East Fork Above Lavon Ws Scs Site 34 Dam dam
East Fork Above Lavon Ws Scs Site 34 Dam
The East Fork Above Lavon WS SCS Site 34 Dam, located in McKinney, Texas, is a key flood risk reduction structure designed by the USDA NRCS and completed in 1966. With a height of 46 feet and a length of 1180 feet, this earth dam plays a critical role in protecting the surrounding area from potential flooding events along the TR-East Fork Trinity River. The dam has a normal storage capacity of 127 acre-feet and a maximum storage capacity of 567 acre-feet, serving multiple purposes such as fire protection, irrigation, and recreation in addition to flood risk reduction.
Managed by the TCEQ and with state jurisdiction, the East Fork Above Lavon WS SCS Site 34 Dam is subject to regular inspections and enforcement measures to ensure its structural integrity and safety. The dam features a slide gate outlet for water control and does not have a spillway, highlighting its unique design for handling water flow. Although the hazard potential and condition assessment are not available, the dam's risk assessment is classified as high, indicating the importance of ongoing monitoring and risk management measures for this critical infrastructure. With its strategic location and significant impact on the local water resources, the East Fork Above Lavon WS SCS Site 34 Dam stands as a vital asset in the region's water resource and climate resilience efforts.
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 34 Dam
Where does the data for East Fork Above Lavon Ws Scs Site 34 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.
