Donnell Lake connects to Lewis Lake via a navigable channel, effectively creating a two-lake system accessible from a single launch. This connection is a real asset for anglers looking to cover more water without trailering.
Donnell Lake freezes in winter and likely supports ice fishing given its location in Cass County. Walleye and pike through the ice would be the primary draw. Always verify current ice thickness locally before heading out — conditions can vary across the lake, especially near the channel to Lewis Lake.

Where is Donnell Lake?
Donnell Lake is a 401-acre lake in Cass County — small enough to feel intimate but big enough for real boating and decent fishing. The water is notably clear by southwest Michigan standards, and locals consistently call it one of the cleanest lakes in the area. A channel connects Donnell Lake to Lewis Lake, opening up extra fishing territory without having to trailer to a second launch. The east end of the lake has an island that draws swimmers on summer weekends, which can make that section busy — anglers do better hitting the water early.
Walleye, northern pike, and bluegill are the main targets here. The lake has some real depth to it, which helps keep water quality high and supports a mix of species. The single public launch gets a 4.9 rating and is reportedly uncrowded on weekday mornings, though summer weekends bring heavy recreational traffic. Several campgrounds sit within easy reach — Shady Point, Camelot, and Lakeside among them — making this a solid base for a southwest Michigan lake weekend. The surrounding community is tight-knit and welcoming, with a genuine locals-love-it-here vibe.
