About this dam

Sd Noname 213

Sd Noname 213 is a privately owned dam located in Haakon, South Dakota, with a low hazard potential and a moderate risk assessment rating. Built in 1968, this earth dam stands at 14 feet high and spans 600 feet in length, providing a storage capacity of 110 acre-feet for the TR CHEYENNE river. Despite its age, the dam remains in a condition that has not been formally assessed.

Managed by the Natural Resources Conservation Service, Sd Noname 213 is regulated and inspected by the South Dakota Department of Environment and Natural Resources. While the dam's primary purpose is unspecified, its design includes an uncontrolled spillway and a maximum discharge capacity of 1250 cubic feet per second. With a state permit and regular inspections in place, the dam ensures ongoing safety and compliance with regulatory standards.

Though not federally owned or funded, Sd Noname 213 plays a crucial role in water resource management in the region. Situated in a county with a private owner, this dam serves as a vital infrastructure for flood control, water storage, and irrigation purposes. With its strategic location and functional design, Sd Noname 213 stands as a testament to the collaborative efforts of state agencies and private entities in ensuring sustainable water resource management 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 Sd Noname 213

Where does the data for Sd Noname 213 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.
