About this dam

Swanson Lake Dam

Swanson Lake Dam, located in Buchanan, Missouri, was completed in 1920 and serves as a crucial water resource for the area. The dam, primarily used for purposes other than flood control or irrigation, stands at a height of 25 feet and has a maximum storage capacity of 67 acre-feet. It is classified as an Earth dam with a Buttress core type, contributing to its low hazard potential rating.

Situated on TR-PIGEON CREEK, Swanson Lake Dam is owned and operated by a private entity, making it exempt from state regulation and oversight. Despite its age, the dam's condition assessment is currently listed as "Not Rated", highlighting the need for further inspection and maintenance to ensure its long-term stability and safety. With a surface area of 5 acres and a drainage area of 35 acres, the dam plays a vital role in water management and conservation efforts in the region.

As a key feature in the Rock Island District, Swanson Lake Dam serves as a testament to early 20th-century engineering and continues to provide essential water storage and management capabilities for the surrounding community. With its historical significance and ongoing importance in water resource management, Swanson Lake Dam represents a blend of past expertise and modern-day necessity in addressing the challenges of climate change and water security.

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 Swanson Lake Dam

Where does the data for Swanson Lake 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.
