Twin Lakes No 1 Dam dam
Twin Lakes No 1 Dam
Twin Lakes No 1 Dam, located in Denton, Texas, is a privately owned earth dam primarily used for recreation purposes. Completed in 1970, this dam stands at a height of 11 feet and has a length of 420 feet, with a storage capacity of 100 acre-feet and a surface area of 5.5 acres. The dam is situated on the TR-Milam Creek and is regulated by the Texas Commission on Environmental Quality (TCEQ), ensuring that it meets state inspection and enforcement standards.
The dam features an uncontrolled spillway with a width of 55 feet and an outlet gate that is also uncontrolled. Despite having a fair condition assessment as of August 2015, the dam poses a moderate risk (rated 3 out of 5) according to the hazard potential assessment. The last inspection was conducted in November 2014, with a scheduled frequency of every 5 years. While there are no associated structures with the dam, it serves as a valuable recreational resource in the area, offering opportunities for water-based activities and enjoyment for both locals and visitors alike.
Water resource and climate enthusiasts will find Twin Lakes No 1 Dam to be an interesting case study in dam management and regulation, showcasing the importance of maintaining infrastructure for both safety and recreational purposes. The dam's location in the Fort Worth District adds to its significance, highlighting the intersection of natural resources and human development in a rapidly growing region. As climate change continues to impact water resources, understanding the role of dams like Twin Lakes No 1 in both mitigating risks and providing valuable services to communities becomes increasingly vital for sustainable water management.

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 Twin Lakes No 1 Dam
Where does the data for Twin Lakes No 1 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.
