Hanna Ranch Supernatant dam
Hanna Ranch Supernatant
Hanna Ranch Supernatant is a public utility located in Pueblo, Colorado along the Fountain Creek-TR river stream. Completed in 1996, this Earth dam stands at a height of 35 feet and has a structural height of 71 feet, providing a maximum storage capacity of 507 acre-feet. The dam's primary purpose is listed as "Other," with a spillway type of "Uncontrolled" and a hazard potential rated as "Low."
Despite its low hazard potential, Hanna Ranch Supernatant plays a crucial role in managing water resources in the region, with a normal storage capacity of 375 acre-feet and a maximum discharge of 700 cubic feet per second. The dam's risk assessment is classified as moderate, indicating a level 3 risk. While the condition assessment is marked as "Not Rated," the dam is state-regulated, inspected, and permitted, ensuring its compliance with safety and environmental regulations.
With its strategic location and impact on water management, Hanna Ranch Supernatant is a significant asset in the region's water infrastructure. As a key component in the overall water resource management system, this Earth dam provides essential storage capacity and flood protection along the Fountain Creek-TR, highlighting the importance of sustainable water resource management in the face of climate challenges and changing environmental conditions.

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 Hanna Ranch Supernatant
Where does the data for Hanna Ranch Supernatant 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.
