Alfred James Detention Dam dam
Alfred James Detention Dam
Alfred James Detention Dam, located in Garfield, Nebraska, serves a critical role in flood risk reduction along the TR-BEAN CREEK. Constructed in 1964 by the USDA NRCS, this private-owned earth dam stands at a height of 26 feet and spans 220 feet in length. With a storage capacity of 130 acre-feet and a normal storage of 58 acre-feet, the dam plays a significant role in managing water resources in the area.
Managed by the Nebraska Department of Natural Resources, Alfred James Detention Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. Despite being classified with a low hazard potential and fair condition assessment, the dam undergoes regular inspections every five years to monitor its performance. Its location in a rural setting underscores its importance in protecting the surrounding community from potential flooding events.
With its primary purpose being flood risk reduction, Alfred James Detention Dam also serves other functions in water resource management. Supported by the Natural Resources Conservation Service, the dam exemplifies the collaborative efforts between private owners and government agencies in safeguarding local communities against the impacts of extreme weather events and climate change.

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 Alfred James Detention Dam
Where does the data for Alfred James Detention 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.
