Hog Wallow dam
Hog Wallow
Hog Wallow, located in Apache County, Arizona, is a private Fish and Wildlife Pond constructed in 1908 with a dam height of 7 feet and a length of 392 feet. The dam has a storage capacity of 1000 acre-feet and serves multiple purposes including fire protection, stock watering, irrigation, and recreation. Situated along the Little Colorado River, the dam's primary source agency is the Arizona Department of Water Resources, with state regulatory oversight for permitting, inspection, and enforcement.
With a low hazard potential and a moderate risk assessment rating, Hog Wallow dam remains in good condition, though it has not been rated recently. The dam features an uncontrolled spillway with a width of 12 feet and has a drainage area of 4 square miles. Despite not being inspected since 2009, the dam is regularly monitored for any potential risks or issues. In case of emergencies, the dam does not have an Emergency Action Plan in place, but the risk management measures are being actively considered to ensure the safety of the surrounding area.
Overall, Hog Wallow serves as a vital resource for the local wildlife and recreational activities in the area. With its historical significance and multi-purpose utility, the dam continues to be an essential component of the water resource infrastructure in Apache County, Arizona. Enthusiasts of water resources and climate will find the unique characteristics and management aspects of Hog Wallow to be both intriguing and informative in understanding the intersection of human development and environmental conservation.

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 Hog Wallow
Where does the data for Hog Wallow 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.
