Yellow Moccasin Dam dam
Yellow Moccasin Dam
Yellow Moccasin Dam, located in Arlington, Nebraska, is a private earth dam primarily used for recreation purposes. Completed in 2000, the dam stands at a height of 20 feet and has a length of 1325 feet, creating a reservoir with a normal storage capacity of 59.6 acre-feet. The dam is situated on the TR-Brown Creek and is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
With a low hazard potential and a condition assessment that is currently not rated, Yellow Moccasin Dam offers a picturesque setting for water resource and climate enthusiasts to explore. The dam's location in Washington County, Nebraska, provides opportunities for recreational activities such as fishing, boating, and wildlife observation. Although the dam has not been modified in recent years, regular inspections are conducted to monitor its structural integrity and ensure the safety of the surrounding community.
As a key feature in the local landscape, Yellow Moccasin Dam serves as a vital water resource and recreational asset for the area. Its tranquil waters and scenic surroundings make it a popular destination for outdoor enthusiasts seeking to connect with nature and enjoy the benefits of sustainable water management practices. With proper oversight and maintenance, Yellow Moccasin Dam continues to be a valuable asset for both the community and the environment.

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 Yellow Moccasin Dam
Where does the data for Yellow Moccasin 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.
