Mountain Supply # 1 dam
Mountain Supply # 1
Mountain Supply # 1, also known as Round Butte, is a vital water resource structure located in Larimer, Colorado. This dam, completed in 1904, serves the primary purpose of flood risk reduction along the Sand Creek. With a height of 35 feet and a storage capacity of 1,186 acre-feet, it plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events.
Although classified as low hazard potential, Mountain Supply # 1 currently has an unsatisfactory condition assessment as of June 2015. Despite this, the dam is regulated and inspected by the Colorado Department of Water Resources, ensuring that necessary enforcement and permitting measures are in place to maintain its structural integrity and safety. With a risk assessment rating of High (2), it is clear that ongoing risk management measures will be crucial to mitigate any potential threats and ensure the continued protection of the local community and environment.
Overall, Mountain Supply # 1 stands as a testament to the importance of effective water resource management and climate resilience in the face of changing environmental conditions. As a key component of the flood risk reduction infrastructure in the area, this dam serves as a vital lifeline for the community of Wellington and beyond, highlighting the critical role that such structures play in safeguarding against natural disasters and ensuring the sustainable use of water resources for future generations.
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 Mountain Supply # 1
Where does the data for Mountain Supply # 1 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.
