Evans Lake Dam dam
Evans Lake Dam
Evans Lake Dam, located in Denton, Texas, is a privately owned recreational dam that was completed in 1964. Standing at a height of 39 feet with a length of 560 feet, this earth dam on the TR-Clear Creek serves as a popular spot for outdoor activities and water sports. With a storage capacity of 218 acre-feet and a surface area of 12 acres, the dam provides a picturesque setting for visitors to enjoy.
Managed by the Texas Commission on Environmental Quality (TCEQ), Evans Lake Dam is regulated, inspected, and enforced by the state to ensure its safety and compliance with regulations. Despite being rated as having a high risk potential, the dam's condition assessment is currently not rated. However, with one outlet gate and no spillway, the dam's design features a buttress core type and serves primarily for recreational purposes, making it a valuable asset for water resource and climate enthusiasts in the area.
While the dam's hazard potential and risk assessment are marked as "Not Available" and "High (2)" respectively, the lack of recent inspection data and maintenance records raises concerns about its overall safety and condition. With no Emergency Action Plan (EAP) in place and limited information on its risk management measures, there is a need for increased monitoring and oversight to ensure the integrity of Evans Lake Dam and protect the surrounding community and environment from potential hazards. For water resource and climate enthusiasts, this serves as a reminder of the importance of proper dam maintenance and emergency preparedness in safeguarding our water infrastructure.

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 Evans Lake Dam
Where does the data for Evans 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.
