Asamera Cannon Mine Tailings Dam dam
Asamera Cannon Mine Tailings Dam
The Asamera Cannon Mine Tailings Dam, located in Wenatchee, Washington, was completed in 1986 for flood risk reduction on Dry Gulch. This earth dam stands at a hydraulic height of 350 feet and a structural height of 340 feet, with a length of 1150 feet. It has a storage capacity of 3300 acre-feet and covers a surface area of 2500 acres. The dam is owned privately and regulated by the Washington Department of Ecology, with state permitting, inspection, and enforcement in place.
With a hazard potential rated as high, the dam's condition was last assessed as satisfactory in January 2018. Regular inspections are conducted every five years, with the most recent one taking place in September 2017. Despite its high hazard potential, the dam meets guidelines for emergency action preparedness, although the last revision of its emergency action plan was in October 2021. The dam's risk assessment, inundation maps, and risk management measures are currently not available.
Water resource and climate enthusiasts will find the Asamera Cannon Mine Tailings Dam a significant structure in flood risk mitigation in the area. Its design and operational aspects, along with its regulatory framework and emergency preparedness, offer insights into the management of water resources in Chelan County, Washington. The dam's location, dimensions, storage capacity, and hazard potential make it a focal point for monitoring and ensuring the safety of nearby communities and the environment.
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 Asamera Cannon Mine Tailings Dam
Where does the data for Asamera Cannon Mine Tailings 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 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.
