East Fork Above Lavon Ws Scs Site 1a Dam dam
East Fork Above Lavon Ws Scs Site 1a Dam
Located in McKinney, Texas, the East Fork Above Lavon WS SCS Site 1a Dam stands as a testament to flood risk reduction efforts in the region. Built in 1957 by the USDA NRCS, this earth dam boasts a height of 54 feet and a hydraulic height of 52 feet, with a length of 1200 feet. The dam has a storage capacity of 842 acre-feet, serving as a crucial flood control structure for the surrounding area.
Managed by the local government and regulated by the Texas Commission on Environmental Quality, the East Fork Dam plays a vital role in protecting the community from potential flooding events. With a spillway width of 234 feet and a maximum discharge of 9834 cubic feet per second, the dam is equipped to handle significant water flow during heavy rain periods. Despite being classified as having a moderate risk level, the dam's condition is assessed as satisfactory, ensuring its continued effectiveness in flood mitigation efforts.
Surrounded by the scenic Wilson Creek, the East Fork Dam not only serves a functional purpose but also offers recreational opportunities for locals and visitors alike. With its strategic location and robust design, this dam stands as a symbol of resilience and proactive water resource management in the face of changing climate patterns.
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 1a Dam
Where does the data for East Fork Above Lavon Ws Scs Site 1a 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.
