Summary

Constructed in 1968 by the USDA NRCS, this local government-owned dam serves primarily for recreational purposes, offering a serene environment for visitors to enjoy. The dam stands at a height of 15 feet, with a hydraulic height of 11 feet, and a length of 2437 feet, creating a surface area of 31 acres and a drainage area of 1.84 square miles.

Managed by the Wisconsin Department of Natural Resources, La Blonde has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in October 2018. The dam has a storage capacity of 365 acre-feet, with a maximum discharge rate of 451 cubic feet per second. In case of emergencies, the dam has a controlled spillway type and is subject to regular inspections every 10 years. Despite being a relatively low-risk structure, La Blonde is situated in a high-risk area, emphasizing the importance of ongoing risk management measures.

With its picturesque location on Kaminski Creek and its reputation for offering a peaceful retreat for outdoor enthusiasts, La Blonde stands as a testament to the harmonious coexistence between water resource management and recreational enjoyment. Its rich history and continued maintenance by the Natural Resources Conservation Service make it a valuable asset for both the local community and visitors seeking a tranquil escape in the heart of Wisconsin's natural beauty.

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. 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

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, 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.
