Lazy O Reservoir No 2 dam
Lazy O Reservoir No 2
Lazy O Reservoir No 2, also known as Lazy O Ranch Reservoir, is a private water resource located in Snowmass, Colorado. Constructed in 1990 by ALPINE ENGINEERING and SCHMUESER, GORDON, MEYER INC, this Earth type dam stands at 18 feet in height and has a maximum storage capacity of 31 acre-feet. The primary purpose of this reservoir is for fish and wildlife management, as well as water supply.
Situated along the Capital Creek, Lazy O Reservoir No 2 covers a surface area of 3 acres and has a significant hazard potential with a fair condition assessment. The dam has been modified in 2001 and 2009 for hydraulic purposes, with an uncontrolled spillway type and one outlet valve. Inspected biennially, the reservoir has an associated risk assessment rating of moderate (3) and is regulated by the Colorado Department of Water Resources, ensuring its compliance with state standards.
Overall, Lazy O Reservoir No 2 serves as a vital resource for fish and wildlife conservation in the Pitkin County area, while also providing water supply benefits. With its picturesque location and important role in the local ecosystem, this reservoir stands as a testament to responsible water management practices and the preservation of natural habitats in the region.
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 Lazy O Reservoir No 2
Where does the data for Lazy O Reservoir No 2 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.
