Sueno dam
Sueno
Sueno, also known as South Valley, is a private irrigation structure located in Stonewall, Colorado, along the Purgatoire River. Completed in 1989, this earth dam stands at a height of 20 feet with a length of 1091 feet, providing a storage capacity of 162 acre-feet for irrigation purposes. The dam's spillway type is uncontrolled, with a width of 27 feet, and it has a low hazard potential with a satisfactory condition assessment as of June 2016.
With its primary purpose being irrigation, Sueno also serves as a Fish and Wildlife Pond in addition to supporting agricultural activities in the region. The dam's maximum discharge capability is 3200 cubic feet per second, ensuring efficient water management for the surrounding area. Despite being privately owned, the state of Colorado regulates and inspects the structure regularly to ensure its continued safety and functionality, highlighting the commitment to water resource management and climate resilience in the region.
Located in Las Animas County, Sueno plays a crucial role in water storage and distribution, contributing to the overall water security of the area. With its stone core and uncontrolled spillway, this structure showcases a blend of traditional dam construction methods with modern safety protocols. As climate change impacts water resources, structures like Sueno become essential in maintaining a sustainable balance between agricultural needs and environmental conservation along the Purgatoire River in Colorado.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Sueno
Where does the data for Sueno 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.
