Little Yellow 10 dam
Little Yellow 10
Little Yellow 10 is a gravity dam located in Necedah, Wisconsin, along the East Branch of Little Yellow River. Built in 1936, this Federal-owned structure serves primarily for irrigation purposes, with additional benefits for recreation and water supply. The dam has a height of 7 feet and a storage capacity of 150 acre-feet, providing essential water resources for the surrounding area.
Despite its low hazard potential, Little Yellow 10 is classified with a very high risk assessment rating of 1, indicating the importance of proper risk management measures. With a drainage area of 8.2 square miles and a maximum discharge capacity of 385 cubic feet per second, this dam plays a crucial role in managing water flow and ensuring water availability for irrigation and other purposes in the region. The dam's condition assessment is currently listed as "Not Rated," highlighting the need for ongoing monitoring and maintenance to ensure its continued safety and functionality.
Overall, Little Yellow 10 serves as a vital infrastructure for water resource management in Juneau County, Wisconsin. With its historical significance and important role in irrigation and water supply, this gravity dam stands as a reminder of the critical link between water resources and climate resilience in the region. Ongoing risk assessment and management efforts will be crucial to safeguarding the dam's integrity and ensuring its continued contribution to the local community's water needs.

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 Little Yellow 10
Where does the data for Little Yellow 10 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.
