Lake Tanglewood Dam dam
Lake Tanglewood Dam
Lake Tanglewood Dam in Randall, Texas, is a crucial structure designed for flood risk reduction along the Prairie Dog Town Fork Red River. Built in 1965, this earth dam stands at 85 feet tall and stretches 1500 feet in length, with a storage capacity of 15,850 acre-feet. The dam serves multiple purposes, including flood risk reduction and recreation, making it a vital asset for both environmental protection and community enjoyment.
Managed by private owners and regulated by the Texas Commission on Environmental Quality (TCEQ), Lake Tanglewood Dam has undergone periodic inspections and modifications to ensure its safety and efficiency. With an uncontrolled spillway and two outlet gates, the dam is equipped to handle a maximum discharge of 291,522 cubic feet per second. Despite its moderate risk assessment, the dam has not been rated for its current condition, highlighting the need for ongoing monitoring and maintenance to safeguard the surrounding area and its inhabitants.
As a significant feature in the region's water resource and climate management efforts, Lake Tanglewood Dam serves as a reminder of the delicate balance between human development and environmental preservation. With its rich history of construction and continuous regulatory oversight, the dam stands as a testament to the collaborative efforts required to protect communities from potential flood hazards while also providing a space for recreational activities and outdoor enjoyment.

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 Lake Tanglewood Dam
Where does the data for Lake Tanglewood 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.
