40th Street Dentention Basin dam
40th Street Dentention Basin
The 40th Street Detention Basin in Pueblo, Colorado, designed by CH2MHILL, serves as a crucial flood risk reduction infrastructure in the area. Completed in 1998, this earth dam stands at a height of 21 feet and has a hydraulic height of 19 feet, with a length of 961 feet and a storage capacity of 82 acre-feet. Situated on an unnamed tributary of the Fountain-OS River, this state-regulated basin plays a significant role in managing stormwater and reducing the risk of flooding in the region.
With a satisfactory condition assessment and a significant hazard potential, the 40th Street Detention Basin is equipped with an uncontrolled spillway and has a maximum discharge capacity of 1189 cubic feet per second. The basin covers a surface area of 6 acres and holds a normal storage volume of 77 acre-feet. The dam's associated structures include stone core types and soil foundations, emphasizing its reliability in flood risk mitigation. Regular inspections and a moderate risk assessment ensure the basin's effectiveness in addressing potential emergencies and maintaining public safety.
The 40th Street Detention Basin represents a critical piece of infrastructure in the flood management system of Pueblo, Colorado. With its strategic location and state-of-the-art design, this basin not only provides flood risk reduction but also contributes to the overall resilience of the community in the face of changing climate conditions. As water resource and climate enthusiasts, understanding and appreciating the significance of structures like the 40th Street Detention Basin is essential in safeguarding our communities against the impacts of extreme weather events and ensuring sustainable water management practices for the future.
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 40th Street Dentention Basin
Where does the data for 40th Street Dentention Basin 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 Significant 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.
