Sumner Twp 25 dam
Sumner Twp 25
Sumner Twp 25, also known as Mistakenly Rudlong Pond, is a privately owned structure located in Fillmore County, Minnesota. This dam on Kedron Brook was designed by NRCS with state regulation and permitting by MNDNR EWR. With a primary purpose of flood risk reduction, the earth dam stands at 24 feet high and spans a length of 260 feet, providing a storage capacity of 53 acre-feet.
Despite its low hazard potential and satisfactory condition assessment, Sumner Twp 25 has a normal storage capacity of 4 acre-feet and covers a surface area of 1 acre with a drainage area of 0.22 square miles. The dam's maximum discharge capacity is 422 cubic feet per second, showcasing its ability to manage water flow efficiently. With state inspection, enforcement, and regulation in place, this structure plays a crucial role in mitigating flood risks in the region.
Situated in the city of Whalan, Sumner Twp 25 is a vital component of the local water resource infrastructure. With its association with the St. Paul District of the USACE and a history of satisfactory condition assessments, this dam serves as a key asset in flood risk reduction efforts along Kedron Brook. The data highlights the importance of proper maintenance and regulatory oversight to ensure the continued effectiveness of this essential water management structure for the community.
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 Sumner Twp 25
Where does the data for Sumner Twp 25 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.
