Aegon Dam dam
Aegon Dam
Aegon Dam, also known as Mc Leod Dam, is a privately owned recreational dam located in Cedar Rapids, Iowa. Built in 1997 by HALL AND HALL ENGINEERS, the dam stands at a height of 26 feet and spans 2660 feet across Prairie Creek. With a storage capacity of 124 acre-feet, the dam primarily serves recreational purposes and is a popular spot for water resource and climate enthusiasts in Linn County.
Despite its satisfactory condition assessment, Aegon Dam poses a high hazard potential due to its uncontrolled spillway type and moderate risk rating. The dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections, with the last assessment conducted in July 2020. With a drainage area of 0.12 square miles and a surface area of 6.6 acres, the dam plays a crucial role in managing water flow and ensuring the safety of the surrounding community.
As a key feature in the local landscape, Aegon Dam provides both recreational opportunities and essential water management functions. Its strategic location in Cedar Rapids, along with its significant storage capacity and high hazard potential, make it a focal point for water resource and climate enthusiasts interested in understanding the intersection of infrastructure, environment, and recreation in Iowa.

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.
Plan around the weather

About Aegon Dam
Where does the data for Aegon 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 High 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.
