Summary
The dam stands at a height of 24 feet with a hydraulic height of 21 feet and a length of 137 feet, impounding a reservoir with a normal storage capacity of 380 acre-feet. The dam overlooks the picturesque Elk Creek, providing a serene setting for outdoor enthusiasts and nature lovers to enjoy a variety of recreational activities.
Despite being classified with a low hazard potential, Elk Creek Dam has undergone modifications in 1934, 1953, 1988, and 1998. A recent inspection in May 2020 rated the dam's condition as fair, with a very high risk assessment score of 1. While the dam is under state regulation by the Wisconsin Department of Natural Resources, it has not been associated with any federal agencies for funding, design, construction, or operation. With its rich history and contribution to the local water supply and recreation, Elk Creek Dam remains a significant landmark in the region.
As a gravity dam nestled in the Detroit District, Elk Creek Dam holds a special place in the hearts of water resource and climate enthusiasts. Its tranquil reservoir, covering 46 acres and serving a drainage area of 80 square miles, provides a valuable habitat for wildlife and a serene backdrop for outdoor activities. With its controlled spillway and history dating back over a century, Elk Creek Dam continues to be a vital part of the local landscape, offering both practical water supply benefits and recreational opportunities for visitors to enjoy.

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.
