Rayzor Lake Dam dam
Rayzor Lake Dam
Rayzor Lake Dam, located in Denton, Texas, serves as a vital structure for recreation and water resource management. Constructed in 1968, this earth dam stands at a height of 17 feet and has a hydraulic height of 22 feet, providing a storage capacity of 97 acre-feet. The dam overlooks the TR-DRY FORK river or stream and is under the regulatory jurisdiction of the Texas Commission on Environmental Quality (TCEQ).
With a spillway width of 20 feet and a maximum discharge capacity of 2194 cubic feet per second, Rayzor Lake Dam is equipped to handle potential flooding events. The dam's condition has been assessed as fair, with the last inspection conducted in February 2017. While the hazard potential is not available, the risk assessment indicates a moderate level of risk (3), prompting the need for ongoing risk management measures to ensure the dam's safety and integrity for years to come.
As a private-owned structure, Rayzor Lake Dam plays a crucial role in providing recreational opportunities and contributing to the overall water resource management in the region. With its scenic surroundings and strategic location, this dam stands as a testament to the importance of sustainable infrastructure development in safeguarding our natural resources amidst a changing climate landscape.

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 Rayzor Lake Dam
Where does the data for Rayzor Lake 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.
