Heron Dike dam
Heron Dike
Heron Dike, located in Rio Arriba, New Mexico, along Willow Creek, is a key Federal structure managed by the Bureau of Reclamation for irrigation purposes. Built in 1971, this earth dam stands at 94 feet high and has a storage capacity of 429,646 acre-feet, serving as a vital water supply source for the region. Despite its high hazard potential and condition assessment being unavailable, Heron Dike plays a crucial role in water management in the area.
With a hydraulic height of 85 feet and a surface area of 6,148 acres, Heron Dike provides essential water resources for irrigation and water supply needs. The dam's primary owner, the Bureau of Reclamation, is responsible for its design, construction, regulation, and operation, ensuring its structural integrity and safety. Although it lacks a spillway, the dam's risk assessment is categorized as high, highlighting the importance of continued monitoring and management to prevent potential hazards.
In the event of an emergency, the dam's Emergency Action Plan (EAP) is expected to meet guidelines, with the last revision dated back to October 2019. As a critical infrastructure for water management in the region, Heron Dike underscores the importance of proactive risk management and maintenance to safeguard water resources and protect against potential risks associated with high hazard structures like this one.
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 Heron Dike
Where does the data for Heron Dike 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 High 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.
