The Wisconsin River Flowage, located in north-central Wisconsin, offers paddlers a scenic and secluded experience. With approximately 6,800 acres of water and 72 miles of shoreline, this reservoir provides ample space for exploration. The flowage was created in 1937 for flood control and river flow management.

Access points include Veterans Memorial Park in Prairie Du Sac, which has ample parking and camping facilities. The Arena boat landing, about 14 miles downstream, features both a traditional boat ramp and a designated canoe launch on a sandy beach.

While not highly populated, the flowage does see some motorized boat traffic, particularly in the upper sections closer to Prairie Du Sac. Paddlers should be aware of potential wakes and waves. Water levels can change rapidly due to dam operations and rainfall, affecting currents and sandbar availability.

Notable sights include Ferry Bluff State Natural Area, where towering bluffs line the river. The George Mead Wildlife Area borders the southeast end, providing scenic forest and marshland views. Wildlife spotting opportunities abound, with bald eagles, ospreys, pelicans, and various waterfowl frequently seen.

Sandbars are plentiful at lower water levels, offering excellent camping options. No permits are required for camping on sandbars or islands within the Lower Wisconsin State Riverway. However, camping is prohibited within one mile upstream or downstream of the former Mazomanie Beach area.

Water quality has faced challenges, with fish kills occurring in 2009 and 2013 due to low oxygen levels from agricultural runoff and other factors. Recovery efforts are ongoing. Despite these issues, the flowage remains known for northern pike, walleye, crappie, and smallmouth bass fishing.

For day trips, a 8-12 mile paddle is generally recommended, accounting for water levels and wind conditions. The stretch from Prairie Du Sac to Arena (14.25 miles) makes for a popular full-day journey.
