About this dam

Haxton Pond

Haxton Pond, located in Rollingstone, Minnesota, is a privately owned earth dam designed by the USDA NRCS in 1978 for the primary purpose of flood risk reduction. This significant dam stands at 24 feet high and stretches 430 feet in length, with a storage capacity of 43 acre-feet. It is regulated and permitted by the Minnesota Department of Natural Resources and undergoes regular inspections to ensure its satisfactory condition.

The dam on Haxton Pond poses a moderate risk level and is equipped with uncontrolled spillways and outlet gates. Despite its age, the structure has been deemed to meet guidelines and is considered to have satisfactory conditions as of the last assessment in 2015. The dam is associated with Speltz Creek-TR and has a drainage area of 0.6 square miles, with a maximum discharge capacity of 400 cubic feet per second. With its historical significance in flood risk reduction and environmental management, Haxton Pond remains a key feature in the St. Paul District's water resource infrastructure.

As an essential component in the management of water resources and flood control in Winona County, Minnesota, Haxton Pond plays a crucial role in mitigating potential hazards and protecting downstream areas from flooding. With its designed buttress core and uncontrolled spillways, the dam continues to function effectively in reducing flood risk and safeguarding the surrounding community. As climate change impacts water systems, the proper regulation and maintenance of structures like Haxton Pond are vital in preserving the ecological balance and ensuring the safety of residents in the region.

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.

FAQ

About Haxton Pond

Where does the data for Haxton Pond 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.
