About this dam

Shackelford Dam

Shackelford Dam, located in Hitchcock, Nebraska, is a privately owned structure built in 1960 on the TR-Frenchman River for purposes of fire protection, stock, and as a small fish pond. The dam, primarily constructed of earth with buttress and stone core types, stands at a height of 16.6 feet and spans a length of 350 feet. With a storage capacity of 61.3 acre-feet, the dam serves a drainage area of 6.9 square miles and has a normal storage level of 28.1 acre-feet.

Managed by the Nebraska Department of Natural Resources, Shackelford Dam has a low hazard potential and is deemed to be in satisfactory condition following its last inspection in June 2011. The dam's emergency action plan status and risk assessment information are currently unavailable. Despite its minimal hazard potential, the dam's function as a vital resource for fire protection and livestock support highlights its importance within the local ecosystem.

Situated within Congressional District 03 of Nebraska, Shackelford Dam plays a crucial role in water resource management and climate resilience in the region. With its ability to store water for various purposes, the dam serves as a valuable asset for the community while also contributing to the environmental sustainability of the area. As enthusiasts of water resources and climate change, monitoring the condition and functionality of structures like Shackelford Dam is essential for ensuring the continued availability and conservation of water resources in the face of a changing climate.

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 Shackelford Dam

Where does the data for Shackelford 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.
