Necedah Wildlife Refuge 30 dam
Necedah Wildlife Refuge 30
Necedah Wildlife Refuge 30 is a federal-owned structure located in Juneau, Wisconsin, and serves as a key component in managing the water resources of the Danielson Lateral. Completed in 1975, this earth dam stands at 15 feet high and has a length of 6000 feet, providing a storage capacity of 12,400 acre-feet. With a controlled spillway and a low hazard potential, the dam is deemed to be in fair condition and is inspected every 10 years to ensure its safety and functionality.
Despite its primary purpose being labeled as "Other," Necedah Wildlife Refuge 30 plays a crucial role in maintaining the ecological balance and water supply of the surrounding area. With a surface area of 1600 acres and a maximum discharge capacity of 800 cfs, this dam helps regulate water flow and supports the diverse wildlife habitats within the refuge. Additionally, the structure's risk assessment indicates a very high risk level, emphasizing the importance of effective risk management measures to protect both the dam and the surrounding environment.
As climate change continues to impact water resources, structures like Necedah Wildlife Refuge 30 become increasingly vital for ensuring water availability and flood control. With its strategic location and function, this dam exemplifies the intersection of water resource management and ecological conservation, making it a significant asset for both water resource and climate enthusiasts alike.

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 Necedah Wildlife Refuge 30
Where does the data for Necedah Wildlife Refuge 30 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.
