East Fork Above Lavon Ws Scs Site 9 Dam dam
East Fork Above Lavon Ws Scs Site 9 Dam
East Fork Above Lavon WS SCS Site 9 Dam is a vital flood risk reduction infrastructure located in McKinney, Texas, along the TR-HONEY CREEK. Built in 1951 by the USDA NRCS, this earth dam stands at a height of 43 feet and spans 1456 feet in length. With a storage capacity of 832 acre-feet and a normal storage of 150 acre-feet, the dam serves multiple purposes including fire protection, stock, or small fish pond, flood risk reduction, and recreation.
Managed by the Texas Commission on Environmental Quality (TCEQ), the East Fork Above Lavon WS SCS Site 9 Dam is classified as fair in condition assessment and has a moderate risk level (3). The dam features an uncontrolled spillway, outlet gates including slide and uncontrolled gates, and is regularly inspected every 5 years. In case of emergencies, the dam has an emergency action plan in place, although details on its preparedness are not available.
With its historical significance and continued role in mitigating flood risks in the region, the East Fork Above Lavon WS SCS Site 9 Dam highlights the importance of proper infrastructure management for water resources and climate enthusiasts. As a key structure in Collin County, Texas, this dam serves as a testament to the collaborative efforts between local governments, regulatory agencies, and design authorities in ensuring the safety and protection of communities along the TR-HONEY CREEK watershed.

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 9 Dam
Where does the data for East Fork Above Lavon 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.
