Wd Crockett dam
Wd Crockett
Wd Crockett is a privately owned dam located in Perkins, South Dakota, along the TR-GRAND RIVER. Completed in 1949, this earth dam stands at a height of 19 feet and has a storage capacity of 69 acre-feet, with a maximum discharge of 2560 cubic feet per second. Despite being of low hazard potential, the dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources, ensuring its safety and compliance with state regulations.
The dam's primary purpose and associated structures are not specified, but its condition is reported as "Not Rated," with no recent inspection date provided. The surrounding area does not have inundation maps prepared or an emergency action plan in place, raising questions about preparedness in case of a dam failure. With the dam being privately owned, it is crucial for the owner to prioritize safety measures and compliance with regulatory agencies to mitigate potential risks and ensure the protection of water resources and the environment.
In terms of federal involvement, Wd Crockett does not have any funding, oversight, or other support from federal agencies, as it falls solely under the jurisdiction of the state of South Dakota. With its location in a rural area and limited information available on its management and maintenance, enthusiasts of water resources and climate may find Wd Crockett to be an intriguing case study in the complexities of dam ownership and regulation at the state level.

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 Wd Crockett
Where does the data for Wd Crockett 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.
