Whitewater Reservoir Saddle Dam dam
Whitewater Reservoir Saddle Dam
Whitewater Reservoir Saddle Dam, also known as the North Dam, is a crucial water resource infrastructure located in St. Louis County, Minnesota. This earth dam, primarily designed for water supply purposes, stands at 31 feet high with a structural height of 36 feet and a length of 2160 feet. Completed in 1954, this dam has a storage capacity of 26,873 acre-feet, serving as a key component in managing the water supply in the area.
Managed by a public utility, Whitewater Reservoir Saddle Dam is regulated by the Minnesota Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and functionality. The dam is situated on the St. Louis River, contributing to its drainage area of 112 square miles. With a significant hazard potential and a condition assessment yet to be rated, regular inspections are conducted to monitor its safety and integrity.
Despite the lack of detailed data on spillway type and discharge capacity, Whitewater Reservoir Saddle Dam remains a critical infrastructure for water supply in the region. With its strategic location and storage capacity, this dam plays a vital role in managing water resources and ensuring a reliable supply for the surrounding communities, highlighting the importance of proper regulation and maintenance for sustainable water management in the area.

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 Whitewater Reservoir Saddle Dam
Where does the data for Whitewater Reservoir Saddle Dam 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.
