Sherburne Nat'l Pool 7b dam
Sherburne Nat'l Pool 7b
Sherburne National Pool 7b, located in Elk River, Minnesota, is a federal-owned earth dam constructed in 1979 with a primary purpose of "Other." The dam stands at a height of 7 feet and stretches 2600 feet in length, with a maximum storage capacity of 1498 acre-feet and a normal storage capacity of 856 acre-feet. Its hazard potential is rated as "Low" and its condition assessment is listed as "Not Rated."
Managed by the St. Paul District of the US Army Corps of Engineers, Sherburne National Pool 7b plays a crucial role in regulating the flow of the St. Francis River-TR. Despite its low hazard potential, the dam has not been inspected recently, with the last recorded inspection frequency being 8 years. The emergency action plan (EAP) status, risk assessment, and risk management measures for the dam are currently listed as unknown, indicating a potential need for further evaluation and preparedness.
For water resource and climate enthusiasts, Sherburne National Pool 7b serves as a significant infrastructure in Sherburne County, Minnesota, contributing to water storage and flow regulation in the region. The dam's location and design are essential factors in managing water resources and ensuring the safety and security of the surrounding area. With its low hazard potential and unknown condition assessment, there is a potential opportunity for stakeholders to prioritize inspection, risk assessment, and emergency preparedness efforts for this vital water management structure.

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 Sherburne Nat'l Pool 7b
Where does the data for Sherburne Nat'l Pool 7b 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.
