Hoyle And Johnson dam
Hoyle And Johnson
Hoyle and Johnson, also known as Johnson Pond, is a privately owned recreational dam located in Marinette, Wisconsin. Completed in 1974, this Earth-type dam stands at a height of 11.4 feet and has a hydraulic height of 8.5 feet, with a maximum storage capacity of 100 acre-feet. The dam serves the primary purpose of recreation, offering a surface area of 12.4 acres for water enthusiasts to enjoy.
Managed by the Wisconsin Department of Natural Resources (WIDNR), Hoyle and Johnson has been deemed to have low hazard potential with fair condition assessment as of 2011. Despite its moderate risk level, the dam has undergone regular inspections every 10 years, with the last inspection conducted in January 2014. With a controlled spillway width of 125 feet and a maximum discharge capacity of 270 cubic feet per second, the dam ensures the safety of the surrounding area while providing a unique recreational opportunity for visitors.
Located on the TR Peshtigo River, Hoyle and Johnson offers a picturesque setting with its 900-foot dam length and normal storage capacity of 53 acre-feet. With its state-regulated status and adherence to inspection and enforcement protocols, this dam stands as a testament to responsible water resource management in the region, making it a must-visit destination for water resource and climate enthusiasts looking to appreciate the intersection of human engineering and natural beauty.

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 Hoyle And Johnson
Where does the data for Hoyle And Johnson 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.
