Summary
Completed in 1935, this gravity dam primarily serves the purpose of irrigation, with additional benefits for recreation and water supply. With a height of 9 feet and a hydraulic height of 7 feet, the dam has a storage capacity of 130 acre-feet and a normal storage level of 70 acre-feet.
The dam, situated on the West Branch Little Yellow River, has a low hazard potential and a very high risk assessment rating of 1. While its condition is currently not rated, the dam has undergone inspections every 10 years, with the last one conducted in July 2008. Managed by the Wisconsin Department of Natural Resources (WIDNR), Little Yellow 25 is equipped with a controlled spillway and has a maximum discharge capacity of 1,259 cubic feet per second.
Overall, Little Yellow 25 plays a crucial role in the local water resource management, providing essential irrigation water while also offering recreational opportunities and ensuring a stable water supply. As a key infrastructure in the area, its maintenance and regulatory oversight by the state agencies are essential to ensure its continued safe operation and compliance with environmental standards.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
