Phillips North Lake Dam dam
Phillips North Lake Dam
Phillips North Lake Dam, located in Denton, Texas, was completed in 1970 and serves as both a recreational spot and a water supply source. Designed by Sutton & Crow, this earth dam stands at 26 feet high and spans 670 feet in length, with a storage capacity of 145 acre-feet. Despite its small drainage area of 0 square miles, the dam plays a crucial role in regulating the flow of the TR-Garza Little Elm Reservoir.
Managed by a private owner, Phillips North Lake Dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections, enforcement, and permitting processes. The dam's hazard potential is not available, but it is classified as having a high risk (2). With no spillway and one outlet gate, the dam's condition is currently not rated, highlighting the need for ongoing risk management measures and emergency preparedness.
For water resource and climate enthusiasts, Phillips North Lake Dam presents an intriguing case study in dam engineering and management. Its dual purpose of recreation and water supply, combined with its unique design features and risk assessment, make it a focal point for understanding the importance of maintaining infrastructure in the face of changing environmental conditions. As the dam continues to play a vital role in the local ecosystem, ongoing monitoring and maintenance efforts will be crucial to ensure its long-term sustainability and resilience in the face of potential hazards.

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 Phillips North Lake Dam
Where does the data for Phillips North 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.
