Pool One A dam
Pool One A
Pool One A is a federally-owned water resource located in Saginaw, Michigan, along Ferguson Bayou Offstream. The dam, completed in 1958, is primarily used for purposes other than flood control or water supply, with a low hazard potential and a moderate risk assessment. Despite being not rated for condition assessment, the dam stands at a height of 13 feet and spans a length of 11,220 feet, with a maximum storage capacity of 750 acre-feet and a normal storage capacity of 576 acre-feet.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), Pool One A is regulated, permitted, inspected, and enforced by state authorities. The dam features an uncontrolled spillway with a width of 200 feet and has not undergone significant modifications since its construction. While the dam has not been rated for its emergency action plan or inundation maps, the risk management measures are deemed effective for the moderate risk level associated with the structure.
With a historical significance dating back to over six decades, Pool One A serves as a vital component of the water resource infrastructure in Saginaw, Michigan. While the dam's condition assessment remains pending, its operations continue to support the surrounding ecosystem and communities with controlled water storage and discharge capabilities. As water resource and climate enthusiasts, the data surrounding Pool One A provides valuable insights into the management and maintenance of critical infrastructure for sustainable water resource utilization and environmental protection.
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 Pool One A
Where does the data for Pool One A 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.
