Lavon Bluff Dam dam
Lavon Bluff Dam
Lavon Bluff Dam, located in Collin County, Texas, is a privately owned structure regulated by the Texas Commission on Environmental Quality (TCEQ). Standing at a height of 18 feet and with a total length of 1090 feet, the dam serves a primary purpose that is classified as "Other" and is of a unique design known as a Buttress dam. The dam has a storage capacity of 430 acre-feet, with normal storage levels reaching 260 acre-feet.
Despite its significant storage capacity, the dam's condition assessment is listed as "Poor," indicating a need for maintenance and potential upgrades to ensure its continued safety and functionality. The dam has an uncontrolled spillway with a width of 104 feet, and its hazard potential is currently labeled as "Not Available." The risk assessment for the dam is considered moderate, highlighting the importance of ongoing monitoring and management to mitigate potential hazards and ensure the safety of the surrounding area.
Water resource and climate enthusiasts are likely to be interested in Lavon Bluff Dam due to its unique design and the challenges it faces in maintaining its structural integrity. The dam's location in Texas, a state prone to extreme weather events, underscores the importance of proper maintenance and oversight to protect against potential risks. With its current condition assessment categorized as "Poor," there is a pressing need for attention and resources to address any vulnerabilities and ensure the continued functionality of this vital water resource infrastructure.
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 Lavon Bluff Dam
Where does the data for Lavon Bluff 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.
