Summary

Serving primarily for recreation, the dam stands at a height of 25 feet and has a hydraulic height of 20 feet. With a normal storage capacity of 70 acre-feet and a maximum discharge of 167 cubic feet per second, the dam covers a surface area of 18 acres and has a drainage area of 9 square miles. Despite its age, the dam's condition is deemed satisfactory, with a high hazard potential due to its structural height and location.

The Springville dam has undergone modifications in 1905 and 1997, with the last inspection conducted in July 2017. With a moderate risk assessment rating of 3, the dam is regulated by the Wisconsin Department of Natural Resources (WIDNR), with state permitting, inspection, and enforcement in place. The emergency action plan (EAP) for Springville has not been updated recently, but the dam meets safety guidelines. It is important for water resource and climate enthusiasts to monitor the condition of the Springville dam to ensure its continued safety and functionality for recreational purposes.

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.
