Harrison dam
Harrison
Located in Lincoln, Wisconsin, the Harrison dam stands as a vital water resource managed by the local government. Built in 1939, this gravity dam on the North Branch Pine Creek serves primarily for recreational purposes, offering a surface area of 206 acres and a drainage area of 3.6 square miles. With a maximum storage capacity of 1200 acre-feet and a normal storage of 550 acre-feet, the dam plays a crucial role in water management in the region.
Despite being classified as a low hazard potential structure with fair condition assessment, the Harrison dam faces a very high risk due to its age and the increased demands placed on it over the years. The dam has undergone modifications in 2015, and regular inspections are conducted to ensure its integrity and safety. The dam features a controlled spillway and has a hydraulic height of 8 feet, structural height of 12 feet, and a length of 340 feet, making it a significant part of the local water infrastructure.
With Sean P. Duffy as the representing congressman for the area, the Harrison dam continues to be a key feature in the water resource management of the region. As climate change impacts water resources, the importance of maintaining and upgrading such infrastructure becomes even more critical to ensure the safety and sustainability of the surrounding communities. The Harrison dam serves as a reminder of the interconnectedness between water resources, climate change, and community well-being.
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 Harrison
Where does the data for Harrison 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.
