Patrick Lake is a 39-acre lake in Grand Marsh, Adams County, offering public boat access via a dedicated ramp facility. The lake features a maximum depth of 21 feet and supports populations of panfish, largemouth bass, and northern pike, making it popular with anglers. The boat ramp provides convenient launch access for both motorized and non-motorized watercraft, including kayaks and canoes.
The relatively modest size and depth of Patrick Lake make it well-suited for recreational paddling and casual boating. A public beach area is also available at the site. Boaters should note that motorized watercraft and non-motorized boats require permits (typically $25 and $5 respectively, available online or at the park office). The access site's location near the Ice Age National Scenic Trail corridor adds to the recreational opportunities in this scenic Adams County region.
