Arlington Subwatershed Sta 51+00 #6 dam
Arlington Subwatershed Sta 51+00 #6
Arlington Subwatershed Sta 51+00 #6 is a low hazard potential dam located in Woodbury County, Iowa, managed by the local government. Built in 1965 for fire protection, stock, and small fish pond purposes, this earth dam stands at a height of 29 feet with a length of 334 feet, providing a storage capacity of 50 acre-feet and covering a surface area of 2.4 acres. The dam serves the TR-West Fork Little Sioux River and is regulated by the Iowa Department of Natural Resources.
Despite being categorized as low risk, Arlington Subwatershed Sta 51+00 #6 has a moderate risk assessment of 3, indicating potential issues that need to be monitored and managed. The dam has not been rated for condition assessment, and there is no information available on emergency action plans or inundation maps. With no outlet gates or locks, the dam relies on an uncontrolled spillway for water discharge, suggesting limited control over water flow in case of overflow. Climate and water resource enthusiasts may find this structure interesting for its historical significance and its role in local water management practices.
Although Arlington Subwatershed Sta 51+00 #6 may not pose an immediate threat, ongoing monitoring and maintenance are essential to ensure its continued safety and functionality. With its primary purpose of flood risk reduction in mind, stakeholders and regulators should work together to prioritize the inspection and potential upgrades of this important infrastructure. Understanding the complexities of dam management and the potential impact of climate change on water resources is crucial for the long-term sustainability of structures like Arlington Subwatershed Sta 51+00 #6.
Dam data reference
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 Arlington Subwatershed Sta 51+00 #6
Where does the data for Arlington Subwatershed Sta 51+00 #6 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.
