Arkno Name 350 dam
Arkno Name 350
Arkno Name 350 is a privately owned earth dam located in Washington County, Arkansas, along the Hickory Creek-TR river. Built in 1964 for recreational purposes, this dam has a hydraulic height of 12 feet and a structural height of 14 feet, with a length of 300 feet. With a maximum storage capacity of 56 acre-feet and a normal storage capacity of 24 acre-feet, Arkno Name 350 serves as a low-hazard structure with a condition assessment of "Not Rated."
Despite being privately owned, Arkno Name 350 is not regulated or inspected by state agencies, and does not require permitting or enforcement. The dam has not been modified in recent years and lacks certain safety features such as spillways or outlet gates. The risk assessment and management measures for this dam are currently unknown, and emergency action plans and inundation maps have not been prepared.
Although Arkno Name 350 may not have the same level of oversight as some publicly owned dams, its low hazard potential indicates a lower risk for potential failures. However, the lack of recent inspections and safety features raises concerns about the structure's overall safety and resilience in the face of changing climate conditions and increasing water resource demands. Water resource and climate enthusiasts should keep an eye on developments related to Arkno Name 350 to ensure the continued safety and sustainability of this recreational dam.

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 Arkno Name 350
Where does the data for Arkno Name 350 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.
