Florence South Res. No. 2 dam
Florence South Res. No. 2
Florence South Reservoir No. 2, also known as South Cell, is a vital water supply structure located in Fremont, Colorado. This local government-owned reservoir is regulated by the state's Department of Water Resources, ensuring proper permitting, inspection, and enforcement. The dam, primarily designed for water supply, is an earth type structure with a height of 39 feet and a length of 300 feet. With a storage capacity of 246 acre-feet, it serves the purpose of storing water from the First Alkali Creek-OS for the surrounding area.
Despite its satisfactory condition assessment, Florence South Reservoir No. 2 poses a high hazard potential, prompting regular inspections and risk assessments. The spillway, categorized as uncontrolled, has a width of 5 feet to manage excess discharge. In the event of an emergency, the reservoir is equipped with uncontrolled outlet gates for water release. While the risk level is moderate, measures for risk management and emergency action plans are essential components that are continually evaluated to ensure the safety and functionality of the reservoir.
With its key role in water supply and management in the region, Florence South Reservoir No. 2 stands as a critical infrastructure for water resource and climate enthusiasts. As a part of the broader network of water structures, this reservoir contributes to the overall water security and resilience of the area. It serves as a testament to the importance of proper regulation, maintenance, and risk assessment in safeguarding our water resources for the future.
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 Florence South Res. No. 2
Where does the data for Florence South Res. No. 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 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.
