About this dam

Haskins Number 1

Haskins Number 1 is a private earth dam located in Fort Pierre, South Dakota, along Branch Willow Creek. Constructed in 1935 by the Natural Resources Conservation Service, this dam stands at a height of 17 feet and has a storage capacity of 120 acre-feet. With a significant hazard potential and a condition assessment of "Not Rated", Haskins Number 1 plays a crucial role in water resource management in the region.

Despite being regulated by the South Dakota Department of Environment and Natural Resources, Haskins Number 1 lacks certain critical information such as inspection dates, emergency action plans, and risk assessment details. The dam's maximum discharge capacity is recorded at 1560 cubic feet per second, emphasizing the need for regular maintenance and monitoring to ensure the safety of downstream communities and the surrounding ecosystem. Its location in Stanley County, near the city of Fort Pierre, highlights the importance of this structure in mitigating flood risks and supporting agricultural activities in the area.

As a key component in the local water infrastructure, Haskins Number 1 serves as a critical water management tool for the region. With its historical significance and essential role in regulating water flow along Branch Willow Creek, continued oversight and maintenance of this dam are essential for ensuring both water resource sustainability and climate resilience in South Dakota.

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 Haskins Number 1

Where does the data for Haskins Number 1 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.
