Canon No. 4 dam
Canon No. 4
Canon No. 4, located in Albany County, Wyoming, is a privately owned Earth dam constructed in 1959 for irrigation purposes on Timber Canon Creek. With a height of 34 feet and a length of 370 feet, this dam provides a storage capacity of 77 acre-feet, with a normal storage level of 51 acre-feet. The dam's spillway type is uncontrolled, with a width of 24 feet, and it has an outlet gate valve for water release.
Despite being classified as having a low hazard potential and fair condition assessment, Canon No. 4 is subject to regular inspections every five years, with the last assessment conducted in June 2020. The risk assessment for this dam is moderate (3), indicating a need for ongoing monitoring and potential risk management measures in place. With its strategic location in the city of Torrington and its vital role in irrigation, Canon No. 4 serves as a crucial water resource structure in the region, regulated by the Wyoming State Engineer's Office.
Water resource and climate enthusiasts will be intrigued by Canon No. 4's unique characteristics, including its stone core and soil foundation, as well as its moderate risk assessment level. With its historical significance dating back to the late 1950s, this Earth dam continues to play a vital role in water storage and distribution for agricultural purposes in Wyoming. As climate change impacts water resources, understanding the condition and maintenance of structures like Canon No. 4 is essential for ensuring the sustainability and resilience of water infrastructure in the face of changing environmental conditions.
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 Canon No. 4
Where does the data for Canon No. 4 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.
