Teller Lake No. 5 - West dam
Teller Lake No. 5 - West
Teller Lake No. 5 - West, also known as Hoffman Lake, Dexter Lake, and Davidson Lake, is a charming water resource located in Boulder, Colorado. Managed by the local government, this dam was completed in 1911 for the primary purpose of irrigation, with additional recreational opportunities available. The earth dam stands at a height of 9 feet, with a length of 1700 feet and a storage capacity of 235 acre-feet.
Situated on Dry Creek-TR, Teller Lake No. 5 - West offers a serene 35-acre surface area for visitors to enjoy. With a spillway type of uncontrolled and a low hazard potential, the dam has been deemed to be in satisfactory condition as of the last inspection in October 2014. Despite its age, the structure has a moderate risk assessment score of 3, indicating a need for ongoing monitoring and risk management measures to ensure its continued safety and functionality.
Climate and water resource enthusiasts will appreciate the historical significance and ecological value of Teller Lake No. 5 - West. With its picturesque surroundings and important role in irrigation, this dam serves as a reminder of the delicate balance between human development and environmental conservation. As a regulated and permitted structure, it stands as a testament to the careful stewardship of Colorado's water resources by the Department of Water Resources.

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.
Plan around the weather

About Teller Lake No. 5 - West
Where does the data for Teller Lake No. 5 - West 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.
