Rowan Dam (2-34-18w) dam
Rowan Dam (2-34-18w)
Rowan Dam (2-34-18w) is a privately owned irrigation structure located in Keya Paha, Nebraska, along the TR-KEYA PAHA RIVER. Completed in 1977, this earth dam stands at a height of 37 feet and spans 536 feet in length, with a storage capacity of 194 acre-feet. Despite its relatively low hazard potential, the dam's condition assessment is rated as poor, highlighting the need for ongoing maintenance and potential upgrades to ensure its long-term safety and functionality.
Managed by the Nebraska Department of Natural Resources, Rowan Dam plays a crucial role in providing irrigation water for the surrounding area. With a normal storage capacity of 177 acre-feet and a maximum discharge of 112 cubic feet per second, the dam helps support agricultural activities in the region. However, its condition assessment and hazard potential underscore the importance of regular inspections and maintenance to mitigate any potential risks to downstream communities and infrastructure.
Located within Congressional District 03, Nebraska, Rowan Dam is subject to state regulations and inspections to ensure compliance with safety standards. The dam's status as a privately owned structure with a low hazard potential emphasizes the need for continued monitoring and upkeep to safeguard both the local water resources and the surrounding environment. As water resource and climate enthusiasts, understanding the importance of maintaining and improving infrastructure like Rowan Dam is key to ensuring sustainable water management practices for future generations.

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 Rowan Dam (2-34-18w)
Where does the data for Rowan Dam (2-34-18w) 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.
