Lake Poinsett is a large, shallow lake of over 5,000 acres located in Brevard County, Florida. It is part of the St. Johns River system, with the river running along county lines north of the lake. At its widest point, the lake spans 5 miles. A channel on the eastern portion connects Lake Poinsett to Lake Florence and Barnett Lake.

Paddlers can access the lake via the St. Johns River, entering from Lake Washington to the south. The route passes through Lake Winder before reaching Lake Poinsett. Be prepared for potential airboat and motorboat traffic, especially in swampy areas along the shoreline. Using a bright, tall warning flag on your canoe or kayak is recommended for visibility. Carrying a loud horn can help warn away boats if needed.

The lake offers excellent fishing opportunities, particularly for largemouth bass. Anglers can find success fishing along bulrush areas and in coves with maidencane and lily pads. The lake also produces good catches of crappie, especially in late fall and winter. Hydrilla is prevalent throughout the lake, so weedless rigging is advisable.

Wildlife enthusiasts may spot various bird species, including vultures. Alligators are present in the waters, with some of the largest seen in Lake Winder. Exercise caution, especially in shallow areas.

For overnight trips, there are campgrounds along the river, though some may be difficult to locate from the water. The Palms campground on the west shore of the river north of Lake Winder is a reliable stop.

Weather can be variable, with the potential for sudden downpours. Paddlers should be prepared for changing conditions. The lake can offer serene moments, such as mirror-like reflections of the sky after rain.

When planning a route from Lake Poinsett to Lake Florence, navigate carefully using waypoints rather than heading directly to your destination. Round the small peninsula on Lake Poinsett's east shore before heading east to the channel connecting to Lake Florence.
