Green Reservoir No 1 Dam dam
Green Reservoir No 1 Dam
Green Reservoir No 1 Dam, located in Shackelford County, Texas, was completed in 1960 for the primary purpose of irrigation. The dam, standing at a height of 24 feet and stretching 525 feet in length, holds a maximum storage capacity of 163 acre-feet. Situated on McDowell Creek, this earth dam with a buttress core type plays a crucial role in providing water for agricultural needs in the region.
Although the dam does not have a spillway, it is equipped with one outlet gate for water release. With a surface area of 10 acres and a normal storage capacity of 68 acre-feet, the dam serves as a vital resource for fire protection, stock watering, and small fish pond maintenance in addition to irrigation purposes. While the risk assessment for the dam categorizes it as high risk, measures for risk management and emergency preparedness are not currently available, highlighting the need for continued monitoring and maintenance to ensure its integrity and safety.
As a privately owned structure, Green Reservoir No 1 Dam falls under state regulation for permitting and inspection, but not enforcement. The dam, managed by its private owner, contributes significantly to the local water resource management and climate resilience efforts. With its strategic location and purposeful design, this dam stands as a testament to the importance of sustainable water infrastructure in supporting agricultural activities and environmental conservation in the region.

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 Green Reservoir No 1 Dam
Where does the data for Green Reservoir 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.
