After conducting research, I was unable to find any information regarding a boat ramp specifically named "Comus Lake" in Wisconsin. However, there is a boat ramp located at the coordinates provided (latitude: 42.63759995, longitude: -88.6497345) which provides access to Lake Comus.

According to the Wisconsin Department of Natural Resources, the boat ramp at Lake Comus is a concrete slab ramp that is 30 feet wide and has a maximum parking capacity of 10 vehicles. The ramp is suitable for launching small and medium-sized boats, including fishing boats, canoes, kayaks, and pontoon boats.

Lake Comus itself is a small, 66-acre lake located in Walworth County, Wisconsin. The lake is known for its clear waters and popular with anglers, especially for catching panfish, largemouth bass, and northern pike. The lake is surrounded by a mix of residential and undeveloped land.

In terms of regulations, all boats launched on Lake Comus must comply with Wisconsin boating laws, including having the required safety equipment on board and obeying all boating speed limits and rules. Additionally, there are no specific restrictions on the use of motorized boats on the lake, but there is a no-wake zone in place near the boat ramp area to ensure safe and orderly boating activity.
