About this dam

Alexander Lake

Nestled in the picturesque city of Cedaredge, Colorado, Alexander Lake, also known as Reservoir #8, stands as a vital water resource for irrigation and recreation. This private-owned reservoir, completed in 1886, spans a surface area of 24 acres and holds a maximum storage capacity of 303 acre-feet. Surrounded by the serene Ward Creek and situated within the Delta County, Alexander Lake serves as a lifeline for agricultural activities in the region.

With its earth dam structure standing at a height of 11 feet and a length of 138 feet, Alexander Lake boasts a low hazard potential and fair condition assessment. Despite its modest size, the reservoir plays a crucial role in water management and supports a variety of recreational activities for locals and visitors alike. The absence of a spillway is compensated by slide and uncontrolled outlet gates, ensuring the steady flow of water for irrigation purposes.

Managed and regulated by the Colorado Department of Water Resources, Alexander Lake showcases a harmonious blend of functionality and natural beauty. Its historical significance and practical utility make it a hidden gem for water resource and climate enthusiasts seeking to explore the intersection of human intervention and environmental sustainability in the heart of Colorado's scenic landscape.

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.

FAQ

About Alexander Lake

Where does the data for Alexander Lake 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.

Premium feature
