Safety and flow rates around
the Great Pinery Heritage Waterway
When paddling on the Wisconsin River, safety should always be your top priority. Be sure to check current flow rates and weather conditions before heading out, as both can greatly affect water levels and speed. Always wear a life jacket, be mindful of changing conditions, and have a plan in place for emergencies. Additionally, avoid paddling alone, stay aware of any obstructions in the water, and respect local guidelines to ensure a safe and enjoyable adventure on the Great Pinery Heritage Waterway.
Portage safety
The Great Pinery Heritage Waterway has nine historical dam portages that range from a couple hundred feet to over a mile in length. Safe portaging begins upstream from a dam well before you see or hear it!
- Study a map beforehand to locate potential dams and hazard locations or ask a local for more information about dam locations. Each dam portage has been included on the website giving directions on what side of the river to approach from the upstream paddle. Each portage can be downloaded.
- Always be alert for potentially dangerous situations.
- Always portage around the structure or turn around well before reaching the dam when kayaking or canoeing.
- Obey all posted signage and barriers in the area.
- Let someone know when and where you are heading out and when to expect your return.
- Keep your distance, keep your life: Always stay a safe distance away from dams both upstream and downstream to avoid drowning.
- Never enter the water to try and help someone. Instead, call 911 and use a remote assistive device, such as a rope or throw bag, to try and pull them back to safety.

River conditions and water levels
The Wisconsin River is subject to fluctuating water levels influenced by rainfall, dam releases, and other natural factors. Understanding water levels, typically measured in cubic feet per second (cf/s), is crucial for planning trips and ensuring safety. Here’s a breakdown of water levels and corresponding river conditions:
- <3,000 cfs: Shallow river, ample sandbars; suitable for maneuvering downstream.
- 3,000-10,000 cfs: Typical summer conditions, numerous sandbars, easy navigation.
- 10,000-15,000 cf/s: Limited sandbars available; camping spots may be scarce.
- 15,000-17,000 cf/s: Few sandbars, limited camping options; caution advised, especially for inexperienced paddlers.
- 17,000-20,000 cfs: Scarcity of campsites, most sandbars underwater; overnight trips not recommended.
- >20,000 cfs: Challenging conditions, no sandbars available for camping.
Background information
Understanding the relationship between flow rates and river depth is crucial for assessing safety and suitability for paddling. High flow rates indicate pushier and potentially more dangerous river conditions, while low flow rates offer gentler currents and ample sandbars for camping. Flow rates above 17,000 cfs on the Wisconsin River may render camping trips unsafe, while flow rates below 10,000 cfs provide ideal conditions for paddling.
Water alerts
Utilizing resources like the USGS WaterAlert feature allows paddlers to receive real-time updates on water levels, enabling better trip planning and monitoring of river conditions. By setting up alerts based on specific parameters, paddlers can stay informed about changes in water levels and make informed decisions about their trips.
Understanding flow rates is essential for safe and enjoyable paddling experiences. By staying informed about water levels, interpreting flow rate guidelines, and utilizing resources like water alerts, paddlers can plan their trips effectively and mitigate risks associated with fluctuating river conditions. Whether navigating gentle currents or facing challenging rapids, awareness of flow rates is key to enjoying the beauty of rivers responsibly.
