Summary

Completed in 1936, this dam on Spring Brook serves primarily for recreational purposes, with a height of 10 feet and a length of 136 feet. Its maximum storage capacity is 175 acre-feet, with a normal storage level of 70 acre-feet and a surface area of 32 acres.

Despite being classified as low hazard potential with satisfactory condition assessment, Faust is under the regulatory jurisdiction of the Wisconsin Department of Natural Resources (WIDNR). The dam has a controlled spillway type with a maximum discharge capacity of 1450 cubic feet per second. The risk assessment for Faust indicates a very high risk level, but the specific risk management measures and guidelines for emergency action plans are not readily available in the data.

Overall, Faust presents an interesting case study for water resource and climate enthusiasts, highlighting the importance of proper dam maintenance, risk assessment, and emergency preparedness in ensuring the safety and functionality of such structures. The dam's historical significance, recreational value, and regulatory oversight by state agencies like WIDNR offer valuable insights into the intersection of water management, infrastructure development, and environmental protection in Wisconsin.

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.
