Maxon Reservoir Dam dam
Maxon Reservoir Dam
Maxon Reservoir Dam, located in Chillicothe, Iowa, is a private-owned structure built in 1984 primarily for recreational purposes. With a dam height of 34 feet and a length of 445 feet, it provides a storage capacity of 311 acre-feet and covers a surface area of 12 acres. The dam is situated on Little Avery Creek and is under the regulatory oversight of the Iowa Department of Natural Resources.
Despite being classified as having a low hazard potential, the dam's condition assessment is currently not rated. However, the risk assessment indicates a moderate level of risk, with emergency action plans and inundation maps yet to be prepared. The dam's spillway type is uncontrolled, and it has no outlet gates. The surrounding area has a drainage area of 0.85 square miles, making it crucial for water resource and climate enthusiasts to monitor the dam's condition and regulatory compliance to ensure the safety of the community and the environment.
Overall, Maxon Reservoir Dam serves as a vital water resource for recreational activities in the area, but its maintenance and risk management measures need to be closely monitored. With its location in Monroe County, Iowa, the dam's proximity to residential areas underscores the importance of regular inspections and enforcement of safety protocols. As climate change continues to impact water resources, the resilience and sustainability of structures like Maxon Reservoir Dam will be essential for ensuring water security and environmental protection in the region.

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.

About Maxon Reservoir Dam
Where does the data for Maxon Reservoir 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.
