Greenbelt Dam dam
Greenbelt Dam
Greenbelt Dam, located in Donley County, Texas, was completed in 1968 and serves as a vital resource for both recreation and water supply. Managed by local government authorities, the dam spans 8,300 feet in length and stands at a height of 111 feet, with a storage capacity of 100,500 acre-feet. The dam is situated on the Salt Fork Red River and is regulated by the Texas Commission on Environmental Quality (TCEQ), ensuring proper inspection, permitting, and enforcement measures are in place to safeguard the structure and surrounding environment.
With a surface area of 2,020 acres and a drainage area of 266 square miles, Greenbelt Dam plays a crucial role in water management and flood control for the region. The dam features an uncontrolled spillway and outlet gates for water release, with a maximum discharge capacity of 190,675 cubic feet per second. Despite being rated in fair condition as of the last assessment in 2017, the dam poses a moderate risk level for potential hazards, highlighting the importance of ongoing monitoring and risk management measures to ensure the safety and integrity of this essential water resource infrastructure.
For water resource and climate enthusiasts, Greenbelt Dam represents a significant engineering achievement that not only provides essential water storage and recreational opportunities but also underscores the importance of proactive maintenance and risk mitigation strategies in the face of changing environmental conditions. As a key component of the region's water supply infrastructure, the dam serves as a critical lifeline for local communities and ecosystems, showcasing the interconnected relationship between water resources, climate resilience, and sustainable development.

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 Greenbelt Dam
Where does the data for Greenbelt 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.
