Summary
10, also known as Abbot Ranch Flowage, is a gravity dam located in Clark County, Wisconsin. Completed in 1967, this dam serves a primary purpose of "Other" and has a normal storage capacity of 30 acre-feet, with a maximum storage capacity of 50 acre-feet. The dam stands at a height of 10 feet and has a structural height of 10 feet, with a length of 2600 feet. Its associated drainage area covers 3 square miles, and the maximum discharge rate is recorded at 580 cubic feet per second.
This dam is regulated by the Wisconsin Department of Natural Resources (WIDNR) and is subject to state permitting, inspection, and enforcement. The last inspection in October 2017 rated the dam's condition as "Fair" with a low hazard potential. Despite its relatively low hazard potential, a risk assessment has classified the dam's risk level as "Very High (1)", indicating the importance of ongoing monitoring and maintenance to ensure its safety and stability. With its strategic location along Hay Creek and Creek 14-12, Clark County No. 10 plays a crucial role in water resource management in the region.
Enthusiasts of water resources and climate will find Clark County No. 10 to be an intriguing infrastructure project that highlights the intersection of human engineering and environmental stewardship. As a key component of the local government's water management system, this dam showcases the delicate balance between harnessing water resources for human use and protecting the surrounding ecosystem. With its historical significance and ongoing regulatory oversight, Clark County No. 10 serves as a valuable case study for understanding the complexities of managing water resources in a dynamic and ever-changing climate.

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.
