About this dam

Concannon Marsh Dam

Concannon Marsh Dam, also known as Ksnoname 712, is a privately owned structure located in Burdett, Kansas. Built in 1952 by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 19 feet and a length of 975 feet, the dam has a storage capacity of 150 acre-feet and covers a surface area of 15.21 acres. Despite being unregulated by the state, the dam has a low hazard potential and has not been rated for its condition assessment.

Situated on the Pawnee River-TR, Concannon Marsh Dam is part of the Kansas City District and falls within the jurisdiction of Finney County, Kansas. The dam features an uncontrolled spillway with a width of 350 feet and has no outlet gates or associated locks. While it has not been regularly inspected since 2003, the dam is considered to have moderate risk potential. Despite its lack of state regulation and inspection, the dam continues to serve its intended purposes effectively, providing essential water resources for its owners and the surrounding area.

As a vital structure for fire protection and water management in the region, Concannon Marsh Dam remains an important asset despite its low hazard potential and moderate risk assessment. With its historical significance dating back to 1952, the dam serves as a testament to the enduring importance of water resource management in the face of changing climate patterns. The dam's presence highlights the need for continued monitoring and maintenance to ensure its reliability and safety for the community it serves.

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 Concannon Marsh Dam

Where does the data for Concannon Marsh 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.
