About this dam

Dowdy Lake

Dowdy Lake, located in Larimer County, Colorado, is a state-regulated water resource primarily used for recreation and as a fish and wildlife pond. The Earth dam, standing at 32 feet high and 850 feet long, was completed in 1962 and has a storage capacity of 1339 acre-feet. With a surface area of 83 acres, Dowdy Lake offers a picturesque setting for outdoor enthusiasts to enjoy various recreational activities.

Managed by the Colorado Department of Water Resources, Dowdy Lake has a spillway width of 15 feet and a maximum discharge capacity of 440 cubic feet per second. The dam's hazard potential is rated as significant, although its condition assessment was deemed satisfactory as of August 2019. The risk assessment for the dam is moderate, with emergency action plans in place to mitigate potential risks and ensure public safety in the event of an emergency.

For water resource and climate enthusiasts, Dowdy Lake serves as a valuable asset in the region, providing both recreational opportunities and important wildlife habitat. As a state-owned and regulated facility, Dowdy Lake exemplifies the importance of proper dam management and maintenance to ensure the safety and well-being of local communities and ecosystems. With its serene surroundings and diverse ecosystem, Dowdy Lake is a must-visit destination for those seeking to connect with nature and appreciate the beauty of Colorado's 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.

FAQ

About Dowdy Lake

Where does the data for Dowdy 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 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.
