Mullet Creek dam
Mullet Creek
Mullet Creek in Fond du Lac, Wisconsin, is a state-regulated Earth dam completed in 1971 with a primary purpose of serving as a Fish and Wildlife Pond. This dam has a height of 9 feet and a length of 1800 feet, providing storage of up to 1250 acre-feet of water with a normal storage capacity of 500 acre-feet. The dam has a low hazard potential, but its condition assessment rated as unsatisfactory as of May 2015, indicating a need for maintenance or upgrades.
Located in the Chicago District, Mullet Creek's spillway type is controlled, with a maximum discharge capacity of 180 cubic feet per second. While the dam's risk assessment is very high, it is important to note that it has not been USACE (U.S. Army Corps of Engineers) designated. The last inspection was conducted in April 2005, with a recurring inspection frequency of 10 years. The dam's risk management measures, emergency action plan (EAP), and inundation maps status are currently undetermined, highlighting a need for further evaluation and preparedness in case of emergencies.
For water resource and climate enthusiasts, Mullet Creek presents an intriguing case study in dam infrastructure and management. With its state-regulated status and critical role in supporting fish and wildlife, the dam's condition assessment and risk factors underscore the importance of ongoing monitoring and maintenance. As climate change continues to impact water resources, ensuring the safety and effectiveness of structures like Mullet Creek is essential for both environmental conservation and public safety.

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 Mullet Creek
Where does the data for Mullet Creek 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.
