Located in Cortland off State Route 305, the Causeway Sport Shop provides boat ramp access to Middle Mosquito Creek and connects to the broader Mosquito Lake system. This is a marina concession ramp at the main entrance, making it a convenient launch point for paddlers and boaters heading out on the water. The nearby Mosquito Creek Lake offers excellent fishing opportunities for walleye, crappie, bass, perch, bluegill, and catfish.
**Important considerations:** User reports indicate the ramp is in poor condition and quite narrow—boaters should be prepared for a tight turnaround area and may need to remove their boat from the water to maneuver safely. The proximity of the break wall limits maneuvering space, so this launch works best for smaller vessels and paddlers comfortable in tight quarters. A state park boat launch is also available across from the marina for state park campground users.
Before visiting, check current conditions with the facility, as water level fluctuations and facility maintenance can affect usability. This access point is best suited for experienced paddlers and boaters familiar with launching in constrained spaces.
