About this dam

Charles Sargent Dam

Charles Sargent Dam, located in Oakville, Michigan, is a vital local government-owned structure on the Hewens Drain river. Completed in 1972, this earth dam stands at a height of 14 feet and serves primarily for recreational purposes, offering a serene environment for water resource and climate enthusiasts to enjoy. With a maximum storage capacity of 84 acre-feet and a normal storage of 55 acre-feet, the dam covers a surface area of 10 acres and has a drainage area of 0.4 square miles.

Despite its moderate risk assessment rating of 3, the dam has a low hazard potential and has been deemed to be in satisfactory condition during its last inspection in October 2018. With a spillway width of 9 feet and an uncontrolled spillway type, Charles Sargent Dam ensures the safe release of excess water to prevent flooding and maintain the structural integrity of the dam. Its location in Washtenaw County, Michigan, makes it a key feature of the local landscape, providing both practical and recreational benefits to the community.

Overall, Charles Sargent Dam is an important water resource structure in Michigan, contributing to the region's water management efforts and offering a peaceful recreational space for visitors. With its low hazard potential and satisfactory condition, the dam continues to play a crucial role in maintaining water levels and ensuring the safety of surrounding areas. For water resource and climate enthusiasts, this dam represents a harmonious blend of functionality and natural beauty, making it a must-visit destination for those interested in sustainable water management practices and environmental conservation.

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.
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.
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.

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, environmental 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.

FAQ

About Charles Sargent Dam

Where does the data for Charles Sargent Dam come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Low hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
