Mott dam
Mott
Mott is a private earth dam located in Neptune, Wisconsin, along the TR-Wheat Hollow Creek. Completed in 1971, the dam stands at a height of 29 feet and has a length of 370 feet, with a primary purpose of fire protection, stock, or small fish pond. It also serves additional purposes such as flood risk reduction and recreation, with a storage capacity of 20 acre-feet and a drainage area of 0.2 square miles.
Although Mott has a low hazard potential, its condition assessment is rated as poor, indicating a need for maintenance and repairs. The last inspection was conducted in August 2010, with an inspection frequency of 10 years. The dam's risk assessment is moderate, with a DSAC assigned date yet to be determined. It is regulated by the Wisconsin Department of Natural Resources and is subject to state permitting, inspection, and enforcement.
Given its location and purpose, Mott plays a crucial role in water resource management and climate resilience in the region. With its strategic position along the TR-Wheat Hollow Creek, the dam not only provides essential fire protection and water storage but also contributes to flood risk reduction and recreational opportunities. However, the dam's poor condition assessment highlights the importance of regular maintenance and risk management to ensure its continued functionality and safety for the community and surrounding ecosystems.
Dam data reference
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 Mott
Where does the data for Mott 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.
