East Fork Above Lavon Ws Scs Site 11 Dam dam
East Fork Above Lavon Ws Scs Site 11 Dam
East Fork Above Lavon WS SCS Site 11 Dam, located in Collin, Texas, serves as a crucial structure for flood risk reduction along the TR-Honey Creek. Built in 1952 by the USDA NRCS, this earth dam stands at a height of 48 feet and spans 1303 feet in length, providing a storage capacity of 1277 acre-feet. With a normal storage capacity of 260 acre-feet and a maximum discharge rate of 6902 cubic feet per second, the dam contributes to irrigation, fire protection, and recreational activities in the area.
Managed by the local government and regulated by the TCEQ, the East Fork Above Lavon WS SCS Site 11 Dam has been assessed as structurally sound and in satisfactory condition as of April 2021. The spillway, an uncontrolled type, spans 201 feet and ensures the safe release of excess water during high-flow events. With one slide gate and two uncontrolled outlets, the dam remains well-prepared for emergencies, although additional risk management measures may be considered to further enhance its resilience.
Overall, the East Fork Above Lavon WS SCS Site 11 Dam presents a moderate risk level (3) and is subject to a regular inspection frequency of every five years. With its strategic location and vital role in flood control and water management, this dam exemplifies the importance of sustainable infrastructure in safeguarding communities and ecosystems against the impacts of climate change and water resource challenges.
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 11 Dam
Where does the data for East Fork Above Lavon Ws Scs Site 11 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.
