B-2 dam
B-2
B-2, located in Moffat County, Colorado, serves as a vital infrastructure for fire protection, stock watering, and small fish pond purposes. This Earth-type dam, completed in 1960, stands at a height of 25 feet and spans 450 feet in length, holding a storage capacity of 65 acre-feet. The dam is situated on the Little Snake River and is regulated by the state's Department of Water Resources, ensuring proper permitting, inspection, and enforcement measures are in place.
Despite being categorized as having a low hazard potential, B-2 poses moderate risk, prompting the need for ongoing risk management measures. The dam's condition assessment remains unrated, with the last inspection conducted in November 2019, highlighting the importance of regular monitoring and maintenance to ensure its structural integrity and safety. While the dam currently meets guidelines for emergency action plans (EAP), further updates and preparations may be necessary to enhance its resilience in the face of potential disasters.
As a key component of water resource management in the region, B-2 serves as a critical asset for both agricultural and environmental purposes. Its strategic location and multi-faceted functionalities underscore the significance of proper regulation and maintenance to safeguard water resources and mitigate potential risks associated with its operation. Enthusiasts of water resources and climate change will find B-2 to be a compelling case study in the intersection of infrastructure, sustainability, and resilience in the face of evolving environmental challenges.
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 B-2
Where does the data for B-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 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.
