About this dam

Mc Call Subwatershed 1-2182

Mc Call Subwatershed 1-2182, located in Monona, Iowa, is a crucial water resource managed by the local government and regulated by the Iowa Department of Natural Resources. This subwatershed plays a vital role in fire protection, stock maintenance, and small fish pond purposes, while also contributing to flood risk reduction in the region. The primary dam in this subwatershed, completed in 1965, is an earth dam with a height of 27 feet and a storage capacity of 16 acre-feet.

Despite its low hazard potential, Mc Call Subwatershed 1-2182 faces a moderate risk level, highlighting the importance of ongoing monitoring and management measures. The dam's condition is currently not rated, emphasizing the need for regular inspections to ensure its structural integrity and safety. With a drainage area of 0.23 square miles and a surface area of 2 acres, this subwatershed plays a critical role in managing water flow and mitigating potential risks for the surrounding community.

As water resource and climate enthusiasts, understanding the significance of Mc Call Subwatershed 1-2182 in the Little Sioux River system is essential for promoting sustainable water management practices and enhancing resilience to climate change impacts in the region. This subwatershed serves as a valuable asset for the community, and efforts to maintain its functionality and safety will be crucial for safeguarding both human and environmental well-being in the long run.

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 Mc Call Subwatershed 1-2182

Where does the data for Mc Call Subwatershed 1-2182 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.
