Quincy dam
Quincy
Quincy, a local government-owned dam located in Aurora, Colorado, plays a vital role in water supply and recreation in the area. Built in 1974, this earth dam stands at a height of 70 feet and has a maximum storage capacity of 4560 acre-feet. With a surface area of 155 acres and a drainage area of 4 square miles, Quincy Dam helps regulate the flow of the West Toll Gate Creek and has a maximum discharge capacity of 27000 cubic feet per second.
Despite its age, Quincy Dam maintains a satisfactory condition assessment and is inspected regularly to ensure its structural integrity. With a high hazard potential due to its location and purpose, Quincy Dam is deemed to have a moderate risk level (3). The dam features an uncontrolled spillway and stands at a structural height of 73 feet, providing essential water supply and recreational opportunities while also posing potential risks that necessitate thorough risk management measures.
In the event of an emergency, the dam's Emergency Action Plan (EAP) is crucial for ensuring quick and effective responses. While specifics regarding the EAP's preparation and compliance with guidelines are not detailed in the data, the dam's last inspection in September 2020 deemed its condition as satisfactory. Quincy Dam serves as a critical infrastructure for the community, highlighting the importance of responsible management and maintenance to safeguard against potential risks and ensure the continued availability of water resources and recreational amenities for residents in the region.
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 Quincy
Where does the data for Quincy 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 High 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.
