East Fork Above Lavon Ws Scs Site 39 Dam dam
East Fork Above Lavon Ws Scs Site 39 Dam
East Fork Above Lavon WS SCS Site 39 Dam, located in Grayson County, Texas, stands as a testament to effective flood risk reduction measures put in place since its completion in 1966. Owned by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), this earth dam with a height of 54 feet and a length of 2214 feet serves the primary purpose of flood risk reduction along the East Prong Whites Creek. With a storage capacity of 3237 acre-feet and a maximum discharge of 6355 cubic feet per second, the dam plays a crucial role in managing water flow and safeguarding the surrounding areas from potential flooding.
Managed by the Natural Resources Conservation Service, the East Fork Above Lavon WS SCS Site 39 Dam has been assessed to be in fair condition as of April 2021, with a moderate risk level assigned. The dam features an uncontrolled spillway and outlet gates, demonstrating a commitment to effective water management practices. Despite its relatively small surface area of 34 acres, the dam covers a drainage area of 6.25 square miles, showcasing its importance in maintaining hydrological balance in the region. With regular inspections and a designated emergency action plan, the dam ensures that it meets the necessary safety guidelines and remains prepared for any potential risks.
Overall, the East Fork Above Lavon WS SCS Site 39 Dam stands as a vital infrastructure component in the region, serving as a reliable flood risk reduction measure with a focus on water resource management and climate resilience. As climate change continues to impact water systems, dams like this play a crucial role in mitigating risks and ensuring the safety and well-being of local communities. The collaborative efforts of various agencies and stakeholders involved in the operation and maintenance of the dam underscore the importance of proactive measures in safeguarding water resources for future generations.
Dam data reference
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.

About East Fork Above Lavon Ws Scs Site 39 Dam
Where does the data for East Fork Above Lavon Ws Scs Site 39 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.
