillway width of 130 feet and outlet gates including a slide and two uncontrolled gates, the East Fork Dam is designed to handle moderate risk levels in case of emergencies. Despite its age, the dam continues to play a crucial role in protecting the surrounding area from potential flooding events.

For water resource and climate enthusiasts, the East Fork Above Lavon WS SCS Site 8a Dam serves as a fascinating example of sustainable infrastructure that has stood the test of time. With its strategic location and design, this dam showcases the importance of proactive measures in managing water resources and mitigating flood risks in a dynamic environment like Texas. Its history, design features, and ongoing maintenance efforts make it a valuable asset in the region's water management system.

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 East Fork Above Lavon Ws Scs Site 8a Dam

Where does the data for East Fork Above Lavon Ws Scs Site 8a 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.
