Boynton Lake Dam dam
Boynton Lake Dam
Boynton Lake Dam, also known as Scout Dam, is a Federal-owned structure located in Apache County, Arizona. Built in 1974 by the USDA NRCS, this earth dam on Mineral Creek stands at a height of 27 feet and serves multiple purposes including fire protection, stock containment, and recreation. The dam has a maximum storage capacity of 200 acre-feet and covers a drainage area of 10 square miles.
With a controlled spillway width of 125 feet, Boynton Lake Dam has a low hazard potential and is currently in a not rated condition assessment. Despite its age, the dam has not been modified since its completion and is inspected every 10 years to ensure its safety. The risk assessment for the dam is very high, indicating the importance of ongoing monitoring and management measures to mitigate any potential risks associated with its operation.
Situated in a picturesque location near Concho, Arizona, Boynton Lake Dam offers a serene setting for recreation enthusiasts and water resource management professionals alike. As part of the Forest Service's infrastructure, the dam plays a crucial role in providing water storage for various purposes while also contributing to the conservation of fish and wildlife in the area. Its strategic design and construction by the Natural Resources Conservation Service make it a valuable asset for the community, highlighting the intersection of water resource management and climate resilience in this region.
Dam data reference
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 Boynton Lake Dam
Where does the data for Boynton 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 Low 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.
