J. D. Dam dam
J. D. Dam
J. D. Dam, located in Coconino, Arizona, is a Federal-owned structure managed by the Forest Service with a primary purpose of serving as a Fish and Wildlife Pond. Built in 1915, this Earth-type dam stands at a height of 21 feet and has a maximum storage capacity of 70 acre-feet. It sits on J D Dam Wash near Sycamore Creek, providing vital water resources for fire protection, livestock, recreation, and aquatic habitats.
With a low hazard potential and moderate risk assessment, J. D. Dam plays a crucial role in managing water resources in the region. The dam's uncontrolled spillway and rock foundations contribute to its structural integrity, while its proximity to Cottonwood ensures easy access for monitoring and maintenance. Despite its age, J. D. Dam continues to support the surrounding ecosystem and serves as a testament to early water management efforts in Arizona.
As a key feature in the Los Angeles District's water infrastructure, J. D. Dam undergoes regular inspections and is well-maintained by the Forest Service. With a focus on fish and wildlife conservation, this historic dam stands as a reminder of the importance of sustainable water resource management in the face of climate change and increasing water demands.

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 J. D. Dam
Where does the data for J. D. 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.
