About this dam

Tate Dam

Tate Dam, situated in Todd, South Dakota, along Antelope Creek, was completed in 1986 and stands at a height of 14 feet. Owned privately, this earth dam boasts a storage capacity of 300 acre-feet and serves a primary purpose that is not specified. With a low hazard potential and a "Not Rated" condition assessment, Tate Dam is regulated by the South Dakota Department of Agriculture and Natural Resources, ensuring regular inspections, permitting, and enforcement measures are in place.

Despite its relatively modest size, Tate Dam plays a crucial role in managing water resources in the region, with a normal storage capacity of 79 acre-feet and a maximum discharge of 1535 cubic feet per second. The dam's location within the St. Paul District of the US Army Corps of Engineers adds an additional layer of oversight, although it is not operated by a federal agency. While details on the dam's spillway type and gates are unavailable, its overall design as an earth dam suggests a focus on cost-effective construction methods while providing essential flood control and water storage capabilities.

For water resource and climate enthusiasts, Tate Dam represents a vital piece of infrastructure in South Dakota's water management system. Its presence along Antelope Creek helps regulate water flow, reduce flood risks, and ensure a stable water supply for surrounding communities. With its low hazard potential and state-regulated status, Tate Dam stands as a testament to the importance of effective dam construction and maintenance in safeguarding against water-related emergencies and preserving valuable natural resources for future generations.

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 Tate Dam

Where does the data for Tate Dam 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.
